This app is based on studying the drinking behavior of volunteering participants with a goal of reducing their alcohol consumption. The study involves analyzing the alcohol triggers, consumption and actions taken under the influence of alcohol as reported by the participants by the means of reporting sections and periodic surveys in the app. This app also helps participants to monitor their blood alcohol content using a breathalyzer and encourages them to add and track their goals.
UNTETHER

Your phone doesn't own you. But how many times have you put it down and immediately reached back for it? UNTETHER is a quiet act of resistance against the impulse to reach for your phone. No distractions. No doomscrolling. Put your phone down, let the timer run, and rediscover life beyond the screen. HOW IT WORKS Hold the button until it says "LET GO" and release. Your screen goes dark, but the timer keeps running. The moment you leave the app or lock your phone, the session ends. THE RULES The Kill Switch: If you leave the app, check notifications for too long, or open anything else, the session ends. Integrity Protocol: Sessions under 10 seconds are void. Sessions over 12 hours are capped. Blackout Mode: For the hardcore. Zero grace period. All audio is blocked. Total presence. FEATURES SYNDICATES: Don't resist alone. Create or join a Syndicate (exclusive team) to compete on the leaderboards. GLOBAL LEADERBOARDS: Stand alone. Compete individually against users worldwide to see who has the true discipline to disconnect. RANKING SYSTEM: Earn titles based on your total time disconnected. Or, climb the Syndicate leagues with your teammates. OFF-GRID READY: Going camping? UNTETHER works perfectly without internet. "Off-Grid" sessions are saved locally to your history. Resist the pull. Be here now.
