The app won't load the practice sessions for the first level of math. I tried over multiple days to work with support to get past it, but while they acknowledge it's a problem, there's not a lot of interest in fixing it. I'm really glad there was a free trial, because if I'd actually paid for this, I'd be angry. Edit: I got the practice sessions to load by multiple un/reinstalls, but then the app interrupted what I was doing to beg for a review. Here's my review: don't do that.

This app is awesome. It's helped me understand math and science easier than school did, including college. I like that they have the same bite-sized and gamifid approach as Duolingo. However, I feel as though it could provide more engineering courses: electrical, nuclear, and aerospace, just for example.

I love this app. The content is easy to digest, the learning sections are a perfect length, and they added a gamification aspect with leaderboards and streaks. I understand some computer science topics that never really clicked for me because the app developers design the material to be visually appealing, engaging, and simple without sacrificing the important concepts at hand. I'm really looking forward to going back through the math courses
