Profile

FitVow is my personal commitment-device experiment: I lock funds in a smart contract for 12 weeks, define weekly fitness goals, and if I miss a week a penalty becomes enforceable.Enforcement is permissionless: anyone can call the contract and a portion of the penalty is paid to the caller; the rest goes to a charity (Giveth).Weekly activity data comes from my smartwatch (via Samsung Health / Health Connect), synced by an Android app that publishes the weekly activity on-chain.The site is mostly a viewer for on-chain state.
