Ok, many people have written bad reviews. But I promise this one is true, I really promise. Over time, this app has fixed some bugs & issues, which helps the people now. this app has got some really good stuff & questions for all grades. It also has stuff that's not grades, like Algebra 1, Algebra 2, Geometry, etc. Like, amazing. For people who are in grades Kindergarten-8th, this is perfect. I'm a student, but OMG! Amazing. I can't even explain how good it is! One thing I love about it is, you can also do it on mobile. And PC. And on mobile, you can actually draw! You can use a pencil, and a highlighter. I have used this for 2 - 3 yrs, and I have loved it. I recommend this a lot. [ Edit ] Hi again! So, here’s my new opinion. Basically, this app can be very frustrating. I had used it today, and felt like ripping my hair out. Literally. I got so frustrated, and I was only testing out 3rd Grade! 3rd! this app, if your reading this, step up your game. You need to make this easier! I spent 20 min just trying. For 3rd, don’t forget. So, once again, I give this a 3/5. Sorry, but it’s the truth.
