You can get a refund for most purchases on the App Store.
Apple do not share customer or purchase data with developers. We therefore have no knowledge of individual App Store purchases and cannot process refunds ourselves. Only Apple can process refund requests.
If you are unhappy with your Just Press Record purchase, we would genuinely be interested to know why. All feedback on Just Press Record is very helpful to us, and allows us to tweak the app as we continually update it.
