How does a doctor-on-demand app work?

Doctor-on-demand apps connect patients to healthcare industry specialists and provide professional consultations on the go. Generally, there are three roles in the app: a doctor, a patient, and an administrator. Each role requires different functions that do not intersect. The share of doctors and patients is almost equal. So, paying careful attention to doctor-on-demand app development on both of these levels is important.

Many factors have contributed to the growth of doctor-on-demand services:

    • Increase in offline healthcare costs
    • COVID-19 pandemic
    • Digitalization of all areas of life, including healthcare
    • High quality of online health service (narrow specialists, doctors that are not available in certain areas, top-ranking professionals)
    • Convenience of the telemedicine services (no lines, no travel time, no papers — all data is online)

For these reasons, a medical consultation app is a must on a modern person’s smartphone.

Top 3 doctor-on-demand apps

If you’re going to make a doctor-on-demand app, check out the leaders of the market and the main features that popular applications incorporate.

Doctor On Demand

One of the market pioneers, this consultation app provides 24/7 virtual healthcare. Hundreds of medical professionals available here are licensed and certified. The main features of this telemedicine app include video calls, an elaborate search function, and integrated maps that allow users to find nearby pharmacies and contact them.

The Doctor On Demand app not only has a wide range of therapists and physicians but also upscale psychiatrists and psychologists who provide mental health treatment.

This telemedicine app offers multiple healthcare services. It’s a family savior in the full sense of the word — even pets can get an online treatment, as the list of app doctors includes veterinarians. The distinguishing feature of the Medici app is an opportunity for a patient to invite his own doctor or healthcare provider to join the service. There is also a group chat where a council of several specialists can be arranged.

This doctor-on-demand app allows patients to get connected to their own pool of family doctors. And healthcare workers, on the other hand, can manage their clients and get quick access to their history.


The Telehealth app is famous in the healthcare industry for connecting doctors and patients either by video or by audio and text. Users who live in remote areas or have a slow internet connection can choose the options that require less mobile data to access the service.

Another eye-catching feature of this doctor-on-demand app is starting video appointments instantly: no login or password required.

Nice-to-have features

The doctor-on-demand apps market is rather competitive. To stand out and achieve a better user experience, having core features may not be enough. Here are a few ideas on additional features to make a healthcare app indispensable to users.

    • Notifications not to miss the time of appointments and important messages
    • Reviews and ranking system to find the most relevant specialist
    • Loyalty programs to get some perks and benefits from being a long-term user
    • Newsletter with health-related articles and tips to be up-to-date with industry news
    • Video recording to rewatch the consultation with a doctor and recall what was forgotten

How to make money with a doctor-on-demand app

There are several ways to make doctor-on-demand mobile apps profitable.

    • Commissions. Either from patients or from doctors or clinics. Commissions are the easiest and most natural way to get direct revenue for using the app.
    • Paid listing. Highlighting certain doctors with badges, special designs, and top lines in search charts. Paid promotion of clinics.
    • In-app ads. An easy way to make money on the app is by adding other brands’ advertisements into your app. Keep the number of ads reasonable and make sure that users are not irritated. Better show ads based on the user’s history.
    • Subscription. Users can get discounts when using monthly or yearly subscriptions instead of paying for a service each time.

Doctor-on-demand app development best practices

We’ve already discussed that on-demand doctor appointment app development may require building core features, without which the app will not be competitive in the telemedicine market. What helps the app stand out are the little things.

Check out these doctor-on-demand app development best practices that can make a difference.

    • Design. User experience needs to be flawless — the main features of the app need to be only a couple of clicks away. Bear in mind spreading this practice on all devices, as we did in online psychotherapy app. A desktop version displays the whole function block without distorting the proportions or making users scroll down.
    • Modern video communication capabilities. Allowing users to use group video calls or a chat in a separate window can become a valuable feature for effective consultations.
    • Security. The healthcare industry is all about trust. Doctor-on-demand apps should not only have a clear and stable payment system but security at all levels. Purrweb’s Clearstep app provides doctors with patients’ personal data that can be used only within the app.

Tech stack for doctor-on-demand app development

The technology required for a doctor-on-demand app development depends mainly on the platform we’re using. Be it a mobile (Android or iOS app development), web, desktop application, or all at once — the telemedicine app development tech stack will differ.

