Lots of Ad
Ad so much that I can’t even use this app！
错误bug
我购买了去除广告，但当我重新下回来时，显示我没有购买
Doesn’t Scale!! Impossible to use on iPad
This doesn’t scale and I can only use the half of the app that is visible. I wasn’t a dollar thinking that would fix it and I was wrong. Don’t bother with this!
Their logo looks like a bong
The logo looks like a bong I think that’s pretty cool
Inaccurate information
I just downloaded the app today. The first element I clicked on in the periodic table was Oxygen, and was presented with information on Fluorine. When I clicked on Fluorine I got information on Oxygen. Makes me concerned about the accuracy of the rest of the data in this app.
Just awful
A lot of ads, can’t even use the app. Also, some data is very inaccurate and misleading. I won’t recommend trusting this app with science
Pictures?
How am I supposed to take pictures on this app?
How do I scan and take pictures?
I just downloaded the app but I can’t even work through the app without being bombarded with tons of ads. There’s is n option to get rid of them for $1 but I see everyone talking about a tool where we’re able to scan and take pictures to get explanations of problems...are we talking about the same app here? I’m very lost and on the urge of just deleting it.
