User reviews

Scam. Doesn’t Work.

Stay away from this app. It is a scam.

First of all, it is hands-down the worst designed app I have ever used, even including free ones. This app not only looks ugly, but its functionality is hilariously difficult. It's as if the developed intentionally tried to make the user experience as frustrating as possible. Do you want to memorize a stack? Okay, first open up a text file and manually type in all the cards, then upload the text file to the app. That is not a joke. There is a menu bar at the bottom of the screen. Do you want to hit any of those menu bar buttons? Good luck. They're incredibly tiny and you'll be trying to hit them over and over and over, hitting the wrong buttons many times in the process.

Oh, and did I mention that the app is buggy as hell and glitches out all the time?

And now for the best part. The developer, Ralph Cos is a thief. I paid for this app. It was a one-time purchase price. Yet now I go open the app to find that it no longer works. Ralph changed it to a subscription. Not for additional, new features. No, he locked it down for even the basic functions I already paid for.

It was already a garbage app to begin with, so I'm not even upset that he stole my money. But stay away from this terrible app and its scam artist developer.
