This app is okay, I feel like you should really do something about the "hint" notification showing up as it really is a distraction. Also this app seems to be lagging a lot and working very slow. 😧 I really do enjoy this app but I feel like these features could be fixed up a little bit! ^^ Other than that this app is very well done the lessons really do help me and I really enjoy using this app! 😊
Facebook login doesn't work. Google login sends me to chrome and to this lovely text screen. Idk about the content inside but the app is not working properly. Since I'm rating the app and not the content, it's one star cause it doesn't work. The error code doesn't even fit here so yeah I can't add it -.-
Theives!!! Purchased this app and it never worked. Contacted these people on numerous occasions and they danced around refunding me my money. As of today, they have not refunded me! 😡
it is a great way of learning💆
this app let me know more about mt biology and my other class
very cool and the rest of things are good
Great high school study aid
Its nice to use and it is so usefull
Think it's very good app
Education is the best
Best app ever
Haven't used it but my school made me set it up so I hate it.
I really enjoy this app! Easy and fun to use. It helps pass the time and I'm able to brush up on my school subjects.
I get most questions right but it says I did it wrong and I use the hints and I'm doing it right
This app will assist in our curriculum planning for our Christian Academy. Very good app and design
Can't log in with Google account.
It a good app and it's very helpful.
I hate this app😈👹👺
Hint is the bad portion of this app
This app is the Best
I llike it but the ads
I like the app except one thing. The stupid "hint" window comes down every time a few seconds after the new problem loads, regardless if it is needed or not. It is distracting and teaches kids to depends on hints rather than give them the time to figure it out on their own. This makes it a poor design. Food this or give the option to remove the automatic drop down hint window and my rating will do up.
Helpful 4 me because I am in school and I don't have a computer at home so I can do my homework on this app on any of my devices at home. SWEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEET
The quiz portion is atrocious; the notification, “We have a hint for you,” continuously pops up ever 2-3 seconds after completing a quiz. Get rid of this notification! It's unnecessary, and it's a distraction!
Good just confusing it only went up to 5th grade
Best app for studying there is videos questions and all the concepts you think of. 👍👍👍👍👍👏👏👏👏👏
Its a very good app i am sad seeing less download.everyone should download it
Love it!
Its very informative,but sometimes when I put the answeres in it comes up incorrect. I check the answers and it has the same answer I put If you can fix that this app will be 5 stars.
I just hate the app, but due to educational purposes I had to downloaded it because the site doesn't work on my laptop. Its slow and the content is debatable, with some bias. Also reported me for "spam or unwanted content" when I reported a question. Some of their questions don't even have the answers in the text, so it's just a completely random question that's a "hard one". The hints are also completely useless; they are literally restating the question.
