Kayyo

The APK is a regular Android package; download it from a reputable source, review the requested permissions, and keep your device’s security settings up to date.

Kayyo runs on Android 5.0 (Lollipop) and newer, as indicated in the compatibility table.

Core features like video lessons and real‑time feedback require internet access, while saved workout plans can be viewed offline.

No in‑app purchase information is verified for Kayyo; the app appears to be offered for free.

Installing the APK will replace any existing installation with the same package name; you can uninstall it later to revert to the Play Store version.

This usually means the APK is corrupted, not compatible with your Android version, or installations from unknown sources are disabled.

The latest update was released on 31 December 2024; future updates depend on the developer’s schedule.

The app may request access to storage, microphone and camera for video feedback; avoid entering sensitive personal information unless you trust the source.
