Purchasing and licensing: bought from Amazon

You have said that you have bought the Universalis app from the Amazon Appstore. Apps sold by Amazon work only on Amazon devices such as the Kindle Fire.

If you want Universalis on Android devices

The best and most flexible way

A Universalis registration code gives you access on all the devices and systems we support: mobile devices, laptops and desktops.

Since you have already bought the Universalis app from Amazon, you have already paid half the price of a Universalis registration code. If you now buy a registration code from us by paying the second half of the price, you will have full flexibility for the future because the code will work on Android devices, Apple devices, Mac, Windows, and e-books.

Buy a Universalis registration code at half price – £9.99 (about $12.60 or €11.50) – using the Universalis app on your Amazon device. The instructions are here.
On your Android device, get Catholic Calendar (it's free) and put your registration code into it. Instructions are here.

Note that to do this, you do still have to have a device with the Universalis app that you bought from Amazon.

The quickest way

Just buy the Universalis app from Google Play. The instructions are here.

You don’t lose any money doing it like this. But the app you get will work on Android devices only (and not, for instance, on Apple devices or Mac or Windows), so you do lose a little flexibility for the future.
