I've only completed a few courses, but it's great I love the fast pace questions and the short to the point lessons that go with them. It's not to difficult but you still get a good grasp on the subject and phrases questions an rephrases missed one's perfectly so you still have to have good comprehension to pass. also must mention the rewards are nice too

I don't like it. For one the font in learning is very large with no option to adjust, which increases cognitive load as constant scrolling is needed. Also the "learning" is just a dense summary of the topic, text only, then a bunch of multiple choice questions. Some of the questions are not covered at all in the content, many others have obvious "serious" and "joke" solutions. There's a lack of diagrams or formatting. Just don't think it's a good way to learn things.

I personally love the app, When I have something specific I want to look into, it teaches me what I'm curious about, and if I'm not sure what to learn, we'll the general curriculum Bring me something and teaches me things I wasn't sure I knew. The app is great, and the AI is extremely user-friendly, my only downside is it would be nice for there to be an option where we can possibly make the highlight "words" option a contrasting color so it's easier to read, over all I love the app :] 👏🫶,
