Absolute money grab
You have to subscribe to enable iCloud syncing. You give a lame reason why you need to charge subscription pricing for iCloud backup when every other app that I know of does not charge for iCloud sync across all devices. Goodnotes, for example, is one of them. Absolute money grab. This should be a one off purchase if anything. Continually paying you for syncing my data to servers you do not own is absolutely ridiculous and unjustifiable.
