5★Really fun little app, let's you stretch your brain a little while not being too intense. I feel like if I rush I won't get the answers right so it kinda slows me down and helps me think. My only 'complaint' is that the number of free lessons for the day is pretty small. But I guess if my only issue is I wanna do more that's kinda also a compliment.

5★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.

5★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 😁

5★This is truly an awesome app! They obviously want people to buy Premium, but unlike others, they don't constantly spam you with ads. The ads are only for buying Premium, and they're funny. The amount of things you can learn here is incredible. The two keys a day limit is maybe a litttleeeee small, as the lessons take like 5 minutes, but its a fun brain teaser for a bit every day. I recommend it, especially for those that are just looking for a bit to learn every day.

2★Brilliant is a great platform, I'll start with that. It has been great up until recently. As of late, the app has been closing itself causing me to lose my keys halfway through a lesson. When it first started, I had seen an error message letting me know the app hung and needed to be closed. Now it almost always closes through the main lesson with no error, burning my key and not allowing any continuation. So i can't get my xp, cant finish the lesson and being forced to the bottom of leaderboard.
