Frequently Asked Questions about Onoff Numbers APK

This variant is built for devices that report `arm64-v8a, armeabi-v7a, x86, x86_64` as their primary ABI. 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 26 (API level 35) 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.
