This was my favorite utility type app but suddenly its losing data. When I first installed it a couple months ago, it updated on iTunes & I lost our Dec- Feb sicknesses with that update & i had to start over. Ive been using it DAILY for the past 8 weeks for a chronic condition that has flared with increasing frequency, making me have to update notes / symptoms etc. from 1-3x a day. I entered todays note, symptoms, & pain scale at 4:15 & updated twice more & each time it lost the updates. Actually, each time I updated, I reentered the lost info with the update & each time it reverted to the first entered info. This affected the notes, pain scale, symtoms, & medication fields. Great concept & very useful but only if it works. And since this is regarding peoples health, it needs to be virtually flawless! It cannot have lost data! Correct the bugs & it will rate 5 .
