Install Checklist
- Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
- File size is a light 1.59 MB, so it installs quickly even on modest connections.
- This build is signed by "woheller69" — always verify the developer name matches what's listed on the app's official store page before installing an update.
- 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.
- 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.
