How and Why to Develop a Mobile Healthcare App[1]

4. Test your new healthcare app before launch

Medical apps should be easy to use, simple to understand, and most importantly, they should ensure high-level security and confidentiality of patient data (aka be compliant with HIPAA in the USA and GDPR in Europe).
Of course, any mobile app should be thoroughly tested before it goes live. However, mobile health apps have more development and testing requirements than other apps. It goes without saying that releasing your mHealth app without proper testing could have fatal consequences. 
So before launching your new health app on the App Store or Google Play, make sure your application is rigorously tested and ready to launch.
