How to install

  1. Download trakta.apk to your phone.
  2. Open the file. The first time, Android asks whether your browser may install apps – allow it. You only need to do this once.
  3. Tap Install, then open Trakta.

Android may warn you that the app does not come from Google Play. That is expected for apps downloaded directly.

Updates

Trakta has no internet access, so it cannot check for a new version itself. Pick what suits you:

Come back here

Check this page now and then. You can see which version you have in Trakta under Settings.

Watch on GitHub

With a GitHub account you can watch the project’s releases and get notified when a new one is out.

Obtainium

Obtainium is an open source app that installs and updates apps straight from GitHub. Add this address to it:

A new version installs over the old one, and everything you have entered stays.

Using the test version from Google Play?

Then you can keep using it – Google Play takes care of updates. If you would rather switch to the version from here, move your data with a backup. The two versions are signed with different keys, which is why Android will not install one over the other.

  1. Create a backup in Trakta under Settings → Backup. Save the file outside the app, for example in Downloads or Google Drive.
  2. Uninstall Trakta. Everything in the app is deleted, so make sure the backup is saved first.
  3. Download and install Trakta from here.
  4. Open Trakta, choose “Restore a backup” and enter the password.

iPhone

Trakta for iPhone is coming later, but there is no date yet. Follow the project on GitHub if you want to know when.

Verify the download

For those who want to know exactly what they are installing.

The app is signed with a certificate that has this SHA-256 fingerprint:

20:EE:F0:03:4B:0B:29:D6:4E:3A:25:23:B8:9C:7D:27:D6:AD:91:DD:B8:97:B0:AD:EE:DB:A2:11:AA:2F:66:3E

Compare it with what Android’s apksigner tool shows:

apksigner verify --print-certs trakta.apk

Every version on GitHub includes SHA256SUMS.txt with the SHA-256 checksums of its files.

Every APK is built from the source code in GitHub Actions and gets an attestation of where and how it was built (build provenance). With the GitHub CLI you can verify it like this:

gh attestation verify trakta.apk --repo Dan-Irl/Trakta

Build it yourself

All the source code is on GitHub, along with instructions for building the app.
