# Mobile build storage and sharing

AppBarn keeps IPA, APK and AAB artifacts with their build identity, checksum, environment and recorded source provenance. It is a build archive, not a replacement for CI, TestFlight or app stores.

Choose the problem you need to solve:

- [Keep IPA and APK builds after CI artifacts expire](/use-cases/keep-mobile-builds).
- [Find an older iOS or Android build](/use-cases/find-previous-build).
- [Share an IPA or APK with a tester without an account](/use-cases/share-ios-android-build).
- [Add durable build storage to your CI pipeline](/use-cases/ci-artifact-archive).

**When not to use it:** If your current CI artifact retention and tester distribution already meet your needs, adding another build service may not help. [Compare AppBarn with existing tools](/ai/compare).
