It is correct that many different price points for the same subscription model are displayed in the App Store. This is because Apple obliges all app providers to display all prices currently and previously offered - this includes all prices which have been offered in the past. We understand that this may be confusing as it does not mean that all offers are still available. Cheaper prices shown can therefore be special promotions from the past e.g. for the Christmas season.
Some of our subscription options may come with a 7-day free trial, however, a trial can only be redeemed once per Apple ID.
If you have any questions regarding our current subscription prices or offers, you may always reach out to our support team either via email at firstname.lastname@example.org or via the chat function in our App and on our website.
