Log a drink in one tap
Quick-add cups sized the way you actually drink, in millilitres or fluid ounces. Your daily goal adjusts to you, not to an average.
Reminders that fit your day
Gentle nudges across your waking hours, quiet when you want them quiet, and they survive a phone restart.
Drinks that aren't just water
Coffee, tea, juice, soda and more, each with its own hydration factor — so a mug of coffee doesn't count like a glass of water.
Streaks and challenges
Keep a run going, and take on challenges when you want a target bigger than today.
Your history, your numbers
Daily, weekly and monthly views that show where your intake actually falls apart — usually the afternoon.
Yours, on your device
Everything you log is stored on your phone. Sipster works fully offline, aeroplane mode included.
Free, and honestly free
Sipster's free version is not a trial and does not expire. Logging, your daily goal, reminders, four quick-add cups and the last 30 days of history are free for as long as you use the app, and nothing you have already logged is ever taken away from you if you stop paying. The free version is supported by ads.
What Sipster Pro adds
- Unlimited cups — free keeps four quick-add cups; Pro has no limit.
- Custom drink types — build your own drinks with their own hydration factors.
- Full history — free shows the last 30 days; Pro shows everything, forever.
- Insights — the weekly read on where your intake goes wrong.
- Every challenge — including the long-form runs.

Pro is available weekly or monthly. Prices are shown in the app in your local currency before you buy, and subscriptions are billed by Apple or Google, not by us.
A note on health
Sipster is a general wellness tool for keeping track of what you drink. It is not a medical device, it does not diagnose or treat anything, and it should not be used to manage a medical condition. Hydration needs vary with your body, climate, medication and activity — and drinking far too much water can be dangerous, which is why the app warns you rather than cheering you on. Talk to a qualified professional about the right intake for you.
