About

Saketracker

Features
Read full description

Saketracker is a single-purpose iOS app that lets you log every drink with one tap and tracks daily / weekly pure-alcohol grams plus alcohol-free (AF) days you explicitly confirm. "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 and want your drinking records kept 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", or use the dedicated button to choose date, 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 - Home Screen Widget (Small) — one tap to log from your home screen - Siri / Shortcuts ("Log my most frequent drink in Saketracker") - 7-day record history ■ Pro (one-time purchase) unlocks - Unlimited custom drinks - Live Activity + Dynamic Island for today's / weekly totals on the Lock Screen - Lock Screen Control + Action Button integration - Monthly calendar heatmap of drinking patterns - Weekly / monthly stat charts - Multi-serving entry (×2, ×3...) - Full history + CSV export - Medium / Large home screen widgets ■ What we focus on - Free to start (37 presets + up to 3 customs) - No sign-in. No accounts. - Drinking records stay on your device. Optional crash diagnostics never include your entries. - No subscriptions. Pro is a one-time purchase only. - No ads. ■ Intentionally NOT included (important) - We do NOT estimate blood alcohol concentration (BAC) and do NOT predict when alcohol clears your body. This app cannot be used to judge fitness to drive. Driving under the influence is illegal. - We do NOT provide medical advice, liver-function evaluation, drug-interaction guidance, or pregnancy-related drinking guidance. Please consult a medical professional. ■ Requirements iOS 18.0 or later (for Live Activity / Lock Screen Control / Action Button APIs) ■ For people under the legal drinking age Saketracker is intended for adults at or above the legal drinking age in your country. Please follow local laws and guidelines.

Verdict

The call

The clearest difference is in-app purchases: まるけん at none against Saketracker's 1. まるけん also leads on iOS requirement (14.0 vs 18.0). Saketracker's advantage is update cadence (every 4 weeks vs every 3 months). On price, ads and device support there is nothing between them.
