Help check whether Bitcoin wallets are reproducible from sources

The **WalletScrutiny** app is primarily meant to collect APK files where they end up: on users' phones. At WalletScrutiny.com we test whether apps can be audited. For that, we have to check whether the app people actually run matches the source code the provider claims to have built it from. This app therefore monitors the list of wallets that WalletScrutiny.com considers **source available**. When you start the app, it searches your phone for these wallet apps and lists them. Every installation file gets fingerprinted and checked against our reproducibility tests. If we have tested those exact files, the results are shown. If the APK is unknown, the app uploads it and registers it publicly on Nostr so it can be verified. By installing this app you help us collect binaries from many devices and hold wallet providers accountable for their releases. Different countries and devices can receive different builds, so please contribute your binaries even if somebody else already did. For any wallet that holds your bitcoin, we recommend that you **disable auto-updates** and check this app or our website to see if the newer version was verified before updating.
