Installation
- Download the APK for your device architecture (most E-Ink devices use arm64-v8a)
- On your device, go to Settings → Security and enable Unknown Sources (or allow installation from your file manager/browser)
- Open the downloaded APK file and tap Install
- Once installed, open EinkBro and start browsing
Tip: If you're unsure which architecture your device uses, download the arm64-v8a variant first — it works on most modern E-Ink devices including Boox, Kobo (with Play Store), and Kindle (with sideloading).
