Step-a-thon turns everyday walking into a fun, friendly challenge for your whole group. Record a walk and your steps are counted right on your phone, then added to your total on a live leaderboard. Climb the rankings, cheer on your teammates, and collect badges as you hit new milestones. Built for organized step-a-thon events — schools, workplaces, colleges, and community groups — Step-a-thon makes it easy to run a healthy, high-energy activity where everyone can take part. WHAT YOU CAN DO • Record your walks and count steps automatically using your phone's motion sensor • Watch a live leaderboard update as you and your teammates rack up steps • Join a team and compete together toward a shared goal • Earn badges as you reach new milestones • Track your personal progress over the course of the event FOR EVENT ORGANIZERS Administrators can set up events, manage participants and teams, and follow standings in real time — everything you need to run a smooth step challenge. PRIVACY FIRST Step-a-thon collects very little. Your phone's motion sensor is used only while you're recording a walk, and only the resulting step count is saved — never the raw sensor data. No location tracking, no ads, and no third-party analytics. Read our privacy policy at https://steps.eskoops.com/privacy. Lace up, start walking, and see how far your team can go.
