Glassful: Water Reminder

Glassful is a water reminder and drink log with no ads anywhere. It reminds you on a steady schedule, lets you log a glass in one tap from the notification or a widget, and lets you fix any entry. No account needed, and it works offline.

• No ads: no banners, no videos, no pop-ups after you log a drink
• Reminders on a fixed schedule between your wake time and bedtime, every 30 to 120 minutes. Logging a drink never pushes the schedule around
• Ahead of your goal? That reminder is skipped. Once the goal is reached, reminders stop for the day, and nothing rings between bedtime and wake time
• Reminder diagnostics show notification permission, channel, battery optimization and the next scheduled reminder, with a shortcut to each system setting
• Log from the notification or the home-screen widget without opening the app, or tap a glass preset in the app
• Every entry can be changed: amount, drink and time, including drinks you forgot earlier today or yesterday. Undo is one tap
• Your goal starts at a moderate 2,000 ml (64 fl oz in the US). An optional calculator suggests a range, and you decide. General guidance, not medical advice
• Reminders, unlimited logging, 3 glass presets, 1 widget, the weekly chart and streaks, dark mode and JSON backup are all included without Pro
• Pro adds 12 drink types with editable hydration factors, monthly and yearly charts with hourly analysis, CSV export, up to 8 presets, widget themes and alternate app icons
• Pro is a one-time purchase, not a subscription, or pick the monthly plan with a 7-day trial
• Millilitres or fluid ounces, and a day that can start after midnight for late nights. Your drink log stays on this device, with Android backup and file export
