So don't get me wrong, I think the app itself is great, it has some good content and overall is well designed. What really annoys me though, is the constant reminders about premium. I know premium exists and I'll pay for it when/if I want to! Why do I need to be reminded every single day often multiple times!? If there's anything that will stop me using Brilliant, it's honestly the incessant reminders to spend money.. I really think it needs to be toned down a bit.

Really fun way to learn things! With the app, you get two lessons a day for free, unless you'd like to upgrade to unlimited. I've been learning scientific thinking, and it's helped me learn some basics of stuff all over that I wouldn't have thought to learn about. It's presented in an easy to understand way, and it's all interactive - which is a must for me. If I had the money, I would honestly pay for the subscription, but for now I've actually been pretty satisfied with just two lessons a day.

Meh. Leagues and streaks are not necessary or valuable. 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's something to replace doomscrolling for the five minutes it takes to use up the two keys for the day. Update: I found a section that is new to me (number theory) and it is great. I am glad I didn't have to "achieve" that level - I could just start it. Still wish there were more than 2 keys/day
