CalcBox offers a $0.99/month auto-renewing monthly subscription and a $9.99/year auto-renewing annual subscription, which removes ads and allows users to choose additional app design themes while maintaining an active subscription.
Payment will be charged to the credit card connected to your iTunes Account when you confirm the initial subscription purchase. Subscriptions automatically renew unless auto-renew is turned off at least 24-hours before the end of the current subscription period. Your account will be charged for renewal within 24-hours prior to the end of the current period, and the cost of the renewal will be identified. You may manage your subscription and auto-renewal may be turned off by going to your Account Settings after the purchase.
