Tern

Tern is not on this device yet. Download it below, open it once, then go back to the page you came from and tap Open in Tern again.

Install and update Android apps straight from where their developers publish them. Tern checks every file before Android sees it.

For Android 10 and later, on phones, tablets and TVs. About 5 MB. Each release lists the SHA-256 of its file.

What it does

• Follows the releases of apps on GitHub, GitLab, Codeberg and other Forgejo servers, SourceHut, SourceForge, Jenkins, F-Droid repositories and plain download links.
• Checks who signed each file, holds every update to the certificate of the first install, and compares the checksum the publisher gave. A file that fails is not installed.
• Says what it found in plain words, and keeps a log of every download, check and install.
• Works by remote on Android TV. A phone can send links and your app list to the TV, sealed with a code that never leaves the screen.
• Goes through Tor with Orbot when you ask it to, and never around it.
• Reads an export from Obtainium, so your list comes along.
• Needs no account, and has no analytics and no ads. It is free software under the GPL.
