MoveCommit — A Commitment Contract for Daily Movement
A behavioural-health prototype built around commitment contracts: you pledge against a daily step goal, and loss aversion does the motivating. An interactive concept demo exploring whether 'put something on the line' beats points and badges.
The situation
Most fitness apps reward you for moving, and rewards are weak motivation — a badge you forget about by lunch. Behavioural science is blunt about it: people work harder to avoid a loss than to chase a gain. The open question is whether a commitment-contract model — where you stake something on hitting your own goal — actually changes behaviour, and whether it can be designed responsibly rather than as a gambling product in disguise.
What I built
MoveCommit is an interactive prototype that makes the idea tangible: a member 'My Day' view, a crew view for social accountability, and a governance view — all running on a seeded, simulated dataset so the mechanics can be felt without any real money moving. The build deliberately wears its honesty on its sleeve: every screen is badged as a demo on simulated data, and the governance view frames the regulatory question openly rather than pretending it's settled. It's a prototype for thinking clearly about a sensitive model before a single cent is ever staked — exactly where a behavioural-finance idea should start.
Highlights
- Explores loss aversion over points-and-badges for habit change
- Member, crew and governance views on a seeded, simulated dataset
- Honesty-first: demo badges everywhere, no real money, no traction claims
- Regulatory posture framed openly as an open question, not a settled one
- A concept demo for pressure-testing the model before any real-money build

Built a Phase-1 interactive concept demo on simulated data, with honesty guardrails and an open compliance posture.
