Hydration, made fluid. Most trackers turn a glass of water into paperwork. IdroFlow does the opposite โ€” it gets out of the way. One tap, and the day moves on. The whole app is built from restrained glass surfaces that let your progress show through, with motion that behaves like the thing it is tracking. Clear, quiet, and calm enough to keep using on the days you would rather not think about it. A tap is the whole ritual Your usual drinks are waiting where you left them. Tap one and it is logged โ€” no forms, no sliders, no arguing with a keyboard. Water, coffee, tea, or something you named yourself, in the amount you actually drink. Logging should cost you nothing, so it costs you a second. The numbers tell the truth Not every drink hydrates the same way, and IdroFlow does not pretend otherwise. A 350 ml coffee counts for what it really contributes, and the arithmetic happens on screen where you can see it. One honest goal, instead of a dashboard to manage. Reminders with a sense of timing Choose the hours that suit your day and they stay out of the rest of it. Reach your goal and they stop until tomorrow. Nothing buzzes just to prove the app is still installed. Where you already are Log from Apple Watch with the Digital Crown, with or without your iPhone nearby โ€” including after a workout, when it matters most. Keep today on your Home Screen and Lock Screen, or just ask Siri. Water and sparkling water flow through to Apple Health, and everything you log follows you between devices through your own iCloud account. New in 2.0 Today, Timeline and Insights have been rebuilt around one idea: hydration, made fluid. The same calm surface across iPhone, iPad and Apple Watch. Insights read the rhythm of your recent days and tell you what actually changed โ€” not what a chart looks like. IdroFlow Plus Custom drinks with your own names, colors and hydration values. Up to eight quick-add buttons. Adaptive reminders that follow how your days usually go. The complete set of insights. Extra widgets and Watch complications. And, if your device supports it, logging from a photo or by writing what you drank โ€” both use Apple Intelligence, and need a compatible device, an up-to-date iOS and a supported language. No ads, and no account to create. What you drink stays yours โ€” it lives in your own iCloud and Apple Health, and nobody at IdroFlow can see it. IdroFlow Plus is available as an in-app purchase.

About

Brim

Read full description

Brim is a water tracker with no charts and no scolding. Your day is a glass, and the water rises as you fill it. Tap what you drank โ€” 250 ml, 500 ml, whatever you set โ€” and the water rises to meet it. That's the whole interaction. One tap, one second, and the level is the answer. The screen is the readout. From arm's length you can see where you are without reading a number, because the waterline is the number. Digits are there when you want them, at the top, in a size you can read across a room. A faint dashed line marks where the day's clock has reached. If you're ahead of it, the line is underwater and you never see it. That's the only pacing signal in the app, and beating it means seeing nothing at all. Reminders stay quiet when you're ahead. Drink a large bottle and the next few nudges simply don't arrive. Reach your goal and they stop for the day. Choose the hours you're awake and how often you want checking in โ€” gentle, steady, or often. A Home Screen widget shows today's level at a glance, with buttons to log a drink without opening the app. Ask Siri, too. History keeps every day you logged, with a daily average and a count of days you reached your goal. There are no streaks in Brim and there never will be โ€” a missed day is not a punishment. Millilitres or fluid ounces. Five water colors. Seven languages. Your day can start at 4am rather than midnight, so a late glass counts where you'd expect. Your water stays on this iPhone. No account, no sign-up, and none of your drinking data ever leaves the device. Brim is free, and shows one ad a day โ€” a single one, when you reach your goal, never while you're logging. One payment removes it for good. No subscription, ever. Brim counts what you tell it, against a number you chose. It doesn't give health advice and it never will. Built for iPhone.
