Beware
The app took my money, didn't deliver the credits, and the support email doesn't work. Apple refunded me because nothing was provided. The developer's response ignores this - the app charges you and doesn't deliver. AVOID AT ALL COSTS
Response from developer
This claim is false. VintSnap never receives your card details — Apple processes every App Store payment and doesn't share card data with developers, on this app or any other. What you likely saw was an Apple charge ("APPLE.COM/BILL"). Refunds take two minutes at reportaproblem.apple.com.
