Brim – Water Tracker
Smart hydration based on your weather, activity & sleep
Most water apps give you a flat "8 glasses" goal regardless of your day. Brim calculates your daily target dynamically — it factors in temperature & humidity (WeatherKit), your workouts and steps (Apple Health), and sleep. Hot day after a run? Goal goes up. Cold rest day? It comes down. Free to download, with a Pro tier ($4.99/year) for home screen widgets and streak tracking. No account needed, no data leaves your phone.
Hey PH! I'm Juraj, the maker of Brim.
I built this because every water tracker I tried gave me the same flat goal regardless of the day — 8 glasses on a hot day after a 10k run, same as a cold rest day on the couch. That never made sense.
Brim reads your actual day from Apple Health (steps, workouts, sleep) and WeatherKit (temperature + humidity) and adjusts the target in real time. Hot summer run day: maybe 3.5L. Quiet winter day: 2L is fine.
Free to use. No account, no cloud sync by default. Happy to answer anything about how the adaptive algorithm works!
