Aquifer - Drink Water

Aquifer shows your day as one band: hatched for what you drank, pale for what is still open, with a line marking now. One glance is enough — no arithmetic in your head.

Drink your goal. Count the days.

WHAT AQUIFER DOES

• A daily goal derived from weight, workouts and weather — or set freely
• Log a glass with one tap; three of your own sizes sit ready as quick actions
• Custom glass sizes with names, reorderable: glass, cup, bottle, thermos
• History by week with bars, the goal as a line, and the day as a list
• Streaks and a month grid: filled means goal met
• Reminders in your window and at your pace — goal met means quiet
• Log straight from the notification, without opening the app
• Apple Watch with two buttons, a complication and a wrist notification
• Home Screen and Lock Screen widgets
• Apple Health if you want it: write water, read entries from other sources
• Light and dark, English and German, millilitres or ounces

WHAT AQUIFER DOES NOT DO

No account. No sign-up, no email, no password.
No ads. Anywhere, ever.
No subscription. Every feature is open, permanently.
No data for us. There is no server. Everything stays on your device.
No nagging. Aquifer counts along instead of telling you off.

If Aquifer helps you, you can buy me a coffee. One-off, voluntary, and it unlocks nothing — there is nothing to unlock.

NOTE

Aquifer is not a medical device and does not replace medical advice. With kidney disease, heart failure or while taking diuretics, speak to a doctor first.
