This app has a lot of potential. There are also a lot of small details that the devs have put attention in, like some animations, badges, etc. But I have some recommendations for them:
1. Fix the UI bugs for the fill in the blank questions. A lot of people, myself included, either have trouble or are completely unable to get the draggable blocks to fill in the spaces. For example, I’m currently unable to make any progress on the API’s course.
2. Rethink your font/icon size design. There’s a lot of text that’s too small, and some that are too big. The relative proportions are kind of off and it hurts the user experience. I think a lot of text in the nav bar and in the profile tab are way too small. I feel like I’m squinting sometimes, and I’m a 20 smth year old.
3. There are some other bugs with counting of stars and exp. But that’s not as much of deal breaker.
Thanks. Wish the best of luck to you guys!
