Best water tracker apps in 2026
For a water tracker on Android with no ads, no account and no in-app purchases listed, with reminders that can ring like an alarm, SipLog. For a standalone Apple Watch app, widgets and Apple Health sync, WaterMinder. For a playful tracker with challenges and characters to collect, in 22 languages, Waterllama. For growing a plant as you drink, Plant Nanny. Full breakdown below.
How we picked: we read each app’s own App Store and Google Play description for how reminders work, whether it needs an account, ads and subscriptions, and Apple Watch support. None of these apps is a medical device, and they say so.
A water tracker with no ads and no account
SipLog logs water and other drinks in a few taps, with common drink types or your own. You set your own daily goal instead of a fixed target, and reminders come as regular notifications or in an alarm mode when you need something harder to miss; both run locally on your phone. There is no account, login or server: drinks, goals, history, streaks and optional drink photos stay on the device, and you can export or erase them. It says it uses no ads, analytics or third-party tracking, and it works in English, Spanish and French, with a dark mode.
On your Apple Watch
WaterMinder sets a goal from your body weight or your own number, shows how full you are visually and in percent, and has a standalone Apple Watch app, Home Screen and Lock Screen widgets and Apple Health sync. Waterllama also has an Apple Watch app, widgets and Apple Health sync, calculates a goal from your weight, activity and weather, and tracks more than 150 common drinks.
A tracker that makes it a game
Waterllama adds challenges, hydration tips and more than 140 characters to collect and fill up, with streaks and monthly recaps. Plant Nanny grows digital plants as you drink, in three difficulty levels, with a widget and Apple Health sync. For other daily habits, see habit trackers.
