How do telemedicine apps work?
Before we learn how how to build a telemedicine system, we need to understand how it works. To put it simply, telemedicine provides medical services remotely between patients and healthcare providers. To start using telemedicine, they need custom software, specific hardware such as a camera and microphone.
Below you can see a typical telemedicine visit workflow.
What are the major telemedicine app types?
Before developing a telemedicine app, you should define what app type you need. Currently, we can divide telemedicine software into several types. Let's go through them.
- Remote patient monitoring (RPM). This type of telemedicine app is used to treat chronic diseases. RPM apps receive data from special medical devices that patients use at home, such as glucose meters, heart rate monitors, etc. Medical specialists, in their turn, monitor the patient's condition and quickly respond to any changes.
- Electronic prescription software. To make the prescribing process seamless and control the misuse of prescription medications, practices and pharmacies use this type of telemedicine app. Patients can apply for a required recipe online and wait for its submission. When prescribing medications, healthcare providers rely on patients' EHRs that electronic prescription app stores.
- Online video conferencing. This telemedicine app allows patients and doctors to communicate in real-time via camera. Video conferencing apps make a doctor consultation like in real life, allowing people to get qualitative medical advice wherever they are.
- Mental health app. To treat PTSD, ADHD, and depression, people are increasingly turning to telepsychiatry. Using video and audio chatting allows doctors to provide mental health services to patients in a convenient and comfortable way.
- Store-and-forward. This type of app collects and transmits recorded patients’ medical history to healthcare specialists who use it to provide an accurate diagnosis and quality treatment. Store-and-forward apps keep patient medical records in the form of text, multimedia like photos or videos, and records of interaction between doctor and patient.
After covering the main types of telemedicine apps, let’s learn more about the essential telemedicine system features you should consider to build a telemedicine app successfully.

What are the key features of a telemedicine app?
Telemedicine application developers should pay attention to several aspects before embodying their innovative ideas.
Aimed at connecting patients and medical specialists on demand, a telemedicine app should consist of three interconnected elements — the patient’s interface, the doctor’s application, and an admin panel. You may create one mobile app with three corresponding profiles or two separate applications with a single backend. Your decision will define the architecture of your system.
Patients choose telemedicine apps for multiple reasons. Whatever functionalities and features you select for your application or minimum viable product (MVP), you should strive to meet all end-users' expectations.
Patient’s telemedicine app features
A patient’s algorithm of using the app for communication with a doctor is the following: once they have signed in with an app, they browse doctors’ profiles to choose the needed specialist. The app allows them to see the doctor’s availability and schedule an appointment.
A real-time telehealth visit may be held via video call to enable the doctor to examine them. The patient describes their symptoms and receives a prescription, if needed.
This fundamental algorithm may consist of the following app features, although an MVP can make do without some of them:
- Registration. This process should be quick and straightforward, enabling users to create a profile without difficulty. If the process is too complicated, the user may give up and choose another app. Users like simple registration options via email or phone numbers, but modern threats to sensitive patient data require more robust authentication methods.
- Patient profile. Patients’ profiles should contain personal data such as name, age, gender, address, contact details, medical history, notes from previous visits, and other data that may be necessary for efficient diagnosis and treatment.
- Search and filters. Filters facilitate the search process and enable the app user to find the best doctor, considering their needs and situation. This feature is convenient for patients who care for their specialist's specialty, language, gender, the doctor’s rates, and insurance provider.
- Appointments and calendar. Patients must book an appointment with a doctor by using the calendar function to choose available time slots in the doctor’s schedule.
- Real-time visits. Make patient-doctor interaction fast and convenient through video and audio calls. High-quality video is essential for doctors to see and evaluate the signs and symptoms of illnesses and diseases. If your budget allows, add a video conferencing real-time feature for more effective medical examinations.
- Communication. Besides video or audio call options, improve the user experience through one-to-one messenger implementation and share photos and other files using a safe and reliable connection.
- Geolocation. Telehealth services enable patients to overcome barriers to healthcare and get the necessary treatment while staying at home. Geolocation is needed to allow patients to find pharmacies and hospitals nearby and map out their routes.
- Payments. The app should offer a payment option so that patients can pay for their visits. App developers need to provide multiple payment methods to allow patients to choose the most appropriate way of payment: credit card, debit card, insurance coverage, employer coverage, or coupons.
