Lup: Water Reminder

Lup turns your daily water goal into your whole screen. The more you drink, the fuller it gets. Tilt your phone and the water tilts, shake it and it sloshes, flip it and it flows upside down. • One-tap logging: 150, 250, 330 and 500 ml, or a custom amount • Smart reminders: only while you're awake and after your last drink. Quiet when you're on pace, silent until morning once you hit your goal • Add +250 / +500 ml right from the notification • Home screen widget: see your water level and add a glass with one tap • History: see what you drank and when, undo a wrong entry • Optional "Show over all apps": a faint water level on top of other apps that never blocks touches. Off by default, switch it off any time • No account, no ads, no internet permission. Your data stays on your phone

New: "Show on lock screen" option. The water moves with your phone on the lock screen as a live wallpaper.
