The peer-to-peer fitness competition platform where you challenge friends across steps, distance, pace, sleep, and health scores, with real money on the line.
Harthos connects to your Apple Watch, Fitbit, Garmin, or any wearable to verify your fitness data in real time. Challenge a friend to a 10K step race, a weekly distance duel, or a 30-day sleep competition. Put money on it. Winner takes all.
No passive tracking. No empty badges. Just you, your rival, and something worth competing for.
From challenge to payout in the time it takes to lace up your shoes.
Pick a friend. Choose your metric: steps, distance, pace, sleep, or overall health score. Set the stakes. Send the challenge. They have 24 hours to accept or walk away.
Your wearable tracks everything in real time. No manual entry. No honor system. Anti-cheat algorithms filter out suspicious data. Every step is verified, every mile is earned.
When the challenge ends, the winner's payout hits their Harthos wallet automatically. Withdraw to your bank or roll it into the next challenge. The choice is yours.
When your money is on the line, you don't hit snooze. You don't skip the run. You don't settle for second place.
Live leaderboards sync with Apple HealthKit and Google Health Connect. Watch your competitor's progress in real time. No hiding, no surprises until the finish line.
Steps, distance, pace, sleep quality, and composite health scores. Challenge across one metric or combine them for a true all-around fitness showdown.
Head-to-head duels or group competitions with up to 20 players. Different stake structures for different formats. More players, higher stakes, bigger payouts.
Proprietary algorithms filter out treadmill desk noise, car-generated steps, and manual data entry. Only real physical activity counts. Every challenge is fair.
Powered by Stripe. Deposit to your Harthos wallet, compete, and withdraw winnings to your bank. Platform fees are transparent: 3% for 1v1, 5% for groups. A portion goes to charity.
Harthos competitions are classified as skill-based contests, not gambling. Legal opinion provided by gaming law specialists. Compliant with state regulations and App Store guidelines.
Peer-reviewed research from the University of Pennsylvania demonstrated that financial accountability dramatically increases fitness follow-through. Participants with money on the line were significantly more likely to hit their goals than those using tracking alone.
Harthos isn't built on a theory. It's built on a proven behavioral mechanism, packaged into a product people actually want to use.
"Financial incentives leveraging loss aversion produced sustained physical activity increases compared to control groups receiving only feedback."
