From the app’s Settings screen, tap “Premium Service”.
When you subscribe to Premium, ads will no longer be shown and you can use the app without ads during your subscription period.
Premium is available as a monthly or yearly subscription, and it will automatically renew until you cancel it.
If you previously purchased the one-time “Remove ads” option in an earlier version of the app, that entitlement remains valid.
You can continue to use the app without ads at no additional cost, even without a subscription.
If ads appear again after changing devices or reinstalling the app, open the Settings screen and tap the “Restore Subscription” button.
As long as you are using the same Apple ID, ads will be removed again without any additional payment.
