Installing Olympus Air Central app from outside the US or Japan

Olympus decided not to make the Air Central app for Android available outside of the US or Japan.

Good that websites exist that rip the apks from the Play Store and make them available for download.

Like this one:

Download the .apk on your device, activate 'Unknown sources' in your Preferences/Security tab, run the .apk file and you are golden. You will need to install updates the same way though...
