Have trouble remembering to drink water? You're not alone.

If you've been chronically under-hydrated you may not get the feeling of thirst regularly throughout the day. This makes it difficult to remember to drink water.

'Hydration' can help with this. You can use this application to set audio alerts at certain times throughout the day, repeating at given intervals. You can also keep track of how much water you've drunk in a given day so you can see how you're doing. (Eight 8oz glasses has been recommended often, but it depends on the person and their activity level).

'Hydration' lets you set the size of the water bottle you're using. The size you give is converted to a number of 8oz glasses. Every time you click the "+" or "-" on the main screen it will add or minus that many glasses. Also if you only drank, for instance, half your water bottle at one time but would like to track that progress simply move the slider bar on the main screen to the half way point and then press the "+" button.
