Meter Burn
A self-coached training app for iPhone, iPad and Apple Watch — built, signed, reviewed and published to the App Store by the studio.
The problem it solves
Training apps tend to hand you a plan written for a stranger, or leave you doing arithmetic between sets. Meter Burn does neither: the athlete authors the programming, the app reads the log, and when an exercise has earned a step it proposes one — and then waits. Nothing changes unless the athlete agrees.
Why it is proof
It is a Swift application whose domain logic lives in a headless package tested without a simulator, behind a release pipeline that makes sixteen local assertions that the archive is genuinely distributable — and refuses to ship a data model that the production CloudKit schema has never heard of, the one failure no build-time check can see. Shipping to a reviewed store means the verification has to hold in public.
Handling health data without collecting it
The app reads heart rate, active energy and — only if the athlete switches it on — body composition from Apple Health, displays them, and stores none of it. Its App Privacy label reads “Data Not Collected”, which is a claim about architecture rather than policy: there is no server to send anything to.
The proof point
A regulated, reviewed distribution channel and health data handled correctly — in something the studio ships itself, where anyone can download it and check.
