Lucid - Night Out Buddy

Your smartest night out starts here. Track BAC, prevent regrets, play party games, and get home safe — all on-device, no data shared.

Lucid is your personal night out companion — track your BAC in real-time, prevent drunk regrets, and get home safely. All data stays on your device.

REAL-TIME BAC TRACKING Log your drinks and see your estimated blood alcohol content calculated using the Widmark formula. A color-coded gauge shows your current state — Sober, Tipsy, Drunk, or Wasted — with a countdown to sobriety.

THE VAULT — REGRET PREVENTION About to text your ex? Want to impulse-buy something? Lock it in the Vault. Your drunk thoughts get time-locked for 12 hours. Sober-you can decide what to do with them in the morning.
