02 Which Android version does 21 Days Challenge need?
The current release requires Android 7.0. If your device is older, one of the 30 earlier versions listed above may still install.
03 How do I install the APK?
Download the file from the version page, open it on your Android device and allow installs from this source when prompted. XAPK bundles need the APKPure app or a split-APK installer (see the install guide in the footer). Always prefer the latest version unless you specifically need an older build.
04 Is the download safe?
Files are served by an established third-party mirror and are the same builds distributed to Play Store users; APK Apex never repackages or modifies them. Check the developer name (Kati & Lima) and package name (com.limatech.dayschallenge.dayschallenge) match what you expect.
