ANDROID APP FOR MEDICAL DECISION MAKING . Prefer bids from US/Europe/Aus -- 2

I need a medical decision making app to be created. It has 12 screens. No online storage, all info is on the phone. You must be able to implement flawless logic, and this must work on all phones from 6.0 to 9.0. one screen has patient list, 1 screen has generated report , 10 screens are for data input. CODING FOR THIS APP NEEDS A LOT OF MENTAL SHARPNESS AND ALERTNESS SO THAT NO ERRORS ARE MADE , BECAUSE THIS IS FOR MEDICAL PURPOSES. THIS IS NOT A PROJECT YOU DO WHEN YOU ARE TIRED OR AT 2.30 AM. IF YOUR THINKING TENDS TO BE A BIT CLOUDY, THIS IS NOT THE PROJECT FOR YOU. Not for beginners. No bids from indiapak region please. BUDGET IS $250 not negotiable. I will provide UI.
