Kofi is learning jazz piano. Each session he uploads a 30 second clip hash and peers spot check random ones; after two years his Practice Log shows 1,840 verified hours, which gets him into a conservatory that cares about grit.
Session logging with media hash, peer spot check queue, hour counter attestations, public profile.
Reshape it entirely: new features, your flows, your brand end to end, integrations you need. We scope it with you.
Practice logging onchain exists in student projects; peer spot checks on cumulative hours are uncommon.
Proof of Practice (Solana devnet) mints learning milestones from practice logs, and BSV BRC-168 commits weekly hours with optional countersigning; no peer-verified hour ledger found live.
Checked with web searches in October 2026. A search is not proof that nothing similar exists, and the market moves fast, so we recheck before every build.
Shipped Base consumer app; retroactive.
If deployed on Solana; existing projects allowed.
The complete Practice Log app: learners commit every practice session with randomly timed clip hashes, peers spot check a few, and verified hours become a record they own and can send to a school, with a paywall, owner console and checker router built in.
Every buyer gets the same finished app. Basic branding and copy changes come through a quick form.
Your admin side: revenue, paywall editor, users, rules and the agent log.
Referral and growth mechanics, switched on when you are ready to grow.
Logging and checking are free forever. Learners who want to show their hours pay for Portfolio, and teachers and academies pay for Studio circles and term reports.
Gas on Base is a fraction of a cent per session and sponsored by the owner.
Prices are yours to set. Illustrative, not a promise of income.

Custom work from $800: new skills and media types, school or federation integrations, or a branded academy deployment. Scoped on a call.
The recipe (how it is built, the data, costs, risks, build order, the pitch and the demo script) is unlocked when your app is paid in full.
Self taught musicians, athletes and craftspeople put in thousands of hours that nobody sees. Schools, coaches and scholarship panels ask for evidence of sustained practice, and the best most people can show is a private notebook. A record that is checked by peers, and owned by the learner, is hard to find.
Parts of this exist. Proof of Practice, a Solana devnet project, mints learning milestones from practice logs, and BSV BRC-168 commits weekly practice hours with optional countersigning. Research verdict: rare, medium novelty. What this app adds is random-minute clip fingerprints plus a peer spot check queue on cumulative hours, with rejected sessions kept visible. It is a modest combination of known pieces, not a new primitive, and we did not find a live peer verified hour ledger.

Let anyone turn their quiet daily practice into a record they own and that others can trust.
The counter A verified hours number that only goes up when real practice is heard. People open the app just to watch it move.
Check two, get checked fast Checking peers earns credits that move your own clips up the queue. The circle keeps itself honest.
Rejected stays visible A failed session is struck through, not hidden. That honesty is what makes the total believable to a school.

Cost per use: unlocked when your app is paid in full.
Every shared profile shows who checked the hours, and checkers need their own circle, so each learner invites a few peers. Teachers bring whole classes through the Studio tier, and every verified profile sent to a school is a quiet advert.

Practice Log turns your hours of deliberate practice into history you can prove. Owning it means the learners, teachers, and schools you bring in are your community, the fees are yours, and the record of every verified hour is anchored to your app. On someone else's platform, your learners' grit lives in their database.
You do not need to. Practice Log ships ready to deploy, and every path here is written for non coders. When you want to change something deeper, you can hire help or ask DEPLOYR support.
Yes. It is deployed from your wallet, the contract address is public, and the brand, users, and revenue are yours. DEPLOYR does not hold your keys or take a cut of your app's revenue.
Peer spot checks on random clips make faking harder, not impossible. Be honest that it is verified practice, not a guarantee.
Start with teachers and coaches who already ask students to log practice. They see the value first.
Only hashes go onchain. Clips stay with the learner unless they choose to share them for a spot check.
You charge learners a small monthly fee and teachers or schools a group fee for verified practice dashboards. $1M a year is a target, not a promise.
Illustrative stages, not a forecast. Results depend on you and the market; nothing here is guaranteed.
