Purchases and Subscriptions



Flippy Premium

Planny Premium is a single add on, that is available as one-time purchase or subscription. It unlocks all features. 


I bought Premium but it doesn't work

Every subscription purchase has to be validated by servers. Depending on your network provider's restrictions or usage of VPN this validation can fail. Please check everything before contacting.


Cancel subscription

Developers aren't able / allowed to build in a "Cancel subscription" button inside apps. Instead Planny features a "Manage subscriptions" Button inside the Purchases View. Else you can do the following:

  • Go to Settings > [your name] > iTunes & App Store.
  • Tap your Apple ID at the top of the screen.
  • Tap View Apple ID. You might need to authenticate your Apple ID.
  • Tap Subscriptions.
  • Tap the subscription that you want to manage.
  • If you're being charged for a subscription, but you don't see it in your list of subscriptions, it might be billed through someone other than Apple. Learn what to do if you still can’t view your subscription.
  • Use the options to manage your subscription. You can choose a different subscription offering, or tap Cancel Subscription to cancel your subscription. If you cancel, your subscription will stop at the end of the current billing cycle.

macOS App + Watch App



As soon as macOS 10.15 Catalina and watchOS 6 ship, Flippy will be available on the Mac as well for no extra charge
