Stackly Glass

Stackly Glass is a manual water tracker where users add the selected glass preset with one tap, while the main screen shows a growing vertical stack of glasses for the day. Daily Glass Stack The main idea of the app is a stacked-glasses progress visual. The stack shows the number of glasses today, selected glass volume, daily total, daily goal, remaining amount, progress percentage, and Goal reached state. One-Tap Add Glass The main action on the home screen is Add Glass. When tapped, the app creates a water entry, adds a new glass to the stack, and updates daily total, progress, and remaining amount. Glass Presets The app includes default presets: Small Glass, Regular Glass, Large Glass, and Bottle. Users can select the active preset, edit preset name and amount, and reset presets to defaults. Custom Amount Users can add a custom amount, such as Add 180 ml. Custom entries appear in the stack as a separate glass with a small visual difference. Undo Latest Glass Undo removes the latest entry for the current day, removes the top glass from the stack, and recalculates daily total, remaining amount, progress percentage, and Goal reached state. History & Statistics History shows previous days as a shelf of glass stacks with date, daily total, goal state, number of glasses, and small stack preview. Statistics include last 7 days total, daily average, best day, goal days count, and total glasses this week. Stackly Glass combines one-tap water entry, glass presets, a vertical glass stack, custom amounts, undo, history, and simple statistics in one stacked-glasses water tracker.
