3 main challenges of telemedicine app development

Accessibility and ADA compliance

One of the key challenges in developing telemedicine applications is creating a user interface (UI) that is both easy to use and provides the functionality that both medical professionals and patients need. Given that telemedicine apps are often intended to be used by the least tech-savvy audiences, it’s paramount to ensure that the interface isn’t cluttered and intuitive.

For example, aging populations, which are one of the most important target audiences for telemedicine apps, can be reluctant to use the app with unfamiliar UI elements. This is why telemedicine app development is not the right opportunity to showcase UI design sophistication and innovation. According to the former Apple accessibility expert, Cezary Tomczyk, the absolute majority of telemedicine apps lack accessibility features. In a nutshell, in the telemedicine app development context, usability is directly correlated with care quality.

There are a few key considerations to keep in mind when designing an app that is accessible for everyone:

Apart from these basic guidelines, we highly advise to follow Web Content Accessibility Guidelines (WCAG), which are internationally recognized.

Data privacy and security

The development of telemedicine applications poses a number of data security challenges. First and foremost, these applications must comply with the Health Insurance Portability and Accountability Act (HIPAA), which sets strict standards for the handling of protected health information (PHI). In addition, telemedicine apps must be designed to protect patient privacy and security, as well as to ensure the confidentiality of communications between patients and their healthcare providers.

One way to ensure data security in the development of telemedicine apps is to build encryption into every step of data transmission and storage. This means not just using secure connections and password protection, but also encrypting data at rest and during transfer. Another important aspect of data security is user education, as often data breaches are not due to technological failures but rather human error. Providing training on best practices for password management and data handling can go a long way towards preventing unauthorized access to sensitive information.

As we’ve outlined in our previous article on cloud-based EHR systems, collaborating with a reliable cloud system provider can significantly alleviate the risks associated with data privacy and security.

Regulatory approval

Developing a telemedicine app can be a daunting task, as it often requires obtaining regulatory approval from regulatory authorities like FDA. The process of obtaining such approval can be long and arduous, as it involves ensuring that the app meets all applicable safety standards. When it comes to telemedicine app development, it’s imperative to understand what regulatory approvals you need to obtain.

For example, a telemedicine app that is intended to treat, diagnose, cure or prevent diseases without being part of a hardware medical device can be classified as Software as a Medical Device (SaMD) by FDA. Understanding whether your software falls under SaMD is a nuanced matter that often calls for expert opinion from an experienced healthcare software developer.

In reality, even the simplest, general-purpose telemedicine apps are classified as SaMD. For example, apps that collect patient data in real-time for the development of treatment plans, or use built-in accelerometer or hear-rate monitor on a smartphone to diagnose certain conditions are classified as SaMD.

Most important features in your telemedicine app


Doctor profile

A doctor should be able to easily add his or her credentials, years and areas of expertise, and appointment availability. One of the most crucial features here is to integrate a rating system that will encourage doctors to provide better care and help patients to be more confident in the choice of medical professional. Also, it’s important to implement a reliable online document verification system. We advise to use a third-party API-enabled software for that matter.

Patient history

Clear, error-free, and easily accessible patient history is one of the biggest prerequisites for improved patients’ outcomes. Based on test records, prescriptions, treatment history, and other patient data, doctors have a much better chance at making accurate treatment decisions. If possible, we suggest integrating existing EHR system as it can significantly lower development time and costs.

Digital prescriptions

Prescription management system is one of the most important features in a telemedicine app. It allows doctors to issue prescriptions directly from the app, which can then be filled at a local pharmacy. This eliminates the need to go to the doctor’s office in person and wait for a prescription to be issued.

A prescription management system would be especially useful for telemedicine apps that are used for chronic conditions, such as diabetes or asthma. In these cases, it is important for patients to have regular access to medication in order to manage their condition, without having to go through the hassle of scheduling an appointment with a doctor.  

Appointment scheduling

Calendar integration and comprehensive scheduling appointment system is crucial. Ensure that patients can clearly see a doctor’s available time slots, can schedule appointment in as few clicks as possible, can easily reschedule if needed, and can be notified prior to the appointment.

Video conferencing

Secure and reliable video conferencing platform is at the heart of every value-adding telemedicine app. The platform has to be high quality, low latency, secure, and easily accessible by less tech-literate populations.

Given that telemedicine video conferencing implies the sharing of highly sensitive patient data, real-time video communication has to adhere to HIPAA. Instead of using conventional matching password method, we highly suggest to integrate biometric-based authentication methods like fingerprints or voice recognition.

External device integration

In many cases, to bring real value from a telemedicine app, it needs to be integrated with some sort of medical device like glucose meter, ECG patch, heart monitor device, or any other remote patient monitoring device. Such apps are considerably more costly to develop, more complicated in terms of regulatory approval, but can win over a narrower target audience and realize more revenue in the long-term.

Developing a telemedicine app step-by-step

  1. Figure out what problem you’re trying to solve.

The first step in any good software development project is understanding what problem you’re trying to solve. What need does your app fill? What are your users looking for? A telemedicine app could fill any number of needs, from providing on-demand access to primary care physicians to offering specialist consultation for rare conditions. Once you know what problem you’re solving, you can move on to the next step.

  1. Research the competition.

Before you start development on your app, it’s important to understand what other options are available to your potential users. What features do they offer? How do they solve the user’s problem? What are their strengths and weaknesses? Knowing what’s already out there will help you determine what features your app needs to have in order to be successful.

  1. Choose your platform

When it comes to selecting a platform for a telemedicine app, there are several factors to consider. First, it’s important to assess the demographic of your target user base and their preference for mobile devices. For example, Android tends to have a larger market share globally, while iOS commands a majority in the US. It may also be wise to consider whether web or desktop options are necessary, as this can expand your potential reach to individuals without smartphones.

Another consideration is the capabilities and limitations of each platform: for example, iOS offers strong privacy features and compatibility with wearable devices, whereas Android allows for more customization and greater global reach. Ultimately, it’s important to weigh all these factors carefully in order to select the platform that best fits the needs of both your users and your telemedicine service.

  1. Look into regulatory compliance

Regardless of the type of a telemedicine app you want to create, you need to ensure compliance with industry standards like HL7, data privacy standards like HIPAA, and standard operating procedures used for SaMD registration. Failing to comply with these regulations can result in fines and penalties, and become detrimental to a business as a whole. This is why we highly suggest working with experienced provider with an extensive background in developing regulatory compliant telemedicine apps.

  1. Build your app!

This is where the rubber meets the road; it’s time to start writing code and building out the features of your app. This phase of development is all about taking your vision and turning it into a working prototype that you can use to test hypotheses and gather feedback from potential users. We highly suggest to consider the aforementioned development challenges, especially those concerning UI, accessibility, and data privacy. Don’t worry about making the perfect product at this stage; the goal is simply to get something up and running so you can start collecting data.

  1. Test, test, test.

Before releasing your app into the wild, it’s important to test it thoroughly on both real devices and emulators/simulators. Make sure all the features work as intended and that there are no major bugs or crashes. This step is crucial; if your app isn’t stable, users will quickly abandon it in favor of a better-performing competitor.


Telemedicine is here to stay, and developing a telemedicine app is a great way for startups to enter this growing market. By following these simple steps—understanding what problem you’re solving, researching the competition, choosing your platform and development tools—you can build a successful telemedicine app that meets the needs of both patients and doctors alike. Good luck!
