Hydro Homie

Simple, private drink tracker with a filling glass, streaks and reminders
New in version 1.2
Reproducible, developer-signed release build.
Hydro Homie helps you drink enough, without getting in your way.

Log a drink with one tap, or dial in an exact amount with the wheel (10 ml steps). The glass on the home screen fills up as you go, and a short confirmation shows that your entry was saved.

Features
• Quick-add buttons for water, tea, coffee, juice, soda and more – every drink counts with its own hydration factor
• Amount wheel in 10 ml steps
• History with a two-week chart and a three-month calendar
• Daily goal, streaks and achievements
• Extra water for physical activity and hot or cold weather
• Optional drink reminders with a soft water-drop sound
• Home-screen widget for one-tap water logging
• Light and dark theme, English and German

Privacy
No account, no ads, no analytics. Everything stays in a local database on your device. The app is offline by default; only if you switch on the optional "Fetch weather automatically" setting does it ask for coarse location and load the current temperature from Open-Meteo (coordinates rounded to ~10 km). The app is free software (GPL-3.0).

Versions

Although APK downloads are available below to give you the choice, you should be aware that by installing that way you will not receive update notifications and it's a less secure way to download. We recommend that you install the F-Droid client and use that.
