I wanna propose a hybrid app with functionalities that required image recognition. We can start from the simplest implementation like reading medicine info from an image(suggested by @mdsupport ) then may move to a higher level where we can make the app capable of extracting meaningful interpretation out of the medical monitor. Also, we can replicate the functionalities which are frequently used and require a camera(any operation which is easy with a mobile) to the app for easy access.
Another feature that I wanna propose is the ability to check the heartbeat with the help of mobile alone. This feature will be quite beneficial to people who face difficulty in commuting to clinics in my vision.
