Types of Healthcare Applications

Healthcare applications drastically vary from type to type, which also impacts development. Some apps do not need to go through medical certification while applications for doctors, such as patient monitoring solutions, do require compliance. In this section, we will look at three main types of healthcare apps in more detail.

For Patients

Healthcare applications for patients encompass a large part of the market and include online counseling, therapy, pill management, telemedicine, fitness, yoga apps, hospital apps for patients, etc. For example, telemedicine application development makes it possible to connect patients with doctors and allows them to gain more control over their healthcare. This is especially important for people who live in remote areas with limited access to physical hospitals or patients with disabilities that cannot easily visit a doctor at any time. Telehealth solutions include video and audio calls, chats, and other forms of communication that cater to the needs of the patients.

For Providers

Healthcare providers like hospitals and clinics require advanced diagnostic systems that reduce the number of erroneous diagnoses and treatment plans. Using technology like machine learning, such solutions can help physicians make data-driven decisions and identify patterns. Hospitals also need medical team management apps that help them organize their work most efficiently. Scheduling in the medical sphere can get complicated due to long shifts and emergencies, and a management solution helps simplify this process for hospital managers. Finally, electronic health records have become commonplace in many countries and continue to deliver better results.

For Doctors

Applications that cater to doctors are vast and include educational platforms, networking apps, medical calculators, patient monitoring apps, etc. For example, educational apps can deliver new research and studies to help doctors stay up-to-date.

Patient monitoring

Remote patient monitoring applications allow physicians to track their patients’ vital signs, heart rate, pulse, cholesterol levels, and other parameters that might affect their condition. Using IoT devices and machine learning techniques, doctors can receive real-time patient health data and recognize abnormalities in their condition. As a result, physicians have vast amounts of information and utilize algorithms to increase the accuracy of their diagnostics.

Mental Health

If you would like to develop a health app that helps people gain access to mental professionals, you can opt for a mental health application. Solutions like Better Help connect patients to licensed therapists and psychiatrists and have online sessions. Doctors benefit from extra work and patients, whereas users get instant mental support at any time.


Getting an appointment at the doctor’s office used to require a phone call or email, which might be inconvenient to many people. Appointments also then need to be manually entered into the system, which always raises the risk of human error. Such applications allow physicians to optimize their scheduling and help users swiftly make an appointment with any medical professional in their location.


Especially patients with chronic conditions have to visit the hospital regularly to receive a new prescription. This places a burden on the patient who needs to take time out of their day to make the trip as well as on the doctor who needs to see the patient and write the prescription. Such solutions can automatically issue a new prescription when required and send it to the patient or pharmacy.

Drug management

Treatment plans often do not work because patients forget to take their medicine or exercise. This jeopardizes the entire process and decreases the chances of a successful recovery. Drug management apps remind users to take their pills, do a required exercise, refill their prescription or visit the doctor.

HIPAA compliance

The Health Insurance Portability and Accountability Act (HIPAA) is a data privacy law that ensures that healthcare organizations properly handle and store patient information. It regulates Public Health Information (PHI) that holds every aspect of patient data. If you want to develop a HIPAA-compliant solution, it needs to operate according to the PHI guidelines.

Here is a short guide to how to develop a healthcare app that adheres to HIPAA regulations:

  • Find an expert

If you lack expertise in this topic, it is recommended to employ an expert that will guide you through the processes and ensure full compliance.

  • Evaluate patient data

Make sure you only collect the data that is necessary for your business. Further, identify the data that qualifies as PHI and store all the PHI information that needs to be preserved.

  • Encrypt your data

To avoid privacy and security breaches and data leaks, use best practices to encrypt patient data and keep it safe.

  • Test your app for data security

Run tests on your application after every update. Make sure to include experts to ensure the documentation is relevant and tests are correctly performed.

Other privacy laws

Depending on the location of your target audience, you might also need to comply with the data privacy laws of other countries. For example, if you operate in the EU, you must comply with GDPR; in the UK, you need DPA, and in Canada, PIPEDA. Research the privacy laws and regulations in the target location and adhere to them to avoid financial and legal restitution.

Multiple devices and channels

Plan the required ecosystem of mobile devices in advance and consider whether your app will be likely used on a smartphone, tablet, laptop, PC, or wearables. For example, for quick access to information, users mostly prefer smartphones, whereas, for more in-depth research, they will probably use a tablet or laptop.

Thorough testing

Healthcare apps need rigorous testing like no other mobile solutions. These applications hold sensitive patient data, including financial information, and exposing it to people with bad intentions can lead to serious problems. Launching a solution without sufficient testing can cost you your reputation and put heavy monetary burdens on your company.

Accessibility and inclusivity in design

Inclusivity has been an emerging trend in multiple app development ventures, but it has a different meaning for the healthcare industry. These apps are more likely to be used by people with disabilities that require additional assistance. Make sure your product is accessible to people with various impairments and disabilities.
