When I first got the app I thought it was have a subscription or ads, but it had neither. This is very surprising for the amount of content that they have and how easy it is to use the UI. Sadly they’re missing about half the AP’s and the app has a hard time sinking data. Honestly tho, it’s a great app and so far has been great to use for the Ap exams. I highly recommend it, good job devs on making this and thank you for making it free (like genuinely thank you, you saved me soo much study time)

One of the best apps I’ve used for studying, has zero ads and isn’t promoting a special subscription every couple minutes. Genuinely amazing, contains immense amounts of study material for all sorts of ap classes! 10/10 definitely recommend

This a great app for studying before a test and it's legit. You don't have to pay for anything and there are zero ads unlike other studying apps that make you pay for everything. I was skeptical at first because nobody was downloading it and there weren't many reviews but it is extremely useful and I am happy I downloaded it. :)
