About

Ondaya

Drink enough water every day โ€” without having to think about it. Ondaya reminds you to drink at the right moment, from the time you wake up to the time you go to bed, and stops as soon as your daily goal is reached. No nagging, and never a notification in the middle of the night. Your goal is calculated from your weight, and you can change it whenever you like. One tap logs a glass: 150, 250, 350, 500 ml, or any amount you choose. WHAT YOU GET โ€ข Smart reminders, only between your wake-up time and bedtime โ€ข Reminders stop automatically once you reach your goal โ€ข One-tap logging, with four quick amounts โ€ข A tank that fills as you drink โ€” your whole day at a glance โ€ข 7-day history, weekly average and goal streak โ€ข Millilitres or ounces โ€ข Light and dark theme โ€ข 12 languages โ€ข Works completely offline โ€” no account, no sign-up WHY IT MATTERS Mild dehydration is enough to blunt concentration, bring on fatigue and trigger headaches. The difficult part was never knowing that you should drink โ€” it is remembering to do it, hour after hour. That is the one job Ondaya does. PRIVACY Everything stays on your phone. No account, no sign-up, nothing to hand over. Free, supported by ads.
