Drink water reminder — tracker with weight-based goal (Android offline)

A GLASS THAT REMINDS YOU TO DRINK WATER

An animated glass fills with every sip: the goal is calculated from your weight (~30 ml/kg), quick-add buttons +250/+330/+500, undo, reminders and a day streak 🔥. Single HTML file, offline.

WHAT´S INSIDE:
• Animated glass with a wave — see the level without reading numbers
• Weight-based goal: enter kg — the goal computes itself (30 ml/kg, rounded to 50)
• Quick buttons +250/+330/+500 ml and −250 (floored at zero)
• One-button undo of the last addition
• Reminder: every N minutes the tab title becomes "Time to drink water!" (while the page is open and the goal isn´t met)
• Day streak 🔥: how many days in a row you drank
• 7-day chart: bars turn GREEN on goal days, a dashed line marks the goal
• Dark and light themes; data stays on your device, no network

WHY IT WORKS:
• A glass in front of you is a simple visual cue to drink more often
• The reminder doesn´t annoy: no full-screen notifications, just a gentle tab-title change
• Stats without pressure: green = goal met, blue = drank but less

FOR WHOM:
• Anyone forgetting water during computer work
• Fitness and weight loss: track your norm by weight
• Everyone who wants the habit without subscriptions or accounts
