There are limitations in the in-app purchasing where the StandUp Test cannot be transferred between the paid and free version of Instant Heart Rate. The paid and free version have an unique app ID on the iOS platform. We have discussed this manner with Apple and we are working to come up with a solution to this matter.
The StandUp Test is not currently available on your device. We are working to integrate the StandUp Test in future versions of Instant Heart Rate for Android.
