Paced breathing exercises zone
A competent mobile developer can reproduce the core guided‑breathing app and local journaling in about a week; there are no durable moats on the App Store page that prevent a rebuild.

No open-source build does this yet
Nothing published replaces this one, so a replacement starts from an empty file. Here is what it would have to cover.
What a replacement has to do
- Open app → select breathing technique → follow timed visual/audio cues → session recorded to local journal.
What it still won’t have
- App Store subscription management and revenue flow (if you don’t publish through App Store)
- Curated meditation catalogue unless you license or create your own content
- App Store distribution, ratings, and automatic device updates
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‑target iOS app (SwiftUI + Combine) that implements a guided paced‑breathing trainer. Core features in scope: home screen with technique list, selectable breathing patterns, active session UI with animated visual guide, haptic/timer cues, AVFoundation audio playback for optional meditation tracks, local persistence of session records using Core Data, settings screen, and CSV export of session journal. Out of scope: App Store submission and paid subscription billing (implement a local unlock toggle instead). Include proper error handling, unit tests for timer and persistence logic, and basic UI tests for the session flow.

How the score was reached
- Build verdict base78
- Price verified on pricing page+3
- Evidence score81
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.
