The economy of human resources. Create a doctor appointment app - mean give patients the opportunity to take care of records management, and take all the necessary data, and medical reports automatically through an app. It significantly saves working hours.

No queues. It’s vital in pandemic circumstances that the automation of medical services eliminates the need for patients to queue at the reception, creating unfavorable covid conditions.

Elimination of human error. Since the appointment scheduling is automated, there is no chance that the operator will make a mistake, which will cause a waste of time and money for doctors, the patient, and the hospital in general.

Top 4 Doctor Appointment Booking Apps


This world-renowned application began its journey as a startup for Manhattan dentists in New York in 2007.

In 2008, the project began to receive millions of investments, which helped it grow into a large project, which had covered 40% of the market in 2,000 cities across America in 2014.

In 2020, under the pandemic influence, product owners launched a telemedicine function.

The monetization model of this app includes a subscription fee (for doctors and clinics), a fee for each booking, and paid listing (the ability for doctors to use marketing tools to promote rankings). Patients can use this platform for free.

Today Zocdoc has 6+ Mln monthly active users, and offers them:

  • 1800 types of medical services;
  • online reception management with a notification system;
  • 50+ categories of specialists;
  • reviews and ratings of doctors based on patient assessments;
  • telemedicine for real-time communication with a doctor online or an appointment for an offline visit.


The history of MFine began with the fact that the top managers of the large-scale e-commerce project Myntra decided to develop a doctor appointment app for the Indian market.

The project was founded in 2017 as an m-health platform. Nowadays, it covers 1,000 Indian cities.

Unlike Zocdoc, MFine cooperates not with individual doctors but with medical institutions.

The main emphasis is on artificial intelligence and the Internet of Things for chronic disease treatment with the ability to connect medical equipment. These all make the app a perfect tool for clinics to digitize their services.

MFine currently works with 700 clinics and can offer patients 6,000 doctors in 35 medical specialities. Users can manage appointments via chat or voice booking and get medical consultations in person or through telemedicine.

MFine earns revenue by charging a fee for booked visits and lead generation


It is a healthcare platform providing services to users from India and Singapore.

Its history began in 2008 with the creation of the Turbodoc application. It got its current name two years later. The platform is positioned as an independent unbiased app for patients, which allows you to find a doctor, manage appointments, search for laboratories, order meds, and store health data. This app can work as a tool for hospitals for digitizing services and automating processes.

Practo provides profitability through a licensing fee - as a Software-as-a-Service available by subscription.

The service covers more than three hundred cities across India, and more than 30,000 bookings are made through it every month.

Both doctors and patients can use the application for free. However, there are also two advanced service packages at an additional cost: the CM Atom plan for Rs 999 and the Clinic Management plan for Rs 1999.

Doctor On Demand

This service for finding doctors dates back to San Francisco in 2012.

Today, 98 million Americans use this application.

Its users have access to 24/7 access to medical care online, e-prescriptions, telemedicine, storage of material records, and the possibility to use insurance.

The service receives income from patients who pay for themselves or with the help of an insurance company. Also, a fee is charged for each booked reception. The usual price for a 15-minute standard physician’s appointment will cost the patient $75 - if it is a treatment for somatic problems. The price of a psychotherapist’s consultation is $129 for a 25 min consultation and $179 for a 50 min consultation. Psychiatrist services will be the most expensive: $299 for 45 min consultation and $129 for 15 min follow-up.

Key Features of Doctor Appointment Mobile App

Users’ profiles

For the doctor

The doctor’s account must include a photo and basic information about education, accreditation, specialization, licenses, and experience. There should also be an appointment button, and it will be great, especially if the patient can calculate the approximate cost of the appointment/treatment in advance.

For the patient

The patient should have access to his medical records, research results, treatment plan and anamnesis. Equip his profile with the ability to fill in the personal data, contact and medical information, treatment and appointment planning features.

Searching engine with advanced features

If you create a doctor search app with a large client base, include an item on the advanced search process implementation in the on-demand doctor app development plan. Provide the user with a custom search function by category, location, medical facilities, names of specialists, types of medical services, or health problems. You can add filters by price, popularity, number/percentage of positive reviews, and date.

It will help the specialist and the patient search for each other more respectively, which will affect both the loyalty of your users and profits.

Appointment management

Appointment Management

Calendar, reminders, push notifications - use these features to automate appointment management. So your client will not only be able to make an appointment or cancel/reschedule an appointment at any convenient time but will also be aware of planned studies, examinations, and free time slots. It’s also useful for doctors and clinics to minimize the waste of time due to canceled or rescheduled sessions.


