One Step Challenges

Read full description

One Step Challenges is a fitness competition app built for friends and family who want to compete fairly across different fitness levels. Like a handicap in golf, each user gets a personal multiplier based on their own fitness โ€” so a beginner and a seasoned athlete can go head-to-head on equal terms. Points are weighted by individual capability, not raw output. Effort wins, not genetics. Your handicap isn't a guess. The moment you connect Apple Health, the app measures it from your last 30 days of real data โ€” daily steps, active minutes, resting heart rate, and time in elevated heart-rate zones. Your first week confirms it, and it recalibrates every 30 days as your fitness changes. Start a 7-day challenge, send your crew the invite link, and everyone competes on their own handicap. When a challenge ends, the first person to hit "Run it back" starts the rematch โ€” and everyone else joins that same one, so your crew stays together week after week. No one to compete with yet? Race a bot. Three opponents, each with a different training style, each with a week you can beat. Pick the one that sounds like you and go โ€” Brian walks, Doug trains most days, Amanda never misses. Or race your Shadow โ€” the you from your own last four weeks. Same routines, same pace, built from your real history. Beat your typical week and you win; win, and your Shadow gets stronger, so the bar rises every time you do. It's the one opponent always exactly your speed. Daily activity is tracked automatically through Apple Health: workouts with heart-rate zone analysis, steps, exercise minutes, and active calories. Log on-plan nutrition with a single tap โ€” no calorie counting. Build daily streaks for consistency. Leaderboards show standings across everyone in a challenge, and you'll know when someone joins, cheers you on, or a challenge wraps up. Key features: - Handicap-fair scoring that levels the field across fitness levels - Handicap measured from your real Apple Health data the moment you connect, recalibrated every 30 days - Heart-rate zone analysis on every workout - Steps, active minutes, active calories, and resting HR tracking - One-tap nutrition logging โ€” no calorie counting - Daily streaks for consistency - Multi-user challenges with shared invite links and codes - Crew rematches that keep everyone in the same challenge - Leaderboard and today feed - Reactions to cheer on the people you're competing with, with notifications when they land - End-of-challenge recaps so every finish gets its moment - Built for honest measurement, not gamification tricks Works with Apple Watch, Garmin, Whoop, Oura, Fitbit, or any device that writes to Apple Health โ€” the more your device shares with Apple Health, the more the app can score. Steps and nutrition work without a wearable.
