WHY ON EARTH IS THIS NOT MORE POPULAR??? Seriously, this is the first time I rate an app/share it with friends without being asked. This is great; the lessons are well made and well organised, there are soo many topics, and the memorization techniques are fun and work great! And it's free??? Woah The only complaint I sort of have is that there is not (or maybe I haven't found it) a simple button to share a link to the app to your friends. I love it, and I really, really recommend it :D

I'm in awe of this app. For years I've been looking for something that provides me with some value when I habitually pickup my phone. There are no adds, no purchases, no premium accounts. What you get is a tailored lesson in a subject you're interested in, presented in a perfect format for a mobile device, and delivered using the latest learning theories. Everybody should have this installed. Everybody. Less doom scrolling, more micro learning. If I could support this app, I 100% would.

Provides a good introduction to a wide range of topics, at a kind of university 101 course level. The fact that you spend a few minutes at a time on it means you're not overloaded, but it still throws a lot of new information at you in a concise way. Couple that with the regular reviews and you find yourself actually retaining most of the information too. I'm a big fan so far :)
