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!

Hands down a quality educational must have. Clean interface, easy to understand, Truly free to use, and Made for everybody. I Downloaded this app to brush up on my math before I enroll in college and it has been a blessing since I started. Lessons are easy to find and organized as well as there being a number of intro lesson plans to help anyone pick up wherever they left off or for the first time. Best practical app I've downloaded in a long time

I was so excited to find this app. I've always wanted to learn about a lot of different subjects and now I can/am! Some of the ancient history time line is a little off, it's based around the Christianity/religious timeline. (Which I thought was super lame.) I was super impressed with how much education app has to offer. It's not all just boring, having to read 50 pages in order to finish one section of a section. You go by your own pace of course. Highly recommend.
