Paid

Paid with the promise of a one time fee, but doesn’t work anymore without a yearly fee.

Got bamboozled

Paid for this “lifetime” app years ago now it’s locked behind a subscription paywall… at least offer people who bought the app a lifetime option vs subscription. Totally lame.

Won’t live up to their policies

So I bought this, actually bought it and now they’ve gone to a subscription model and won’t honor their old purchases. To me, that is reprehensible. If people get their new subscription, who’s to say they won’t change that as well? Do yourself a favor and go get another program, or just look on the web. This company isn’t your best bet

Scam

Paid for lifetime subscription, then they turned it off for over a year. When it returned I need to pay again.

Terrible policy change

Bought the app in 2021. No subscription required. Now they locked previous users out until they purchase an annual subscription. Not part of the original agreement. Bye.
