Hello,

I also started an android app for medical purpose but unfortunately I didn't complete it.

I just wanted to say that whatever you create make it easier to use.The GUI should be simple that any person can easily use it,because the medical related applications can have so many options and that can make the application more complex to understand than use it.

Hope this will help.

Thank you

I am not very much interested in programming So cant help you 

Sorry dear
