i continuously typed in my email and password correctly but it repeatedly said "invalid password or email, try again" I did try again, I even changed my password and re-entered it, but it was a complete waste of time, I expected to get more videos in the app and that's why I searched for it in hopes I could get the lessons I required but it failed me.

I absolutely love this app, I am now able to study even when away from my laptop. The ability to download videos makes it even better, the app is easy to understand and runs really well, it's encouraging to see my progress as I complete each lesson and the lessons themselves are beyond helpful. I do miss the playback speed feature, but given how amazing the app is I can hardly complain! Thank you so much Kevin! You've helped me in so many ways! May God bless you!

Kevin is amazing! He really saves lives. 10/10 !!! Totally worth it. Only one bug: I just found a problem on using downloads when you do not have any internet? It seems as if I cannot access my downloads/ i get kicked out of the app when offline.

Hi Rheba, this issue has now been fixed. You will need to do an app update.
