Ratings and reviews

"Why does the 'Send' button appear instead of the 'Enter' button at the bottom right when the typing keyboard opens? When I'm typing or trying to add something to a new line, all the text ends up next to each other. This is a very inconvenient situation. I think you need to update this. There's already a 'Send' button (like an arrow) in the typing window. The ability to go to a new line by pressing 'Enter' must definitely be activated on the typing keyboard.

Overall it's a good app for learning, but because almost every exercise must be unlocked by buying the "PRO" extention, it's been really a horrible time trying to learn from this so called "learning app". As of right now I've changed Knowunity to a better learning app that actually helps instead of being a total cash grab.

The app is amazing! especially when I'm a struggling student who relies on AI yet unable to learn efficiently. Knowunity helped me do my actual quizzes and flashcards and let's me ask questions. But what disappoints me is the payments for Smart answers finding the rightful study notes, it's understandable yet quite unfair especially for a minor student who's unable to pay for educational purposes. Education shouldn't be used with money, let along for a year. I suggest to watch ads instead