- Push notifications. Patients may get notifications of an appointment approval or rejection. This feature may also remind users about upcoming visits.
- Ratings and feedback. Ensure that the app users can search for the best specialists considering real users’ feedback. Develop a rating and reviews section where people can share their opinions about consulting doctors. It would be great to put the best-rated specialists first in the doctors' listings.
- Insurance plan. Give your users an option to attach an insurance plan to their profiles. Patients can keep everything in one place and automatically have their bills forwarded to their insurance company.
Doctor’s telemedicine app features
The telemedicine app for doctors should be easy to use and provide clear navigation. First of all, doctors choose whether to accept or decline a patient’s request. If they have time, they create a visit where examination, diagnosis, and a treatment prescription occur. If the patient doesn't have any questions, they can simply end the call or schedule a follow-up visit if needed. Let’s consider the main functionality for this app:
- Doctor’s profile. The profile is a doctor’s calling card helping patients decide if they want the specialist to treat them. In addition to general information like name, address, photo, and specialization, it’s also wise to provide their education, experience, and credentials details. The more relevant data the doctor will have on their profile, the more patients they will have to make a more informed decision.
- Scheduling and calendar. A calendar within the app will allow a doctor to make available time for remote consultations visible to the patients. When a patient requests an appointment, and if the doctor accepts it, this time is automatically set as unavailable for others to view in the calendar.
- Video or audio session recording. Empower doctors to control the quality of the service using video and audio consultation recording. This feature will be helpful both for patients and doctors in the event of treatment questions or other possible misunderstandings.
- ePrescription (eRx). Ideally, telemedicine applications for healthcare providers should be integrated with pharmacies. Having quick access to a list of pharmacies with needed medications, doctors would be able to recommend the closest locations with a range of relevant prices. Doctors will also appreciate writing a prescription in the app and sending it to the pharmacy electronically. This functionality also helps to keep all medical history in one place.
- Electronic medical records integration. With an integrated Electronic medical records system, doctors will have access to patients’ medical records and lab results in real-time. Doctors will consult with a patient’s health information contained in their profiles, previously filled forms, hospital database, and other sources.
- Analytics. App developers should consider the implementation of dashboards for doctors that will allow them to adjust their prescriptions and treatments if needed.
Tech stack for telehealth app development
When answering the question of how to build telemedicine app, do not forget about technology. Onix’s professionals suggest utilizing the following technologies for improving the usability of a telemedicine application:
- Platform compatibility and codebase considerations mean that you may need to choose the platform - iOS, Android, and/or web - and the corresponding programming languages: Swift, Java, or React Native.
- EHRs integration is necessary for real-time digital records security and instant availability.
- Video calling APIs for advanced video calling experience, including encoding and transmission and video and audio by automated optimization.
- Chat and messaging APIs for efficient communication between patients and doctors using advanced in-app chat features like threads, typing indicators, and read receipts.
- Developing reliable high performance and scalability will enable automating the processes by an infrastructure-as-code approach.
6 steps for building a telehealth app: challenges and tips
Well, it's time to learn how to build a telemedicine application.
Start with a discovery stage
The first step is to gather project requirements and prepare a work plan. This is what a discovery phase is about, in a nutshell. Your project success depends on how clearly you define goals, accurately estimate a project, and define future steps.
The product discovery stage allows your outsourcing development vendor to determine project complexity and what functionality to implement, test the market viability, set deadlines, select needed technologies, define expectations on budget, and plan a project.
For example, at Onix, our specialists write documentation that includes all the key project details to implement it correctly. As a result of the product discovery phase, we can organize smooth and timely product development and stay on the same page with our clients.
Select the required platform
Before you start coding and designing your telemedicine app, it's vital to do deep research and decide on which platform your app will run.
There are three common app development approaches you can choose from to build a telemedicine app:
- Native app development is suitable for building a telemedicine app that will run on a specific platform (iOS or Android). This approach involves using specific technologies and tools for a particular platform.
- Cross-platform app development is the creation of software applications that are compatible with multiple mobile operating systems. To put it simply, this approach allows developers to create a single codebase that works simultaneously on multiple platforms.
- Web app development involves creating apps that use remote servers and run on a mobile device. This is a great way to be available for mobile and desktop users.
Ensure friendly and intuitive UI/UX
Having a great idea isn't enough if your design doesn't satisfy users' needs and expectations. The main purpose of UI/UX in telemedicine apps is to make all the required information available and to facilitate navigation for both patients and medical professionals.
