Fitr turns "I'll work out tomorrow" into a promise with something on it. This page is about where Fitr goes after the hackathon: who it is for, how it makes money, why it belongs on Solana Mobile, and the concrete next steps. Everything marked Live runs on Solana mainnet today; everything else is a plan, stated as one.
- The problem is universal. People pay for fitness and do not show up: gym members on flat monthly plans averaged 4.3 visits a month, paying over $17 a visit when a $10 pass was on offer (DellaVigna & Malmendier, American Economic Review, 2006). Motivation fades; commitments hold.
- Money on the line already works. Commitment contracts help people keep promises they keep breaking (Giné, Karlan & Zinman, 2010), and consumer businesses have been built on the idea (stickK, Beeminder, DietBet / WayBetter). What they lack is proof: they trust self-reported workouts or a photo of a scale.
- Fitr adds the proof. On-device AI counts every rep against a joint-angle standard, random live challenges stop pre-recorded clips, and the result settles onchain by rules nobody can bend. Video never leaves the phone, so it works on modest data plans.
Fitr is built for the Seeker, not ported to it:
| Seeker / Solana Mobile piece | How Fitr uses it | Why it matters to Solana Mobile |
|---|---|---|
| Seeker Genesis Token | One Seeker, one stake: the vault checks a real SGT and a per-device lock | A reason to own a Seeker: commitments are Seeker-only |
| Seed Vault + Mobile Wallet Adapter | Every stake and claim is signed in the phone's secure hardware | Shows Seed Vault in a daily, non-trading habit |
| SKR | Stakes, forfeits, the sponsor reserve and the 5% fee are all in SKR | Real, recurring utility for SKR (locked daily, recycled to finishers) |
| dApp Store / native Android | A real Android app with camera, voice coach, reminders, widget, shortcuts and App Links | A daily-active app on the Seeker home screen |
| Blinks / Solana Actions | "Commit with me" and "Sponsor a day" work from any wallet or social post | Brings people from X and chats straight into Seeker flows |
The flywheel. Each day people lock SKR on their own goal → the ones who show up take back their stake plus what no-shows forfeited → sponsors (brands, gyms, the community) add SKR to the reserve as a bonus for showing up → more people commit, and more of them want a Seeker to do it. Fitr is a habit people open every day, which is exactly what a phone ecosystem needs.
- Seeker owners (now). Crypto-native users who want accountability with real stakes. Live.
- Gyms and their members (next). Gyms lose members when motivation fades. Fitr gives them challenges, crew leaderboards, AI-verified home workouts on non-gym days, and a view of who is slipping. The founders have direct relationships with gym owners in Nigeria; a pilot is the first step after the hackathon.
- Everyday users (later). People who have never held crypto: phone or email sign-in, Play Store listing, local payments, prizes funded by sponsors before any user money is at stake.
| Revenue stream | How | Notes |
|---|---|---|
| Gym partnerships (B2B) | Gyms pay Fitr monthly to run challenges for their members: leaderboards (crews), AI-verified home workouts on non-gym days, and a dashboard of who is slipping | First market: gyms in Nigeria. The gym's real problem is members quitting; Fitr shows who is showing up. |
| Sponsored challenges | A brand (sportswear, drinks, a telco) or the gym funds the prize for finishers | Uses the live sponsor feature. No user money involved: the lowest regulatory risk. |
| Subscription ("Fitr Pro") | Free: rep counting, streaks and staking. Paid: programs, advanced stats, more crews and advanced workouts (pistol squats, handstand push-ups, …) | Paid monthly in SKR, cheaper when a whole crew joins: steady, non-speculative demand for SKR. Previewed in the app as "coming soon". Local-currency pricing for everyday users later. |
| Corporate wellness | Employers (banks, telcos) sponsor staff challenges | Larger contracts, repeatable |
| Money commitments | The 5% fee on forfeited stakes only (nobody who shows up pays it) | Live on mainnet in SKR. Fiat versions only after legal review (see Risks). |
| Phase | When | What | How we will measure it |
|---|---|---|---|
| 0. Live today | October 2026 | Mainnet vault (Squads 2-of-3, verifiable build), staking, verification with live challenges, crews, sponsored days, Blinks, 9 languages, Android app | Onchain: stakes, verified days, sponsor reserve (public at fitr.day/pool) |
| 1. dApp Store + Seeker growth | Weeks 1-4 after the hackathon | Solana dApp Store listing, crew challenges with the Seeker community, sponsored "showing up" weeks in SKR | Weekly active stakers, verification pass rate, day-7 and day-30 retention |
| 2. Gym pilot (Nigeria) | Weeks 4-12 | 1-2 gyms run a 30-day challenge with a gym-sponsored prize; members use Fitr at home and at the gym | Attendance and retention vs. members not using Fitr; a published case study |
| 3. Everyday users | Months 3-6 | Phone / email sign-in (wallet optional), Play Store listing, subscription with local payments, stablecoin stakes alongside SKR, performance on low-end Android | Paying subscribers, gym contracts, cost per active user |
| 4. Scale and decentralize | Months 6-12 | Corporate wellness, more gyms and cities, iOS, more attestors so verification no longer depends on one server | Revenue per gym, number of independent attestors |
In a few weeks of building we shipped, on Solana mainnet, a vault holding real money with no single point of control (Squads 2-of-3 owns the program and the pool; the deployer key was emptied), a reproducible build anyone can verify, 79 program tests including 256 randomized scenarios, two internal security review rounds, an AI rep counter for 16 exercises, a verification server with live challenges, a native Android app, and the app in nine languages. The full list is in the README.
- Distribution: a dApp Store feature and the Seeker community for the first crew challenges.
- SKR sponsorship: a sponsored "showing up" season funded in SKR, which directly grows SKR's utility and Fitr's daily actives.
- Grant / backing: to run the gym pilots, ship phone sign-in and the Play Store version, and add independent attestors.
- Regulation of money pools. Paying one user's forfeit to other users can be classed as betting in some countries (in Nigeria, gaming regulators at national and state level). Mitigation: start with sponsor-funded prizes (no user money), offer forfeits-to-charity, and take legal advice in each market before any fiat stakes.
- Trust in verification. Today Fitr's server is the attestor. Onchain limits already contain it (per-day rule snapshots, refund-only revokes, a review window in which the multisig can void a day); the plan is more, independent attestors.
- Cheating. Cheat-resistant, not cheat-proof: live challenges make faking expensive, not impossible. The money at stake per person is bounded by the pool's limits.
- Device reach. Staking is Seeker-only by design today; everyday users first get the free AI coach and sponsor-funded challenges, which need no Seeker.
