I am truly addicted to this app. I understand that this is an educational app, but I cannot go a day without it. Those first couple of days were so intoxicating as you were rewarded after every lesson, you were given points to compete against others, & you were gifted the ever addicting, "streak." Now, even after 7 months, I get a little rush from the ring after completing each lesson, as if I were a pavlovian mutt. However, there are days when I forget, but Koji is right there to reel me back.

This app really makes learning fun! I picked it up mainly to relearn all the algebra I forgot in highschool so I could in turn learn more interesting subjects. the methods are very engaging and I feel like I'm learning more quickly than I did back in school and I'm having an easier time grasping the concepts. I've branched out into other topics the app covers and I'm having just as much fun with them too 😁

Sometimes locks up, screen goes blank, and you have to relaunch and navigate all the way back through the lesson to get back to where you were. Subscription price is too high for what you get. Poor performance over cellular network, almost certainly from network activity on the UI thread. Good concept, but lessons and app implementation both need work. Advertised on basically every science and technology YouTube channel, but sadly the execution is very mid.
