A little more than 3 years ago, I used this app to learn the names and symbols of the elements, and it worked well. Recently, I downloaded it again to help me re-learn the elements, but when I pressed the crown, it froze and showed me a white box-ish shape in the top left corner. I deleted the app and tried again, but when I pressed the crown, it froze once more. I'm not sure who to ask for help, but I'll probably just erase this app and find another chemistry app.

First review I have written out of 200+ apps I have. This one deserves a five star review and comment. That being said, This cute little app gets my thought process flowing in the morning and assist with function of my motor skills (cuz I gotta use my thumbs and fingers and stuff to play... Oh, eyes help too... I couldn't see the screen if I didn't have that sense haha /end rant). I must be a complete nerd. I could think of better ways to get my heart rate going in the morning... After all, I do have a hot wife oops screw the game review I've got something to do.

When I saw this app my first thought was...oh...well I already know my elements. I'm a university student and the elements were not a challenge. Not for me...another student in my class wasn't so hot at it though. I downloaded it and played a few times with her.She did so much better with a bit of tutoring and this app. It was a great refresher for her and keeps me sharp.

This app is my favourite app ever (that's saying a lot!) because its simple, fun, and taught a 13-year-girl who knew nothing past Hydrogen, most of the elements. I played this with brother, who adores the Periodic Table, and we played for hours on it, laughing and learning. Who would have thought a simple quiz could teach you so much?I love this. Would have paid $5 for this, but its free! Get it. You will not regret it.
