Great app, lots of room for improvement.

First, I’d like to acknowledge the AI use. One of the first pathways I started had an AI image, and I started to have doubts. However, I explored other topics and found that they mostly use public domain images. I understand there is only so much they can do with copyrighting and images, so I can let it slide.

Recently, I was working on learning about Greek Philosophy. As I got about 20% in, I got notified that the pathway has been updated and I would have to start over if I wanted to get the update. This is frustrating because 1.) I had to redo topics that didn’t change at all and 2.) I am now unsure if anything I am learning is 100% true, as they can get updated to be “more correct” at any moment.

I really love the app and want to keep using it, but now it is hard because there is a chance what I am learning is incorrect.
Besides that, I love the flow of everything and think the quizzes are a great idea. A big problem I have with the quizzes is they seem to be focused on unimportant facts or just the names of things I have learned. It’s a great help in recalling the name of an idea or person, but I struggle to actually explain what the topic is.

Wonderful!🎃📺

I am a teen and I have been using this app and it has improved my knowledge of WW2 and skin which is what I’m interested in and I have learnt so much and instead of just fact they give us real learning and make it fun by choosing your own pfp and unlocking pfps by completing topics and I would highly recommend this for anyone who has a curious mind!(I sound like a parent 🫩✌️)

Great app but content could be a bit better

Just needs better wording for the textual content. Content in some modules are repetitive, saying the same point again with slightly different wording which detracts from the apps purpose to deliver bite sized learning. Great concept and experience otherwise though

Underrated

This app genuinely has interesting topics to explore in. How come have I never heard of this app before!? This app needs more recognition.
