Test Protocol Vault on Android.
This is a pre-release build for invited testers. It installs directly on Android without Google Play.
How to install the test build.
Because this test build is not being distributed through Google Play yet, Android will ask you to approve installation from the app you used to download it.
Tap the download button above and save the Protocol Vault APK to your phone.
Open the downloaded APK. If Android blocks it, choose Settings and allow installs from that source, then return to the installer.
Tap Install, open Protocol Vault, and use it normally. Please report anything that behaves unexpectedly.
