I'm Done Drinking is a lifestyle app developed by Gothic Software, Inc. for iPhone users. The app is designed to help users track their sobriety by counting the number of days they have been sober and the amount of money they have saved by not drinking. Inspired by the success of their "I'm Done Smoking" app, the developers created this app to help users stay motivated and committed to their decision to stop drinking.

The app's main display shows the number of days since the user has stopped drinking and the amount of money saved by not purchasing alcohol. The display updates in real-time, providing a constant reminder of the progress made. The app does not have a reset button or a way to add a drink, assuming that the user is committed to staying sober. Overall, I'm Done Drinking is a simple yet effective tool for those who want to maintain their sobriety.
