Never forget to drink water. Track, remind, and hit your daily goal.
Read full description
Track your daily water intake, set a hydration goal that fits you, and build a consistent drinking habit with smart reminders.
Fill Up is a simple water tracker and hydration reminder that helps you log how much water you drink throughout the day. Reminders respond to your progress: they stay quiet after you reach your daily goal and tell you how much you are missing when you fall behind.
A daily water goal that fits you
Enter your height and weight to receive a suggested daily water goal, or choose your own target. See your current intake and progress at a glance.
Log water with one tap
• Small, standard and large cups, plus bottles
• Quick one-tap water logging
• Custom amounts for the glass or bottle you actually use
• Easy removal of accidental entries
Smart hydration reminders
Use water reminders that adapt to your day instead of following a rigid schedule:
• Notifications stop after you reach your daily goal
• See exactly how much water you are missing when you fall behind
• Choose your reminder window and frequency
• Set different reminder hours for weekdays and weekends
Hydration insights and statistics
Go beyond a basic water log and understand your drinking habit:
• Hourly water intake breakdown
• Averages for each day of the week
• Monthly goal completion rate
• Seven-day hydration chart
• Longest streak, best day, total water and active-day records
• Complete daily water history
Keep your hydration streak
Every day you reach your goal adds to your streak. If you miss a day, you can watch a short optional video to protect it.
Your data stays private
No account or sign-up is required. Your water log is stored on your own phone. Deleting the app also removes its locally stored data.
