IyalSip makes staying hydrated effortless. Log a glass with one tap, set a goal that fits you, and watch your day fill up with a calm, animated water gauge. No account, no ads, no tracking. Your data stays on your iPhone. WHY IYALSIP • One-tap logging — 250 ml, 500 ml or any amount • An animated water gauge that fills as you drink • Home Screen, Lock Screen and Control Center widgets — log without opening the app • Apple Health sync, both ways, free • Drink history showing every entry and where it came from • Gentle daily reminders • Clean trends with a daily-intake chart • Light and dark themes, in 12 languages APPLE HEALTH, BOTH WAYS Water you log here appears in Apple Health. Water you log anywhere else reaches IyalSip through Health, so your total is complete whichever app or bottle you used. One glass stays one entry — nothing is counted twice. It's off until you turn it on, each direction switches separately, and it's free: syncing your own data to your own phone shouldn't be a premium feature. PRIVATE BY DESIGN No sign-up, no cloud, no analytics. Everything you log stays on your device. Health data moves between IyalSip and Apple Health on your phone only — we have no servers, so there is nowhere else for it to go. IYALSIP PRO — MONTHLY, YEARLY OR ONCE • Smart reminders, timed to the hours you usually go dry • Your rhythm: when you drink, your strongest hour and the stretch you skip • 30, 60 and 90-day trends • Advanced insights: streaks, weekly averages, goal-met rate and hydration score • Day-of-week patterns Logging water is free, always. Pro is available as a monthly or yearly subscription — yearly starts with a free week — or as a one-time purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage or cancel them in your App Store account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Download IyalSip and build a hydration habit that sticks — one sip at a time.
