DrinkWatch app for iPhone and iPad

Count your cost, calories and units on a night out. Impress your mates with this ultra-handy app that can track your alcohol intake for any drink. Simply enter your drink and let drink watch keep track.
The drink watch app can be used to just calculate the number of units in a drink but it can also be used to keep track of units consumed on a night out and give you real-time feedback on how long it takes for alcohol to leave your system.
This App can keep track of your spend, calories and units consumed - it can be very enlightening to what you actually put away on a night out! Unlike other Apps drink watch makes no judgement on how much you drink— it is a means for you to understand the amounts and to act as you see fit. If you choose to cut down then that is your choice, or perhaps you can use it as a gauge to let you know when you are safe to drive*
If you are over the limit it can even find you the closest taxi company and get you home safe.

How does it work?
A weak pint of beer has 2 units in it. In the UK to remain within the drink drive limit you can have around 1-2 pints. But not all pints are created equal – Ranging from 3.5% to 12.0%.
This App is not restricted in the amounts that can be entered unlike other similar Apps. You are not restricted by the values specified on picker wheels.
