The water level rises as you log drinks through the day.

Why another water app?

Most hydration apps charge monthly for a glass of water, nag you with ads, or quietly ship your health data to analytics servers. Brimful was built as the opposite of all three.

Instead of subscriptions

Pay once, use forever

One purchase. No monthly fees, no premium tiers, no upsells — ever. Read why pay-once health apps are worth seeking out.

Instead of tracking you

Privacy by design

From "I should drink more water" to a daily habit

Brimful is built around the three things that actually change behavior: a goal you believe, logging that takes no effort, and progress you can see.

Set a goal that fits you

Your weight and activity level shape how much water you need — Brimful calculates an optimal daily target, or you set your own. Not sure what's right? Read how much water you actually need each day.

Log every drink in seconds

Tap a quick-add preset for water, coffee, tea, juice, or sparkling water — or your own custom drink. Hydration factors keep the total honest, and haptics make each log satisfying.

Watch the habit compound

The water level rises through the day, your streak grows through the week, and the 7-day chart shows the trend. Forgot yesterday? Backdate it — accuracy beats guilt.

One purchase. Yours forever.

Brimful is free to download, and the app's promise is simple: one purchase, no monthly fees, no premium tiers, no upsells — ever. No ads interrupting your morning glass of water, and no account required to start.

Questions, answered honestly

The short version: pay once, your data stays on your phone, and coffee counts (partially).

Is Brimful really subscription-free?

Yes. Brimful is free to download on the App Store, and its model is a single one-time purchase — no monthly fees, no premium tiers, no upsells, and no ads, ever. If you're tired of renting your health apps, here's what to look for in a no-subscription water tracker.

Where is my hydration data stored?

On your device. Brimful uses zero analytics, zero tracking, and zero cloud uploads. Your hydration habits are nobody's business but yours.

Do coffee, tea, and other drinks count toward my goal?

Yes. Brimful tracks water, coffee, tea, juice, and sparkling water, and each beverage has a hydration factor so your daily total stays accurate. You can also add your own custom drinks. Curious about the science? Read whether coffee counts as water.

How does Brimful know how much water I should drink?

Enter your weight and activity level and Brimful calculates an optimal daily water goal. Prefer your own number? Set a custom goal instead. Our guide to daily water needs explains the factors involved.

What if I forget to log a drink?

You can backdate entries you forgot to log, and edit or delete any entry. A 7-day progress chart and daily timeline keep your history accurate — missed logs don't have to break your record-keeping.
