[A] — What it does
A field guide that doesn't need a signal.
- ZonesSeven habitats — farm, forest, wetland and more. Farm is free; the rest are small one-off packs.
- Field guideEvery species card carries its scientific name, taxonomy and conservation status — tap to learn, not just to listen.
- GamesGuess That Sound and a Daily Quiz that's the same for everyone, every day.
- Offline-firstEverything lives on your phone. Turn the plane mode on — nothing changes.
[B] — Provenance
Every sound is traceable.
- SourceEach of the 52 shipped recordings ships with a machine-readable provenance sidecar: source URL, licence, creator.
- LicencesAll 52 recordings are licence-cleared and checked at build time. No no-licence files ship, ever.
- In-appAn attributions screen inside the app lists every source — because it should.

- DataThe app collects no user data. No analytics, no crash reporting, no ad SDKs.
