Track your night. Share the story.
A social drinking session tracker — Strava for nights out.
Drunkva is a mobile-first, social session tracker for your nights out. You log drinks in real-time to build a live "confidence curve" that categorizes your night into six distinct stages: Baseline, Bullish, Ascend, Climax, Half-life, and Credits. When the night ends, you export a personalized, AI-captioned photo overlay (the "Morning Card") to share your peak stats with friends. On the platform, a real-time social feed lets you verify sessions with tagged witnesses, view confidence arcs, and "cheers" your friends' nights.
Responsive & accessible: Optimized for phones (320px–430px) with full safe-area inset support for notches, dynamic islands, and gesture bars.
Screenshots captured at 390px viewport. App is responsive across 320px–430px (mobile to tablet) with safe-area inset support.

Tech Highlights
- Implemented strict hydration mismatch fixes for native dark-mode (
color-scheme: dark) - Responsive viewport units (100dvh) prevent mobile browser zoom-on-scroll jank
- Safe-area-inset environment variables provide native notch + gesture bar support
- Uses Vercel Cron (
/api/cron/morning-card) for automated 10 AM notifications - Real-time visibility-state based polling to conserve battery while keeping social feeds alive
- Client-side offline synchronization queue using
idb - Morning card flow optimized: 2-step unified wrap-up + export (merged from 3-step design)
Recent Updates
- Peak confidence now decays from stored timestamps on read, so live views and exports stay consistent even after inactivity.

Drunkva tracks your night using a proprietary confidence curve algorithm that weights different types of alcohol against time.
| Drink Type | Weight |
|---|---|
| 🍷 Wine | +10 |
| 🍺 Beer | +12 |
| 🍹 Cocktail | +13 |
| 🥂 Spirit | +15 |
| 🥃 Shot | +18 |
Stages
- Baseline: 10% - 15%
- Bullish: 16% - 35%
- Ascend: 36% - 58%
- Climax: 59% - 82%
- Half-life: 83% - 92%
- Credits: 93% - 99%
How it works The confidence floor is hard-capped at 10% and peaks at 99% (because no one is ever truly 100% in control). Time decay kicks in if you stop drinking: after a 90-minute grace period, your confidence decays by 5% every 30 minutes.
The card always shows your peak — not where you ended up.
