No. Bleib Nüchtern is a companion, not a replacement for professional help. If you have heavy alcohol consumption or physical dependency, please consult a doctor. The app includes crisis hotline numbers for emergencies.
Cravings usually pass within 15–20 minutes. Bleib Nüchtern includes Urge Surfing, a technique to observe and ride out cravings without acting on them. The Toolbox also offers breathing exercises and a distraction list for acute moments.
The first step is awareness: track how much you drink and why. Bleib Nüchtern guides you through onboarding to clarify your goal. Reduce, pause, or abstain completely. Tools like a sobriety timer, AI companion Sam, and the Toolbox support you day by day. For physical dependency, always consult a doctor first.
After just 24 hours without alcohol, your liver begins to recover. After 1 week, sleep improves noticeably. After 1 month, skin becomes clearer and energy returns. The app’s Body Regeneration Timeline shows exactly what’s happening in your body, hour by hour.
Many people notice the first improvements within just a few days: better sleep, less bloating, more energy. After 30 days, mood significantly improves. After 90 days, the brain has measurably regenerated. Bleib Nüchtern shows you this progress in real time.
With 2 drinks a day at €3 each, you save over €2,000 a year. The built-in Cost Calculator in Bleib Nüchtern shows your exact personal savings, based on your own consumption data.
Urge Surfing is a mindfulness-based technique for handling cravings. Instead of fighting or suppressing the urge, you observe it like a wave that rises and falls on its own. Studies show this significantly reduces the likelihood of relapse. Bleib Nüchtern includes a guided Urge Surfing exercise in the Toolbox.
A relapse is not a failure. It’s information. Bleib Nüchtern doesn’t judge you: you can reset your timer at any time and keep going. Sam supports you without blame. Many people need several attempts before long-term change sticks. That’s normal and human.
Availability
The iPhone version is planned and follows after the Android launch.
