Shares Whoop's exact hardware problem: the app half (tracking, leaderboards, a class library) is buildable, but there's no code substitute for the connected exercise bike and its production studio.
VIBE SCORE 95/100
A moderate score above just means the individual parts are buildable — it isn't a build/buy recommendation on its own. Here's the actual reason this one's still JUST PAY:
The parts this build actually needs, each rated on its own — the average is the Vibe Score above.

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $86–$172 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
Peloton costs $44/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 4 months.

Peloton costs $44/mo (about $528/yr) as of 2026-08. That's what a working rebuild would save you.
The connected hardware (bike, treadmill, resistance sensors synced live to a screen) is manufacturing engineering, categorically outside a software build A continuous studio production of new, professionally-instructed classes is content production at real scale, not a database of videos Live class leaderboards synced to thousands of simultaneous riders need real-time infrastructure of their own
