Yes, you can restore a subscription. Open the Zingeroo app, go to Account Setting -> Subscriptions. On the subscriptions page, you will see a “Restore Purchases” link. Follow the prompts from there. You may need to restore a purchase if you purchased it with your Apple ID a while ago, but the Zingeroo App is not acknowledging it. This could happen when you change devices, close your account and reopen another account, etc.
