A new kind of exercise app where walking lets you “send money to someone else”

The wish to “send it to someone you care about” becomes the engine that keeps you walking

You may want to walk for your health, but actually keeping it going is the hard part. Even when your company gives you points for hitting a step goal, the immediate appeal of watching TV usually wins.

ESPL doesn’t run on “walk and gain points” — it runs on the inverse: “if you don’t walk, you can’t give points to a friend.” That structure produces stronger motivation to start walking and to keep going.

What ESPL is good at

  • Example: a Challenger commits to walking 5,000 steps a day for 15 days, and a Sponsor backs them.
  • The Sponsor creates the challenge and provides the commitment deposit.
  • The Challenger walks every day and sends step data to the smart contract.
  • On success, the deposit goes to the pre-set “success-case Receiver” (e.g., the Challenger themselves).
  • On a miss, the deposit goes to the pre-set “failure-case Receiver” (e.g., family, a charity, fellow challengers, or the Sponsor themselves).
