2026-08-17BEWARE... Subscription renewal @ $50... fix that in your app and notify me and I would give this app the 5* it deserved. You've got to understand just because something is legal doesn't mean it's ethical. Automatic subscription renewal is not fair to consumers, in my opinion, it's a legal scam and should be against the law. App makers should rely on the strength of their service to be paid JUST LIKE EVERYONE ELSE!!!

2026-08-14This company is a scam- the reoccurring charge is astronomical and when you forget to cancel, they refuse to refund you. $82.95 for 3 months is wild. Especially when you haven't opened the app or used it. Don't fall for their free trial.. its garbage.
