Usefull but not fully satisfied If I zoom one box of element on screen,it should be clearly visible. It's not a game that needs storage access to save progress,so I don't think it needs such a permission ,that makes it untrusted app.Internet use for ads is ok.Thanks. For now periodic table by JQ Soft is best.

Great App ...although I'm not sure some of the pronunciations are correct: Roentgenium, for example... and Livermorium and Flerovium need pronunciation updates. Also, when taking a quiz, it should show your keyboard automatically instead of forcing you to touch the blank each time. It should also accept alternate spellings and names for elements and tell you what you actually typed in the blank when you answer one incorrectly.

From a science "newbie" I never took physics, or chemistry, in school, and in my life, I've missed that, because metallurgical studies absolutely require it. This app has a tremendous amount of information contained in it, and the teaching videos are not just entertaining, but they'll make you think, so even the "geniuses" out there could learn from it (at least I think so). It's worth downloading for your device!

Chem nerd Queen Hey guys, absolutely ADORE this app, I use it to pronounce the elements correctly. The voice feature that helps with that doesn't have the right names for the recent update... If you guys could fix that, I'd greatly appreciate it! Thanks for making this app, absolutely worth downloading!!!

It would be the best educational app if some changes are made When ever I click for viewing the atomic mass or its details i need to click 3times and view it zooms it too much it should be changed

Excellent just a few problems Great app but it says helium as discovered in 1895 but was actually discovered in 1868. And as you near the end if you ask it to say the name of the element it says the wrong name. Other than than that it's a brilliant app.
