What you get in the app

A daily step goal sized to you, a one-tap water log, a team of two to four with its own chat, and a live leaderboard with solo, team and global ranks. Winners go up Friday morning, and a new round starts Tuesday.

Works across iPhone & Android

Steps come from Apple Health on iPhone and Health Connect on Android, so friends with different phones can share a team. Many watches count too, once they share steps with those apps.

Why rounds instead of a never-ending streak

Endless streaks feel great until you miss a day. Three-day rounds give you a finish line every week and a clean start every Tuesday. Since Fitbit retired its Challenges in 2023, a lot of friend groups have been looking for exactly that kind of regular competition.

Walk it with a team this week

Join a team of 2–4, walk & drink your water Tuesday to Thursday, and see the winners Friday.

The 3-Day Walk & Water Challenge

How a round works

  1. 1. Join a team

    Two to four of you on one team: a friend’s, your own, or one you join in the app. Your team gets a name, a crest & a spot on the live leaderboard.

  2. 2. Walk + water, 3 days

    Tuesday, Wednesday & Thursday. A step goal & a water goal sized to where you are today. The board updates as you walk & closes Thursday at midnight, Arizona time.

  3. 3. Friday winners

    Friday morning the results go up. The winning team’s card glows gold, badges land beside names on the board, and a new round starts Tuesday.

Bigger isn’t better. Teams rank on their AVERAGE.

A team’s score is its average per woman, not its total. So two friends can beat a team of four, and every walker’s day counts the same. When one of you goes quiet, the others notice & send a nudge in team chat.
