Be careful – Math. Review

I purchased this apps few years ago. The app made me update to its latest version. Guess what????? They are now charging me again in order for me to use the app. Really??? What a rip off. Please, be honest and don’t trick your customers. I also want to mention that the same thing happened with the GRE app I purchased. Now the app doesn’t even work!!!!!
