Health, home and travel decision
FitSaver
A small web replacement is realistic for one developer (scheduling, import, timers, storage), but reproducing the native iOS experience (App Store distribution, in-app purchases, share-extension, and any proprietary import/recognition polish) is not covered by this replacement.

Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All FitSaver alternatives, with the arithmetic →
What a replacement has to do
- Allow a user to paste a social video URL, extract video metadata and thumbnail, convert it into an exercise entry (name, sets, reps, rest), store it in a personal workout collection, and run a workout session with timers and completion tracking.
What it still won’t have
- Native iOS app and App Store distribution (share-extension, native UX/notifications)
- In‑app purchase billing handled by Apple
- Polished, iterative mobile UX and ongoing App Store updates
- Any proprietary workout-recognition or import-speed optimizations the app uses
What remains hard
- Product polish and ongoing maintenance

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a single-tenant web app (Node.js + Express backend, Postgres, React frontend) that accepts Instagram/TikTok/Facebook video URLs, fetches oEmbed/thumbnail/title, lets users convert a video into an exercise (name, sets, reps, rest), save workouts into collections, schedule workouts, and run a workout session with per-exercise timers and completion logging. Include email/password auth, a simple feature-flagged 'premium' subscription mode (no payment gateway integration required), input validation, error handling, and unit/integration tests. Out of scope: native iOS app, App Store in-app purchases, AI-based automated movement recognition, and large-scale multi-tenant billing.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
