Smart reminders

Flow spreads your goal across your waking hours and reminds you only when you fall behind pace. When you're on track, it stays quiet.

  • Stop once you reach your goal
  • Never in the hour before bed
  • Log a drink or snooze right from the notification

A goal that fits your body

Your daily goal is worked out from your weight, how active you are and your usual climate, with every line shown so you know where the number comes from.

  • Or set your own goal any time
  • Hot day adds a little extra, just for today
  • Workouts from Health Connect or Apple Health raise the goal on active days

Log any drink in a tap

Tap + for your usual cup, or pick from 12 drinks: water, tea, coffee, milk, juice and more. Coffee and tea count too, at a slightly lower rate.

  • Your own cups and bottles as quick buttons
  • Swipe to edit or delete, and fix earlier days

See your progress

A history calendar shows every day at a glance. Weekly and monthly charts, the time of day you drink and your drink mix help you understand your habits.

  • Fill in or fix any past day
  • Share a daily or monthly recap card

Streaks, challenges and badges

Every day you reach your goal grows your streak. Join small challenges and earn badges along the way: small wins that keep you going.

  • A streak freeze each month keeps your streak safe
  • No challenge ever asks you to drink more than your goal

Log from your home screen

See today's progress at a glance and log a cup straight from the widget, without opening Flow. The water level updates right away.

  • A progress widget and a quick-log widget
  • Follows your phone's light or dark mode
  • On iPhone, lock screen widgets and a Live Activity too
