Reminder timer to drink water

Can we add functionality in the app that would remind the user to drink water? I'm currently using my own timer to do that. However I recommend the following

1. User sets a water timer to go off every hour in Chronometer

2. Timer pops up with water diary entry popup window.

3. User entera how much water is consumed and enters clicks edit. The entry is saved in the current days food diary.

The timer function could be designed as generic meaning it can be used not only for water but by other reminders such as supplements.

Thanks
