IPA and APK inspector
Before you send a build to testers or a store: which version is it, how is it signed, who can install it and what it asks for. No Xcode, no Android SDK, and the file never leaves your computer.
iPhone builds
Info.plist (version, build, minimum iOS, Xcode and SDK) and the embedded provisioning profile: development, ad hoc, App Store or enterprise, the team, the expiry date, how many devices can install it, push and other entitlements.
Android builds
The compiled AndroidManifest.xml (package, versionCode, min and target SDK, permissions, debuggable), the native ABIs and the signing schemes: v1 files and the v2/v3 APK Signing Block. Bundles show modules, ABIs and size.
Checks
Expired or soon expiring profiles, Simulator or unsigned builds, debuggable APKs, a target SDK under Google Play's current rule (36), v1-only signing, no 64-bit code and permissions that need a Play declaration.
