I can’t continue either the app because it’s asking for me subscribe and when I try to it freezes and doesn’t let me move forward other than that great app extremely organized and helpful

Now, educationally speaking, this app is amazing. Step by step walk through, and honestly.. it makes math so much easier to understand. Been out of school over ten years, yet the app got my entire brain to understand every single lesson.The reason my review is only 3 stars is because I decided to pay the monthly fee and subscribe. I spend endless hours studying and doing the lessons, test, etc. Being that now I’m paying for the services, I’m annoyed when the app crashes. In the middle of a lesson, I am forced to close and reopen. Now, at this very moment, the app won’t get past the loading screen. So, I’m sitting here, and can’t do a dang thing. I’m just closing it repeatedly, and opening it repeatedly.. just waiting for the app to fix itself I guess. I was in the middle of taking test too, so definitely annoyed.Besides the failure in the app operating capabilities, the learning is good. The classes, chapters, lessons, etc are super helpful. In other words, the low stars is because of the functionality of the app… not the information from the app. Worth the subscription tbh, but only once the app is fixed!!!

I’ve been studying to retake the math portion of the TSI and this app has been giving me clarity in every area I was a bit rusty in. Definetly would recommend for anyone trying to relearn high school material to get into college level classes!

I finished final exam and want to check the answer which needs to subscribe to see, but the button doesn't work, said the purchase identifier was invalid. Can you fix it? I'd like to pay for it.Update: the new version fixed now. Thank you.
