About

SipFlow

Read full description

SipFlow turns drinking water into a tiny daily ritual with a friend. Remember the pocket pets of the 90s? Your droplet buddy is a tiny virtual pet that levels up as you drink water. Name it, take a sip, tap. It wobbles, splashes and smiles, and your day fills up one sip at a time. No measuring cups, no typing numbers. TAP AFTER EVERY SIP • One tap logs one sip, sized to you from your answers during setup • Undo in a tap if you pressed by accident • A gentle daily goal you can change any time A BUDDY THAT GROWS WITH YOU • 13 levels with a gift on every new one • Pet your buddy, dress it up with accessories and colors • Mini-games that never log water BATTLE WITH FRIENDS • Send a friend your code and see who drinks more water today • Get a nudge when a friend starts drinking or pulls ahead • Every morning, find out who won yesterday • No sign-up, just a name. Leave and delete your battle account any time STREAKS WITHOUT GUILT • A day counts as soon as you take one sip • New buddy colors at 3, 5, 7, 14 and 30 days in a row • Share a streak card with a friend • Missed a day? Just start again, no scolding ALWAYS AT HAND • Home Screen and Lock Screen widgets with a sip button • Live Activity on the Lock Screen and in the Dynamic Island • Friendly reminders at the hours you choose • A calendar of past days SIPFLOW PLUS Plus adds rescue days (two a month, so a missed yesterday doesn't break your streak), three more games (Lily Jump, Little Drops 2048 and Catch the rain), the Apple Watch app, Live Activity, coffee colors and the pink bow, and unlocks gift colors right away. Choose Monthly, Yearly (first week free) or Forever, a one-time purchase. Subscriptions renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel in Settings › Apple Account › Subscriptions. PRIVATE BY DESIGN No ads, no analytics, no tracking, no sign-up. Your data stays on your device; the battle shares only your name, your buddy and today's water with friends you add. SipFlow estimates intake from taps. It doesn't measure what you drink and isn't medical advice.
