Detoxer: An alcohol reduction app to help you drink less or quit. Whether you want to cut back or stop entirely, Detoxer is built for the hard part: the craving, the slip, and the next day. You don't need another lecture about drinking. You need something that shows up when the urge is loud, the night is long, and "just one" feels inevitable. ◆ WHY DETOXER Most apps count days and go quiet when it gets hard. Detoxer stays with you in that moment. See your streak grow. Proof you're changing. Open SOS when the urge hits. Guided help in about 90 seconds. Slip? Restart clean. No shame spiral. No "I failed so I'll delete the app." ◆ TODAY. Your day count, your why Wake up to a simple home for your progress. Check in. Remember why you started. Keep the streak alive, one honest day at a time. ◆ SOS. Help for the moment that matters When a craving arrives, don't white-knuckle alone. Tap SOS and get a short, focused tool for right now, not someday. It gives your mind somewhere else to go until the urge passes. ◆ RESTART WITHOUT SHAME A slip isn't the end of the story. Detoxer treats relapse as part of the path: reset the count, keep your dignity, keep going. ◆ MADE FOR REAL LIFE Personalized onboarding in about 3 minutes. Built for people who want to cut back or quit, not for clinical diagnosis. Light and clear, so opening the app feels like progress, not punishment. A clearer tomorrow starts with one day. ◆ DISCLAIMER Detoxer is a habit and motivation tool designed to support drinking less or quitting alcohol. It is not a medical device and does not provide medical advice, diagnosis, or treatment. It is not a substitute for professional care.
