Join the Drink Water Challenge

Six reminders a day, from 7 AM to 9 PM, to help you build a lasting habit.

Everyone knows they should drink more water. Almost nobody does it consistently. The reason is simple: thirst is a late signal, and busy days push it to the back of the queue.

Small sips, spread out

Instead of trying to drink two litres in one go, the Drink Water Challenge spreads it across your day. Six reminders at 7 AM, 10 AM, 12 PM, 3 PM, 6 PM and 9 PM, each asking for just one glass. Small, regular sips are easier on your body and much easier to remember.

Habits are built by repetition

A new habit forms when the same action happens at the same moment, over and over. By pairing a glass of water with fixed times, the challenge gives your brain clear cues. After a couple of weeks, many people find themselves reaching for water before the reminder even arrives.

Make it yours

Anyone can join the challenge for free and get all six daily reminders. On the Plus plan you can change the times to fit your day. On Pro you can also choose where the reminders arrive: in the app, on WhatsApp, or both.

Start today
