A Scam – Spectrum Analyzer: Sound Wave Review

You have 3 days to evaluate the app before being slammed into an in-app purchase. But no manual or help file to explain what you have 3 days to evaluate. Then the App Store sends out a notice about a subscrption started: "To avoid being charged, you must cancel at least a day before each renewal date. To learn more or cancel, review your subscription". And the link here goes unanswered. So the App Store is in on the scam. This could be a great app, but I'll never know.
