About Water Tracker - Drink Log
Stay hydrated, the smart way. Water Tracker helps you build a sustainable hydration habit. With body-optimized goal calculation, per-drink water conversion, and cycle-aware recommendations, it's designed to fit your real body — not a one-size-fits-all number. --- Key Features --- ■ One-tap logging Quick buttons for water, green tea, coffee, barley tea, miso soup, and more. Check today's intake at a glance from the home screen widget. ■ Body-optimized goals Your daily target is calculated from your weight and activity level — not a generic "drink 2 liters" push. ■ Per-drink water conversion Coffee and beer are auto-adjusted for their diuretic effect. Coefficients for tea, milk, sports drinks, and more are built in. ■ Cycle-aware recommendations Menstrual, follicular, ovulatory, and luteal phase — hydration needs are automatically adjusted. A feature for women that no other app offers. ■ Apple Health integration Every drink is automatically written to Apple Health, keeping all your wellness data in one place. ■ Home & Lock Screen widgets Progress ring plus recent records — see your status without opening the app. ■ Smart reminders A gentle nudge two hours after your last drink, only between 9 AM and 10 PM — no midnight interruptions. ■ Backfill up to 12 hours Forgot to log that morning coffee? Add records with the exact time. ■ Custom drinks Soy milk, protein shakes, herbal tea — register your own with custom conversion coefficients. ■ iCloud sync Your records sync automatically between iPhone and iPad. --- Perfect For --- ・Building a daily hydration habit for skin & wellness ・Anyone tired of the arbitrary "2 liters a day" rule ・Aligning hydration with your menstrual cycle ・Coffee & tea drinkers who want accurate water counts ・Users who want everything synced to Apple Health --- More --- ・Full dark mode support ・16 languages supported ・iCloud sync ・Privacy first: data stays on your device and iCloud --------------------------------- Sage Apps Series A collection of iOS utility apps designed for simplicity and ease of use.
