Maybe it's because I'm trying the free version? Maybe it's because I'm on Android 15. Whatever the reason is it does appear to take several attempts to load the first lesson of the day. It always reports that things appear to be taking too long. Not a great incentive to move to the paid subscription version. My bad. The impression I have is that the free version allows you one lesson per day. After that lesson is completed no more will load. I'm thinking I'll uninstall the app.

Thanks for letting us know — that definitely shouldn’t be happening. While the free and paid experiences should load equally reliably, we’ll flag this for the team. If the issue continues, feel free to reach out to support@brilliant.org so we can help troubleshoot. We appreciate your patience!

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 made me learn so many concepts easily that is essential for my studies! I will recommend every student/learner to download this app! If you're worried about the subscription, recently(or few updates before) they've unlocked all the courses for free users too! Just a downside is that you can learn 2 lessons per day as a free user and cannot jump ahead/skip , but it's still better than nothing! Go ahead and dive deep into the concept!