    • Electron.js for desktop doctor-on-demand apps. It allows developers to create cross-platform desktop applications using JavaScript, HTML, and CSS.
    • React.js and Node.js for web doctor-on-demand apps. React.js and Node.js are open-source JavaScript libraries that can help to develop a web doctor appointment app.
    • React Native for mobile doctor-on-demand apps. React Native is a framework used for Android and iOS app development. It helps to develop applications for two platforms using a single code base.

We at Purrweb find React Native to be the best framework for cross-platform app development. You will need only one cross-platform team instead of two native teams to release your mobile app on iOS and Android platforms.

How to create a doctor-on-demand app

The app development process, no matter what type of app it is, generally looks like this: Project analysis ➡️ UI/UX design ➡️ App development ➡️ QA ➡️ Release and post-release support. We thoroughly discussed all stages of developing all kinds of apps here.

We at Purrweb always advise startups to build an MVP — Minimum Viable Product. It is the first version of your app. MVP can help you gather valuable user feedback and check feasibility while at the same time being a perfectly working application.

Now, let’s explore the mHealth app niche precisely. How to build a doctor-on-demand app, and what steps are specific here?

Step 1. Obtain medical certifications

When you develop an app in a medical niche, it’s not enough to research the market and analyze your competitors. Every country demands different certifications you should get before launching an app.

For a doctor-on-demand application to function in the US, it must meet the standards of HIPAA, FDA, HHS, and others depending on the provided services. European doctor-on-demand apps require EPSC certification. We have a great article on HIPAA compliant app development, so you can learn everything you need to know.

Step 2. Choose principal functions

What is the main thing a doctor-on-demand mobile app user wants? Analyze your target audience and select 2 or 3 main functions that distinguish the service from others. That may be group video calls, synchronization with smartphone health trackers, speedy scheduling, chatbots, etc.

Step 3. Provide data security

As we’ve previously discussed, trust and security are pillars of the healthcare industry. Ensure that doctors get thoroughly verified and patients’ data is protected. For example, only doctors and patients themselves should have access to EMR (electronic medical record). To respect the patients’ privacy, the administration should not be able to view any EMR or other personal health information.

And last but not least — provide a secure payment gateway for in-app transactions.

Step 4. Develop impeccable UI/UX

​​The app will have separate parts for doctors, patients, and administrators. All three parts will have different functionality, user interfaces, and technical feasibilities. You don’t want to mix them up.

Step 5. Build a doctor-on-demand app and test it

Choose your desired platforms and hire a team of developers or a mobile app development company. The cost of a doctor-on-demand app is mainly determined at this stage.

Step 6. Release

You’ve gone through all the stages of the doctor-on-demand app development process and are ready to release a working telemedicine app.

How much does it cost to develop a doctor-on-demand app?

Here’s Purrweb’s doctor-on-demand app development cost and timing breakdown. Bear in mind that these are approximate numbers. We based them on our calculation of an app with basic functionality: no admin panel or video.

Stage Estimation in hours Approximate costs
Project analysis 40 $800
UI/UX design 180 $8,100
App development 1500 $54,000
QA (Quality Assurance) concurrently with the development $10,000
Project management during the whole project $11,000

Overall, you will need approximately $83,900 to create your own basic functionality app. And the application development process will take 1,720 hours, which equals 2-3 months.

Depending on the staff involved and the desired functionality, the doctor-on-demand app development cost can be lower or higher.

Case studies

We at Purrweb are familiar with building successful mHealth apps. Here are some insights from our doctor appointment apps portfolio. You can read more about the design and development process of these projects in our other articles.

Online psychotherapy service

Patients can be sure that in the My Therapy Assistant app, they get the best mental health treatment, as the doctors are carefully selected. Having downloaded the app, a specialist undergoes a detailed registration process and an interview to prove his qualifications.

In order to work effectively, he needs to meet certain requirements, such as answering patients within 6 hours, updating the calendar, and opening at least five slots per week. This is controlled by a powerful scheduling feature.

On the user’s side, it’s all smooth and easy, with plenty of features to satisfy any need — a chatbot, calendar, notes, video calls, and a window management feature. You can minimize a call window and continue using the app.

Clearstep doctor-on-demand app (known as Lytic Health at the time we designed it) helps automatically determine preliminary diagnoses and schedule appointments. The crucial feature here is a chatbot that collects primary information about the patient’s symptoms and thus, frees up the doctor’s time.

Another unique feature is a clear dashboard. Thanks to it, a doctor can see relevant information about all his patients, sort them according to the urgency of the case, and quickly access one-on-one chats.

Purrweb’s design helped the startup to get a $400,000 investment and proceed with an upscale doctor-on-demand app development. How did we do it? Read about it in our article.
