it's a phenomenal app! I use it as an adult woman who thought I hated math but turns outI lacked practice and consistency. this app gives you both! the layout of each subject unit is great. it reminds you to come back and use the app with an notification in your email i like that feature a lot. it's free. I don't know how it's free. but I'm very thankful it is.

I'm a dyscalic adult trying to relearn my math skills. I'm really impressed with the detail it goes into explaining the concepts. How I was taught was mostly rote memorization, but this actually teaches the concepts. I'm still exploring the app, but it looks like it can easily be scaled up or down depending on a learners level and there's a lot of subjects. Great for anyone trying to teach as well. I think the app is a little ugly and not always user friendly. I'd give it 4.5 stars if I could.

It's pretty good but.... I wish their was an option to have it read things out loud to the kids, like a little speaker button so it's optional. It would really help my kiddos and me. So far he can only do math on his own unless I can sit and read it too him, which isn't always an option. Also the patent dashboard needs an easier layout. I would also appreciate the option for a 4 digit pin for my kids to log in. And make the app on chromebooks work better. Other than that we love it!

It's great. I am using it to brush up on Grammer for my field of work but I found much more. Upon exploration, I found useful learning concepts for both my children and myself in mathematics, history, science, arts and humanities. After going through a few videos, I see that they focus on multiple learning styles. Each video has traits of visual, read/wright, and auditory. After the video, they provide quizzes for hands on. It's an amazing resource for anyone wanting to learn.

I like it, especially if helping me relearn math I forgot. Unfortunately, it's extremely buggy and actually makes me really angry to have to deal with it so often. Sometimes when I leave a math exercise and come back later, none of the exercises load for the longest time. This wasn't a problem when I started using this app back in October, what the hell did you guys do to it? Also, can't use a hint during a quiz or unit test without it crashing. Please fix these issues because it's really difficult and frustrating to deal with.
