What you get

Designed around how you actually drink.

Most water apps push the same goal on everyone. Brim adapts to your body, your activity, and the glass in your hand — then quietly helps you keep it up.

Personalised daily goal

Calculated from your weight, age, gender and activity level. Updates as your life does.

Gentle reminders

Nudges throughout the day on your schedule. Quiet at night. Never pushy.

History & streaks

Daily, weekly and monthly charts. Build the habit, watch the line climb.

Any glass, any size

From a 200ml espresso cup to a 1L bottle. Tap to add. Hold to remove. Done.

Beautifully simple

Animated bottle. Haptic feedback. Light and dark themes. Designed to feel calm.

Private by default

No account. No tracking. Your data lives only on your device — never sent to any server.

How it works

Three taps to a healthier habit.

Tell us about you

A short onboarding asks for your weight, age, activity level. We do the math.

Drink as you go

One tap on the bottle = one glass added. Hold to undo. Reminders nudge if you fall behind.

Watch yourself fill up

The bottle animates as you hit your goal. Streaks build. Habits stick.
