As someone who loves reading and learning Im now obsessed with this app. Yes, it costs a couple bucks a month, and you can learn whatever you want online for free, generally, I find that this app guides you in new directions you previously may not have went and offers really great quality videos. Going off that, Ive generally never been much of a video watcher but this app has changed that.
I really enjoy the categories that the app offers and you get specific points for learning through different ones. I think this point system gives you a great sense of progress and also ushers you to learn in different fields.
They also have these really cool mini-article/factoids called "curios" that they write every day that are often humorous, entertaining, educational, and often make great stories to share with others.
Only things that I think could be improved upon would be more organized searching for things and more ways to search and sort through older Curios.
All in all, if you like learning and want to be a renaissance man, I highly recommend this app!
