Nice app.

It is a useful app for me but I would like to choose time (ex: I have to drink even at 3 a.m. when I sleep) and when I drink 30 min before the app says to do it, it doesnt change time and after 30 min I have to drink again.
Today Statistics graphic doesnt show any difference between days, even if i drink differently. Last 7 Days and Last Month (but I havent tried the app for 1 month) graphics doesnt show the glasses of water skipped, they continue to be all blue.
