Drink more water, without another app nagging you. Aqua is a water reminder and drink tracker that logs a glass in one tap and gets out of your way. Most water tracker apps show an ad every time you log a glass. Aqua never does. Logging is instant, the bottle fills smoothly, and your reminders stop the second you hit your daily water goal. ONE TAP TO LOG - Tap a container size and you are done — no dialogs, no forms - The water level rises immediately, so logging a drink feels like progress - Undo any accidental tap straight from the snackbar - Keep up to eight custom container sizes EIGHT DRINK TYPES, HONEST MATH - Water, coffee, tea, juice, soda, milk, smoothie and a custom type - Each drink adds its real hydration value to your daily total: coffee 80%, tea 90%, juice 85%, soda 70% - A water tracker that counts coffee as coffee, not as water YOUR DAILY WATER GOAL - Calculated from your weight, activity level and climate, or set your own between 500 ml and 5 litres - Choose your vessel: bottle, glass, sports bottle, mason jar or a minimal ring - ml, litres, fl oz or cups — your units, everywhere in the app SMART REMINDERS THAT KNOW WHEN TO STOP - Choose your interval and your waking hours - Reminders stop the moment you reach your daily goal - Bedtime hours are respected automatically, so nothing wakes you SEE YOUR HABIT BUILD - Today's timeline, weekly chart and a monthly heatmap of every day you hit your goal - Streaks, best day, daily average and 15 achievements to unlock - Export to PDF or CSV, and back up everything to a file you own SEVEN THEMES, INCLUDING TRUE BLACK - Ocean, Dark Ocean, Night (AMOLED), Fresh, Coral, Minimal and Sunset - Home screen widgets in two sizes PRIVACY AND RESPECT - 100% offline.
