We’ve always been in favour of selling Universalis all in one go, whether as a registration code or as an app. It saves administration, for one thing. But people have asked us, now and then, about subscribing instead. A single lump of £10 ($12-ish) for an app is a lot for some people, and a monthly subscription seems much more manageable.
We introduced subscriptions for Android late last year, and the response was encouraging. So now we are offering subscriptions for iOS as well.
Subscriptions are an alternative to app purchases. Either you buy the Universalis app and don’t need a subscription, or you download the free Catholic Calendar app and subscribe.
