This is the arm64-v8a build of KOReader (f-droid version) v2025.04 (arm-v7a) v2025.08 — the modern 64-bit ARM build that runs on virtually every Android phone released since 2017. It's smaller and faster than the universal variant because Android only loads the native code your CPU actually needs. If your phone is from the last 8 years, this is the right pick.

Frequently Asked Questions about KOReader (f-droid version) v2025.04 (arm-v7a) APK
This variant is built for 64-bit ARM (most Android phones made since 2017). If your device's CPU matches, this is the smallest, fastest version to install.
Yes — the APK's signature has been cryptographically verified against the publisher's signing key. The SHA-256 hash is shown in the File Information panel so you can independently confirm the file matches the original release.
Android 18 (API level 30) or newer. Older devices will refuse the install.
Install a free app like 'CPU-Z' or 'Droid Hardware Info' from the Play Store and look at the ABI / Instruction Set row. Most phones made after 2017 are arm64-v8a; if in doubt, download the universal variant.
All variants are functionally identical — same features, same version. They differ only in which CPU architectures the native code is compiled for, and (sometimes) which screen densities the included graphics target. Pick the one that matches your device for the smallest install size, or pick 'Universal' if you're unsure.
