Sober Days is a private, offline-first Android app designed to support people who are quitting alcohol by making progress visible and offering practical help in high-risk moments. It tracks your last drink date and shows a large, clear “days sober” counter, estimates money saved based on your past drinking pattern, and celebrates milestones with professional blue-themed badges. You can optionally record why you want to get sober and include that reminder in daily notifications or risk-time nudges you schedule for your toughest hours. The app includes daily check-ins for craving, mood, and sleep, a calendar view, simple graphs for insights, trigger tracking with coping suggestions, and If–Then plans to prepare for difficult situations. It also provides a craving toolbox (timers, breathing, HALT, urge surfing, “play the tape forward”), a relapse-safe restart flow with a 24-hour plan, support contacts you can call or text with confirmation prompts, educational pages on early sobriety and alcohol’s effects, and a Get Help screen. Privacy features include PIN/biometric lock, logout, reset, and an optional discreet app icon/name.
