Recurring payment

I needed this app for an introductory graduate class and when I needed it I loved it. I had no idea it would be a monthly recurring payment. I am not using this app at the moment and there is no easy way to cancel the apparent subscription. While the app itself is great, I am very unhappy.

Developer Response ,

Thank you for the report. We think that you can cancel it from iTunes, but the current procedure is troublesome.
Regarding fee, we set it considerably cheaper than general one, but the troublesome of cancellation is a problem. However, for now, we can not solve this directly.

(Update: Cancellation is possible now from the App Store app. However, app developers, including us, can not cancel directly. Cancellation by the user is required.)
