Install Checklist

  1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
  2. File size is a light 2.92 MB, so it installs quickly even on modest connections.
  3. This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
  4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
  5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.
