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 😁

Meh. All the leagues and streaks are not necessary or valuable. It starts at the most basic level and it would take weeks just to get to something that would be new and challenging. I'm not a fan of the Duolingo style system, so this app, sadly, feels like a bust for me. Very intriguing, but once I start playing with it, it just becomes something to replace doomscrolling for the five minutes it takes to use up the two keys for the day.

Thanks for the honest feedback — we understand that the style and pace may not work for everyone. Early lessons are designed to build a strong foundation, but we’ll share your input on progression and motivation systems with the team as we continue improving the experience.
