The problem

Wanting to get fit is easy. Showing up is the hard part.

Most fitness goals don't fail for lack of a plan. They fail because skipping today costs nothing and nobody checks the work.

  1. $17paid per gym visit

    We pay, then don't show up

    Members on flat monthly gym plans averaged 4.3 visits a month: over $17 a visit, when a $10 pass was on offer. Good intentions are cheap.

    DellaVigna & Malmendier, “Paying Not to Go to the Gym”, American Economic Review, 2006

    Fitr

    Your own SKR goes on today's goal. Show up and it comes back. Skip it and it's gone.

  2. ½a half-rep logs as a full one

    Nobody checks the reps

    Workout logs count whatever you tell them. Half-reps, skipped sets and yesterday's video all count the same, so a streak proves very little.

    Fitr

    On-device AI holds every rep to a joint-angle standard, and random live challenges catch pre-recorded clips.

  3. 2×losses weigh about twice as much as gains

    Skipping costs nothing

    Missing one workout costs you nothing today, so “tomorrow” keeps winning. Commitment contracts with real money at stake have helped people keep promises they kept breaking.

    Tversky & Kahneman, 1992 · Giné, Karlan & Zinman, “Put Your Money Where Your Butt Is”, 2010

    Fitr

    Every day settles onchain: finishers get their stake back plus a share of what the no-shows forfeited.

How it works

Stake it. Sweat it. Settle it.

Motivation fades. A promise with something on it does not. Fitr turns your daily workout into a commitment you can't quietly skip.

  1. Step 1: Commit

    Pick an exercise, set your daily goal and choose how much SKR to stake. One transaction, signed on your phone.

    Goal minimums are enforced onchain

  2. Step 2: Work out

    Prop up your phone and go. On-device pose AI checks your form and counts every rep that meets the standard.

    Runs entirely on your phone

  3. Step 3: Get verified

    Fitr's verification server replays your pose data and checks random live challenges, then marks the day complete onchain.

    Live challenges, rep by rep

  4. Step 4: Settle

    Hit your goal and claim your stake back plus a share of what no-shows forfeited. Miss it and your stake goes to the people who showed up.

    Paid out by the onchain vault

Why it's different

A commitment device, not a money game.

Fitr isn't move-to-earn. You only stake your own SKR on your own goal, and the rules that decide who gets paid are open for anyone to read.

Cheat-resistant by design

Backed by live challenges and onchain rules, built to catch half-reps and pre-recorded clips before a day is marked complete.

  • Strict rep standards. Joint angles decide what counts, not motion.
  • Random live challenges. “Raise your right hand”, mid-set, re-checked by the server.
  • One Seeker, one stake. No farming a pool with a drawer of wallets.

Your video stays yours

Pose tracking runs on your phone. Video is never uploaded or stored; verification only sees skeleton points.

Transparent on Solana

Every stake, verification and payout is a public transaction. Stakes sit in the vault program. Fitr can't touch them.

Live pool stats

One honest fee

Fitr takes 5% of forfeited stakes, and nothing else. Show up and you pay no fee at all.

Example day: 10 people stake 100 SKR. 7 show up.
