This is the universal build of Squid: Take Notes, Markup PDFs 4.4.1-GP. It contains native libraries for every CPU architecture (arm64-v8a, armeabi-v7a, x86, x86_64), so it installs on any Android device. The trade-off is size — it's larger than per-architecture variants. Pick this one if you're unsure which CPU your phone has, or if you plan to share the APK with multiple devices.

Frequently Asked Questions about Squid: Take Notes, Markup PDFs APK
This is the universal variant — a single APK that contains native libraries for every CPU architecture. It installs on any Android device but is larger than per-architecture variants.
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 21 (API level 34) 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.