Equip the application with chats so that doctors can communicate with patients, share third-party materials, ask and resolve questions, clarify information misunderstood or misunderstood during the appointment, and resolve organizational issues without the need to schedule a separate session.



It will make life easier for both medical staff, who will not have to spend time writing prescriptions, and patients. They won’t have to visit a doctor/clinic to get a prescription and can have it with them - on their smartphone - when they need to buy medicine. World practice shows that the transition to e-prescriptions is already underway. For example, in the United States, in 2020, more than 80% of prescriptions were already electronic.

Payment module

You need to provide users with comfortable payment methods: linking bank cards, e-wallets, online banking, and various currencies. But in addition to comfort, think about safety. One of the most common secure options is a payment gateway. In addition to paying for services as a customer, you can use this tool to receive payment for advertising/promotion. For example, to implement a paid listing monetization model.



69% of patients using online patient appointment do so via video conferencing tools instead of regular phone calls.

So the telemedicine function is a definite must-have in a doctor appointment booking system development. It can be implemented by developing your custom tools or integrating existing solutions, such as ZOOM and Google Meets.

How Does an On-demand Doctor App Make Money?

How On-Demand Doctor App Makes Money

Commission-Based Model

This model is quite simple: the medical supplement is paid in the form of a commission for each paid medical appointment. Applications can also charge for generating new clients (such as MFine).

Paid Listing

This model works through marketing tools that allow you to promote certain doctors to the top of the list when searching by category.

Subscription fee

Here, the client pays for the subscription to the medical consultation app regularly. If you are planning to build an app for booking doctor appointments on this business model, keep in mind that there are patient-oriented and doctor-oriented resources. The former is free for the end-user, and doctors pay. In the second case, the opposite is true. You can also use this model in a slightly different way - to offer an advanced version with additional app features for a paid subscription for both doctors and clients.


With this model, you can earn money from advertisers and also offer the use of your health care application without advertising for an additional fee.

8 Steps of Doctor Appointment App Development

8 Steps of Doctor Appointment App Development

Detailed analysis

You need to know everything about customers, market, and rivals. Surveys of potential users should include as many categories as possible to be representative.

As for the market and competitors, you’ll need statistics, and it will be great to look at the market leaders - test their products, and read the reviews. Find their strengths and weaknesses to understand development areas for your application.

For self-analysis, you can use such services as Statista and Google Analytics.

But it’s better to turn to professional discovery teams. Some software developer firms provide related consulting services. It’s a great option because such specialists have encountered on-demand doctor appointment app development in a personal experience, so they can provide unique information, even tailored to your specific business idea.

Choosing technical partner

When searching for a healthcare software development services, you should pay attention to the following criteria:

  1. Experience. To ensure the company’s expertise, check the portfolio, make an organizational call, see examples of ready-made projects, and read other customers’ reviews (it’s better to prefer independent sources such as CLUTCH).
  2. Terms of cooperation. A reliable company will offer you transparent cooperation terms and in several variations. Clarity, simplicity, and detailed discussion of all organizational aspects - are the main features of an experienced, professional, responsible, and honest team.
  3. Outsourcing. Take a look at this option. Here, the outsourcing development company takes full responsibility for the team setting, the organization of communication and work process, as well as delays. You don’t have to worry about things like equipment or office rent. On the other hand, development costs are relatively low if you choose a company from Eastern Europe, for example, where the level of education and professionalism is quite high, and ratings are relatively low due to the lack of large-scale projects in the local market. In addition, a well-coordinated team will work on your project on clear terms and with deadlines, which would not be so easy to organize when hiring freelancers.

Planning: budget, technology, methodology, team

At this stage there is detailed planning:

  • Budgeting, team setting, and choosing a tech stack. These things are directly related. A well-thought-out stack for the project will help optimize the cost of doctor on-demand app development and working resources. So, by choosing React/React Native Stack, you’ll spend 30% less money on hybrid development than in the case of native development. In addition, you can build an app simultaneously on both platforms (iOS and Android). And thanks to flexibility and simplicity, these technologies allow virtually unlimited scaling and modification of the application. Not surprisingly, 40% of projects are built using React, and it’s the highest figure among frameworks.
  • Features. It’s necessary to determine the feature set and divide all functions into key and additional ones. The first will implement primarily at the MVP stage, and the rest - later during the iterations of the Build-Measure-Learn cycle.
  • Methodology. In practice, we have identified the best methodology - Agile, which we use with the Scrum approach. This combination gives an excellent performance and provides simplicity and high development speed. Statistics confirm that this is indeed one of the best methodologies. Thus, 71% of projects in the US are made with the help of Agile. In 94% of cases, this technology is combined with Scrum.

