Trinktagebuch by Deutsche Hauptstelle für Suchtfragen e.V. (DHS) is a free app for Android that helps document your alcohol consumption. With this app, you can set your own goals, find out if your alcohol consumption is okay, and get support if you want to drink less. The app provides suggestions and tips to help you avoid risky alcohol consumption. You can recognize the alcohol content of different alcoholic drinks, make entries in your drinking diary, set and change your personal consumption limit, and compare your consumption habits with the limits for relatively low-risk consumption.

You can also retrieve your entries as graphics (daily, weekly, or monthly consumption), create notes to motivate you to drink less, find competent contacts, and expand your knowledge of alcohol-related topics. The app also helps you find contacts and resources for self-help groups, counseling centers, and specialized clinics in your area. However, it is important to note that this app does not replace the need to visit a doctor, self-help group, or counseling center. It is intended to help you check the amount and frequency of your alcohol consumption and reflect on your own drinking behavior.
