I had a similar app with a generic name (Probably "Drink more water" or something). Thing is, reminders always came in a bad time and were also followed by a sound of water filling a glass. When this thing blasted in a business meeting it sounded like someone peed in my phone.
My usual question: When can I expect an Android version to check it out?
And good luck!
Some people seem to struggle with drinking a good amount of water per day...
I always keep two 2L bottles refrigerated and get through them both each day. I only started the habit since following 4 Hour Body a while back. It's a great habit to pick up and it's pretty easy to get into once you start.
For those that struggle... try this app :)
Wow, this is sexy.
Any chance of integration with Fitbit, etc.? They have a feature like this but I haven't used it much -- perhaps that problem was part of your inspiration.
