HungRecover: BAC & Recovery

HungRecover is a drink and recovery tracker for adults 21 and older. It uses the Widmark formula with standard metabolism rates (0.015/hr men, 0.013/hr women) to estimate your blood alcohol concentration from drinks you actually log, then maps your hours-since-last-drink onto a five-phase recovery timeline so you know what your body is probably doing right now. It is not a breathalyzer and it is not medical advice. It is a math tool that applies common physiology assumptions to your own inputs so you can understand hydration, rest, and recovery context. HOW PEOPLE USE IT Saturday night: tap the glass icon, pick a category (light lager, hard seltzer, herbal liqueur shot), adjust ABV, save. The home screen updates with an estimated BAC and a color-coded status pill — green for a lower estimate, yellow past one hour, orange past three, red past six. See how each logged drink changes the estimate before you keep going. Sunday morning: you wake up feeling rough. HungRecover already knows your last drink was at 1:30 AM and shows Peak Symptoms — the first recovery phase — with a reminder that each standard drink may contribute to losing roughly 120 mg of key electrolytes through diuresis. Log a glass of water; the phase transitions through Rough, Stabilizing, Recovering, and Countdown Complete over the day. Tuesday after work: open history to see last weekend in context. Total drinks, estimated peak BAC, estimated recovery window, and whether hydration caught up. The point is not shame — it is a real picture instead of guessing. WHAT IT DOES - Drink logging with type, volume, and ABV (generic categories, no trademarked names) - Real-time BAC estimate using Widmark (r = 0.68 men, 0.55 women by default, editable) - Five-phase recovery timeline driven by hours since last drink - Color-coded status band (green / yellow / orange / red) - Electrolyte tracker with approximate per-drink estimate (~120 mg) - Local history stored on-device via SwiftData — no account, no cloud, no server - Export My Data writes timestamped JSON - Delete All My Data wipes every drink, phase, and electrolyte record immediately FREE-FIRST ACCESS This first submission is free-first. Core drink logging, recovery estimates, hydration tracking, history, export, and safety tools are available without a purchase. Paid features may be evaluated in a later release only after purchase and restore flows are fully tested. PRIVACY Everything you log stays on your device. No account, no sign-up, no analytics tied to your identity. Uninstall or tap Delete All My Data to remove your records. A privacy manifest ships with the app. FOR ADULTS 21+ HungRecover is designed for adults 21 and older. An age gate at first launch enforces this. If you or someone you know is struggling with alcohol, call SAMHSA's free, confidential helpline at 1-800-662-HELP (4357), available 24/7 in English and Spanish, or visit samhsa.gov.
