Upgrade to full version – Timestamp Camera Basic Review

I upgraded to the full version on my ipad. Now it seems l have to pay again to get the full version on my iPhone. I've never experienced this before. I take most photos with my phone, which has a better camera. Am I missing something? If not, I want a refund so I can transfer this purchase to my Iphone.