Design creation and prototyping

At this stage, UI/UX specialists create a prototype of the future application. Why do you need it?

  1. Concretization of goals and objectives. With the finished design, the team will have something to start from, and it will be easier to divide the workload into parts.
  2. Ability to anticipate difficulties and avoid them when building software.

Increasing investment prospects - having a rough idea of the project, investors are more willing to invest in it.

Development and testing process

Scrum Agile methodology involves the organization of the development process for sprints. Each new sprint begins only after planning, implementation, analysis, and approval of the previous one by the product owner. In this way, the application owner retains control over the process and avoids confusion, because the application is building consistently. It also provides timeline benefits. The detailed division of work into stages - milestones with clearly defined deadlines for each one is more accurate to calculate the implementation timeline and establish clear areas of responsibility for delays between team members.

A significant part of development is testing. Carrying out testing on each milestone will give you quality assurance and solve possible problems in advance.


At the deployment stage, it’s vital to ensure uninterrupted communication and timely updates of changes with product-owner notification to achieve rapid product launch. CI / CD technology will be the perfect tool for this.

Post Launch support

Doctor appointment mobile app development doesn’t end after the product launch. Сonversely, once the MVP is ready and you receive the first revenue and feedback, it gives you an incentive for further improvement. During the Build-Measure-Learn cycle, you collect, analyze user feedback, plan for application improvements, implement changes, and start a new iteration. As a result, by minimizing financial risks, you’ll gradually improve your product while maintaining complete control over the process.

Doctor Booking App Development Cost

Doctor Booking App Development Cost

On average, an application for online medical booking costs from $15,000 to $40,000. But these are average figures for small or medium-sized projects. The final project cost can reach a million dollars - there is no final maximum mark. It all depends on various factors, which we’ll discuss below.

Complexity level

Doctor booking app development cost directly depends on the complexity and scale of the project. Yes, a small app for booking receptions can be developed in 2-3 months, spending $15,000- $30,000.

If you are interested in a more complex idea, it will take much more time and time - at least six months and $50,000.

For this price, you can get, for example, a chat app with the function of voice booking of receptions using a bot, or an application with electronic prescriptions, storage of patients’ personal data, and medical history analysis.

And the most expensive will be the apps such as Zocdoc, which uses machine learning and artificial intelligence. Its development takes more than one year and continues relentlessly, respectively, and its price continues to rise.

Development team

Hiring a team yourself, maintaining an office, and purchasing equipment will significantly increase the cost to develop your application.

It’s much more profitable to work with freelancers. This option, unfortunately, doesn’t eliminate the need to participate in the organization of work and doesn’t provide reliable guarantees of quality software development, clarity of deadlines, and coherence of communication. But you can turn to outsourcing companies. When choosing them, pay attention to localization. The rates of developers from Western Europe and the United States are the highest in the world, ranging from $65 to $130. While engineers from Eastern Europe aren’t inferior to them in terms of service quality. The relatively low rates of local specialists (namely $30–$65) are due to the lack of large-scale local projects, as well as lower prices for office maintenance than in the United States.

Codempire is the company that can provide you with a perfect price-quality ratio and transparent cooperation terms.

Smart bugging, selecting the perfect technology stack, hybrid development on two platforms, 100% data security, perfectly established communication, responsibility, and timeliness - all these, our company provides to customers, making their business stories successful.

Marketing cost

At the time of 2020, more than 350,000 healthcare applications were available to users, and 83% of them were downloaded less than 5,000 times, while the vast of downloads fell on the most famous and popular applications.

Therefore, to ensure the visibility of your application, order a promotion on social networks, other applications, and web resources. Set aside about $10,000 for this purpose.

Ghaya Care

Our customer was a Dubai company specializing in-home care for patients.

The idea was to create an application to find services from professional nurses, including regularly.

The main challenge was to provide a high level of service. It was necessary to equip the application with the ability to collect feedback and respond to it.

The application was created by two engineers using React Native stack.

For the server part, we used Firebase.

Implementation was completed in 3 months, without delays and problems - thanks to the well-established communication and Scrum Agile methodology.

Thanks to the hybrid development method, the client saved about 30% of finances compared to native development.

