Behavioural science for follow-through

Mind the intention–behaviour gap.

Motivation is strongest when a goal is set—not when the work is due. A Bond turns intention into a measurable commitment, backed by a deposit and verified automatically.

Make intention binding.

Choose a measurable goal, put down a deposit, and connect your fitness data. FitBond verifies the work and settles the outcome under rules agreed upfront.

Choose the commitment

Set a measurable goal, a cadence, and a finish date. Join an existing Bond or create one for a group, friend, team, or cause.

Set your deposit

Choose an amount that matters to you. The app shows the payment, cancellation, fee, and outcome rules before you confirm.

Train. We verify.

FitBond reads progress from the source you connect. When the Bond settles, the result follows the rules everyone accepted at the start.

A transparent example

£40 → £60.40

Eight people deposit £40. Five finish and three forfeit. The forfeited £120 is reduced by the current 15% platform fee (£18), then £102 is shared equally by the five finishers. Each finisher receives £40.00 + £20.40 as cash-equivalent FitBond Coupons. Actual outcomes depend on the Bond type and its published rules.

Six ways to put follow-through on the line.

The mechanism changes by Bond type. The app shows exactly who receives a missed deposit and how a successful result settles.

Group

Fit Bond

Everyone commits to the same goal. Finishers recover their deposit and share the post-fee forfeited pool.

Cause

Charity

Missed deposits route to the chosen charity, less the platform fee defined when the Bond starts.

1 v 1

Head to Head

Two people take on the same clock. The winner receives the settled pool as cash-equivalent Coupons.

Together

Team

Teams compete on the same target. The winning team shares the settled pool according to the Bond rules.

47.4%

Volpp et al. · JAMA · 2008

A small randomized trial found stronger short-term results with deposit contracts.

In a 57-person, 16-week weight-loss trial, 47.4% of the deposit-contract group met the target versus 10.5% of the control group. The longer-term difference was not statistically significant, so this is evidence for the mechanism—not a guarantee for every goal.