Engage UX/UI designers that specialize in creating effective and easy-to-use interfaces for the healthcare industry. An expert will adjust the logic, navigation, and layout to all target users’ preferences and needs to ensure optimal user experiences.
Below we share some practical design tips that help achieve results:
- Easy-to-follow onboarding. Most of the medical staff, especially older generations, isn't tech-savvy enough. So, when designing a telemedicine app, it's crucial to ensure a straightforward and intuitive onboarding process. For example, you can show users valuable tips navigating users through the app to know core features. Comprehensible onboarding procedure improves users' experience and engages them since you show your care from the very beginning.
- Usability. Poor usability of telemedicine app lowers the chances that this product can thriving despite its revolutionary idea in healthcare. Keep simplicity and ease of use as your most significant goal. Ensure all necessary elements are available on the dashboard and all buttons and icons are obvious and self-explainable. This clarity enables healthcare providers and patients to quickly solve their problems without a long search for the required feature.
- Modern UI. Use a pleasant color palette, appropriate button sizes, easily readable fonts, the position of components on a screen to strengthen the UX. Don't forget to keep in mind your corporate style and make sure all design elements match your specific brand.
- Personalization. Each patient is different, not only in terms of medical history but also in preferences and personality. Understanding users' needs and goals provide the most relevant user experience. Personalization is a great way to make your product unique and valuable. For example, Orlando Health leverages patient data to offer personalized communication to new moms. The new mothers can pick a preferred track to focus on caring for the newborn and receive personalized emails/notifications addressing their queries.
Pay close attention to security
Security is paramount, especially in the healthcare industry, since it uses patients' private data. Jusy one security issue can ruin your reputation, and your customers will soon leave. Some best practices can keep your app security at the highest level. So, here they are:
- High-level authentication. SMS passwords are not enough to provide a proper security level. It's better to integrate several technologies. For example, you can apply multi-factor authentication (voice, face, and fingerprint recognition) or ask users to reset their passwords every two months. Moreover, it's better to limit the number of login attempts to avoid account hacking or information leakage.
- Restricted access to an app. To reduce data vulnerability, provide access to the patients’ data only to the authorized workers.
- Data encryption. One of the most essential steps in developing a secure telemedicine app is to encrypt data. Encryption algorithms encode data into ciphertext, hiding the actual content. There are such popular encryption methods as hashing, key derivation functions, signatures, and algorithms as Twofish, AES, RSA.
- Reliable data backup. To prevent the loss of electronic health information during some operations with data, it's vital to regularly back up your data. In case of data loss, data backup allows you to restore all the data quickly.
- Regular testing. Test, test, and test. You should be concerned about your app's security at every stage of the development process. Make sure you test every corner of the telemedicine app to ensure a high level of protection and avoid security problems in the future. To do this, QA specialists run penetration tests to simulate attacks for catching all security flaws and vulnerabilities.
Ensure compliance with all regulatory requirements
Well, if you’re serious about developing a telemedicine app, your next step is to be aware of local legal compliances and meet them. The Onix team has vast experience in healthcare app development. We know how to ensure your medical app complies with all legal requirements of local policies in which it will operate.
Let's consider the most common regulations your telemedicine app has to comply with:
- HIPAA (meaning Health Insurance Portability and Accountability Act of 1996 in the USA). It governs the management, storage, and transmission of protected health information (PHI). Since September 2013, all doctors, hospitals, insurers, and other entities that deal with PHI have been obliged to follow HIPAA guidelines to ensure compliance.
- General Data Protection Regulation (GDPR) is a healthcare regulation in EU law that requires tight security measures to govern the use of medical technologies and clinical assets.
- The Personal Information Protection and Electronic Documents Act (PIPEDA) is a Canadian law that sets the ground rules for how businesses collect and handle personal information in the course of commercial activities across Canada.
- The Interstate Medical Licensure Compact Commission (IMLC) creates a streamlined process for obtaining licenses for physicians seeking to practice medicine in multiple IMLC states. This legislation comes in handy to reduce physician shortages, especially in rural and underserved areas.
Consider APIs you can implement into your telemedicine app
There are ready-made APIs you can easily implement into your telemedicine app to reduce development time significantly. Let’s take a closer look at some popular ones:
