The Android edition needs a tablet with an ARM processor (i.e. not the Intel processor),
and a minimum screen size of 7'' is recommended.
To start the download, you tap in the (Chrome) browser of the device on the link:
Download for Android 5 - 9 Download for Android 10 - 13
You best wait until the download (153 MB) is finished, then tap on it to install the app.
After the installation you see Defence in the Apps, either in alphabetical
order
or as most recent app (rather at the end).
