Compliance for healthcare apps: local and international guidelines

Healthcare apps process a great amount of sensitive data, comprising protected healthcare information. Therefore, these apps must comply with international and local standards for protecting personal data. The prominent medical app standards include the following:

  • HIPAA. The standard protects transmitting, recording, and keeping PHI. The standard is mandatory for apps operating in the United States.
  • HiTECH. It supports HIPAA and advances healthcare services and care coordination.
  • CCPA. Being a United States standard, it regulates the collecting, processing, and deleting of personal information.
  • PIPEDA. This standard was adopted in Canada, securing users’ data stored in healthcare apps.
  • GDPR. These rules protect personal data in the European Union.
  • DPA. This act of the United Kingdom supplements GDPR and protects personal data.

Healthcare app features

Let’s look at functions that make such apps helpful for users.

Core health app features

There are some basic functions for your app.

Doctor profile lookup. With this feature, patients can look through the physician’s credentials.

Notifications and reminders. They help users take medicine on time, and remind patients about appointments.

Appointment booking. This feature enables doctors and patients to pick, modify, or cancel appointments. It saves time for the scheduling process.

Video conferencing. This function helps doctors see patients and offer them remote treatment.

Symptom checker. It enables patients to verify typical symptoms with the app and receive possible diagnosis.

Chatbots. Regarding disease conditions, chatbots with AI can determine the treatment actions for a patient.

Integration with electronic health records (EHR/EMR). Access to health history data with an app allows physicians and patients to see their data immediately.

Integration with medical devices. Data gathered by medical devices help doctors to define the treatment. Also, when people see the data on their devices, they better understand their health condition.

Prescriptions and pharmacy lookup. The electronic prescription feature enables doctors to make and send prescriptions to patients using the app. These prescriptions show the needed dosage and medicine clearly.

Payments and billing. These functions enable patients to pay for consultations, visits and services provided by doctors.

Health education. With this feature, patients can access broad information on health, and as well as doctors, get an education.

Next-generation features

By implementing the next-generation features to your app, you can significantly improve user experiences.

Let’s consider the trends for health apps.

Interoperability. It means that a healt app can work on diverse devices. So this means that patients will be able to get medical care remotely if they need it.

Remote control of patients’ health. Present-day technologies improve the process of treatment through remote interaction. Thus, people receive medical help without leaving their apartments.

Telemedicine. The telemedicine market is forecasted to reach about $460 billion by 2030.

Due to the online sharing of information, individuals do not have to visit a hospital physically. This saves doctors’ and patients’ time. Also, critical patients get consultations faster.

Medical equipment integration. Thanks to these integrations, doctors can access the latest patient health data.

Gamification. Gamification is an approach to using game techniques in non-gaming apps. This approach assists users in achieving the set goals. So they keep more involved with the app.

Artificial Intelligence (AI). AI assists doctors in diagnosing patients. It gives health advice to patients and offers virtual nurse assistance. Apps with AI comprise engaging games and events. AI is also applied in chatbots that assist in coping with interpersonal issues.

Virtual Reality (VR). VR technology is a technology used for occupational and psychological treatment. By applying this technology, people navigate through digital environments and do specific tasks that aim to treat different diagnoses. For instance, VR in the Floreo app helps to educate patients with autism spectrum disorder on typical social interactions.

Virtual waiting rooms. This virtual waiting room for patients can be accessed via the health app installed on mobile devices. Such waiting rooms help minimize the risk of spreading diseases.

Internet of Things (IoT). Wearable devices are the best examples of implementing IoT. They collect physical data from people, for example, from patients with dangerous to lives diseases. Wearables also assist in counting calories, water intake, heart rate, and so on.

Blockchain for EHR. EHRs have been a priority in healthcare since they hold valuable patient data. Blockchain technology helps track health records and prevent mistakes. It is crucial to select the appropriate treatment.

Revenue models for health apps

Mobile health apps have a few revenue sources. Here, we have gathered the most popular monetization models, but you can have a full understanding of them in this article: 10 Best Marketplace Monetization Strategies to Succeed.

Also, keep in mind, that you can combine the revenue models described below.

Freemium model

The freemium model is great for engaging users as you offer your health app for free. Still, you need to provide advanced paid features to generate revenue. Payment can be one-time or subscription-based.

The prominent health apps applying the freemium model are Lifesum and MyFitnessPal.


This monetization approach is a popular choice as it takes the least effort to include it. But keep in mind user experience should be a priority. So, you should offer personalized ads and make them as useful for visitors as possible.

The prominent health apps using in-app advertising comprise MyTherapy and K Health.

Subscription model

Applying this model, you can charge a monthly, quarterly, or yearly fee for using your app. To keep users engaged with your application, offer updates with new functions. and Teladoc are successful apps that apply a subscription model.
