Just Breathe: Relax Daily
A competent developer can build a usable offline breathing-timer app (the core experience) in a few weeks, but reproducing the vendor's app-store polish, subscription handling, and any proprietary premium content would require extra work and ongoing ops.

Not priced
No pricing page we fetched carried a figure, so there is nothing to compare against. The build side is still real.

No published price to break even against.
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
- Start a guided breathing session (animate inhale/hold/exhale, play theme sound), record session metrics locally, show session history and progress.
What it still won’t have
- Polish, branding, and app-store marketing reach of the existing product
- Any proprietary premium content or features behind the app's subscription (product pages mention premium features and a 7-day trial)
- Ongoing app-store review, ratings, and cross-device QA handled by the vendor
- If present, any analytics/telemetry or remote feature flags the vendor runs
- Potentially advanced integrations (push notifications, cloud sync) unless added
What remains hard
- Product polish and ongoing maintenance
First-year cost
No published price
Just Breathe: Relax Daily does not publish a price we could read, so there is nothing to compare against. What building costs is below.

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal cross-platform breathing app in React Native (Expo) that runs offline: implement animated inhale/hold/exhale coach, play bundled theme sounds, allow selecting and saving preset and custom breathing patterns, record session duration and pattern used to a local SQLite/AsyncStorage-backed history view, include a simple settings screen, and implement in-app-purchase hooks (no backend billing server). Out of scope: cloud sync, analytics backend, advanced personalization. Include error handling, unit and integration tests, and CI build scripts for App Store and Play Store submission.
How we checked
How the score was reached
- Partly verdict base52
- 3 cited sources+3
- Evidence score55
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.
