iPhone
Log each drink with one tap; see today's and this week's pure alcohol g plus your AF day streak. No login, on-device only. Not for medical or driving-fitness use.
Saketracker is a single-purpose iOS app that lets you log every drink with one tap and tracks daily / weekly pure-alcohol grams plus your consecutive alcohol-free (AF) day streak.
"Was I drinking too much this week?" "How many AF days do I have going?" — for people who want to see the numbers and self-regulate.
■ Who it's for
- You want a number-based picture of your drinking habits
- You want to grow your alcohol-free day streak intentionally
- You hate ad-heavy apps and prefer one-time purchase over subscriptions
- You want no login, no cloud — all on-device
■ What "pure alcohol grams" means
Volume (mL) × ABV (%) / 100 × 0.8 — the standard formula used by Japan's MHLW (Kenkou Nippon 21, 3rd edition). It lets you compare beer, highball, sake, etc. on a single g scale. Example: 500mL of 5% beer = 20g.
Note: pure alcohol grams is not the same unit as US "standard drinks" (14g) or UK "units" (8g). Use the scale that matches your local guidance.
■ Key features
- 37 preset drinks (beer / highball / wine / sake / shochu / whisky / chuhai / non-alcoholic), including brand-named items
- Add custom drinks — alcohol g is auto-calculated from volume + ABV
- Tap to log "now", long-press to choose time and servings
- Today's total g vs. your daily target (default 20g, adjustable)
- This week's total + weekly target (default 100g) + AF day streak