Now Ghaya Care has more than 500 satisfied customers who have the opportunity to evaluate the service on a five-point scale, leave feedback, adjust the schedule of staff visits, and change the employee as needed.


Our Bolivian technical partner wanted to build a doctor appointment app. The main task was to provide users with the opportunity to receive consultations and treatment remotely. This on-call app was to become one of the few solutions in the Bolivian market and solve the problem of the availability of medical services under quarantine restrictions.

  • We have assembled a team of 4 engineers who created the app to book a doctor’s appointment using technologies React.js, TypeScript, Node.js, and Nest.js.
  • We chose MongoDB as a database and AWS - for cloud storage.
  • The application has a telemedicine feature (through integration with Zoom), an advanced search engine (with location, clinics, doctors, and specialties filters), online booking, and management appointments.
  • Tumedico app has launched successfully, and now it has more than 500 registered doctors.

More than 5,000 hours of online consultations have been carried out through the app.

Product-owner increased the number of customers by 30% thanks to our software.


M-health projects are a rapidly developing and profitable field. About 80% of healthcare businesses currently use medical staff scheduling software, and the market estimates at 38 billion.

The doctor appointment booking app development brings benefits to both healthcare business owners and software vendors. For the business owners, it increases customer loyalty, increases their number, and optimizes costs (by reducing the number of canceled receptions and saving working resources through automation). For vendors, it provides access to a large market with high demand for such products. In addition, healthcare mobile development brings 25% of profitability and licensing of the finished product - up to 35%.

Project monetization can be carried through commission-based, subscription fee models, paid listing, and advertising. These models can be slightly modified and combined.

The total cost of developing a doctor appointment app varies from $15,000 to $40,000, depending on the complexity, project scale, engineers’ rates, and marketing cost (which average price is $10,000).

The Codempire team has built its expertise on the experience of successful healthcare projects so that we can follow your idea from the introductory consultation stage to the post-launch improvement.

Is an MVP stage obligatory?

Minimum Viable Product is a simplified, ready-to-use version of the software. It is the best development solution that helps to optimize costs and reduce implementation time without losing quality. How does it work? When a simplified version of the application is completed and launched on the market, the Build-Measure-Learn Cycle starts. It involves collecting customer feedback, analyzing it, and gradually improving a project within each cycle iteration. If you start to develop a doctor appointment booking app for iOS/Android from the MVP stage, this gives you the following benefits: 1. Quick launch, first income, and customers; 2. Avoiding the risks related to the wrong choice of app functionality; 3. Financial risk reduction - the commercial failure of a small, simple application will not hit your financial capabilities as hard as a full-fledged one; 4. A ready-made MVP is more attractive and promising for investment than a hypothetical business idea or prototype.

Which stack to choose for the healthcare product?

Based on our experience with projects of various directions, scales, and features, we have formed a stack that demonstrates the greatest flexibility, convenience, and efficiency. For the frontend part, this is React React Native technology. What it gives: 1. Flexibility and perfect scaling. You can start a tiny startup and gradually develop it into a global mobile platform without worrying about the app quality. 2. Comprehensive community support, providing many ready-made technical solutions with free access. 3. Relatively easy to learn technology. It requires a superfluity of specialists, which means a higher probability of hiring a qualified development team. 4. Possibility of hybrid development. You have a single code base for the application on both platforms (iOS, Android) and the web version of the product. The best backend choice will be Node.js, bundled with the NestJS framework because it provides: 1. No overloading issues; 2. Flexibility in modifications; 3. Perfect speed. Among databases, the best are: 1. PostgreSQL - as it provides great opportunities to protect the personal information of users; 2. MongoDB, which is ideal if speed and flexibility are a priority. Among cloud bases, our favorite is AWS, because it is the largest cloud base that can offer you more than 1000 services and preferential terms for startups.

How to secure personal information?

To be competitive in today's mHealth market, you need to ensure the security of PHI (protected health information) for both doctors and patients. To this end, there is a worldwide practice based on HIPAA compliance. It's an American law providing for the protection of personal medical data. Therefore, there are basic tools for ensuring the security of information: 1. Encryption - using SSL / TLS protocol and secure cloud systems such as AWS; 2. A multifactor authentication is a must-have tool for many applications, not just mHealth. It can be an authorization with a confirmation code, a fingerprint, etc. (2 factors will suffice). 3. Automated Data backup using cloud services; 4. Medical license verification - to certify the doctors' qualifications. Using these tools, you'll be able to create a doctor scheduling app that users can trust, and then you'll avoid problems with legal issues and customer loyalty.
