Most comprehensive chemical data I’ve ever seen.
This app is extraordinary. Contains information on every element and their isotopes. I work in the nuclear industry and I find it indispensable. Only needs update for recently discovered and named elements. The Mac app is even better.
Not a periodic table
This "app" is just a list of elements sorted by their names. There is no attempt to display and allow access to the element data from a periodic table, let alone from a list sorting them by their atomic number (which would be the second best way.) An app should really allow searching of all the data to take advantage of the whole point of the computer in a tablet.
Also, while there is lots of data, there doesn't seem to be any way to copy and paste those values to other apps. A simple text document with this info would ironically be more useful.

Loads of data
This app contains an impressive amount of information. The only trouble is that you can only access the elements from an alphabetical list (which isn't very useful). If you could access the data from a visual periodic table I'd have given it a 5.
Excellent app
I have found this to be a superior reference as I am responsible as the public health planner for a district with a nuclear power station and the routine other man made sources.
Ok but....
Needs a visual interface to TOE (or TOI), and also has a bug where screen orientation changes after celecting back from isotope page..
Also some isotopes are wrong... Metastable states are missing, mostly identified as other isotopes (eg Al26m) as other isotopes..

Please add some more functionality
Not bad but could be so much better. Please add gamma decay energy, gamma ray constants and gamma shielding values and it would be pretty much perfect.
Great App - Very Handy
I used an app on my cell phone (Windows Mobile) that had considerably less information on each element. This has a lot of information in it.
Lots of info but gamma energies missing
I haven't yet checked for accuracy but cannot believe that gamma energies of isotopes are not included. I would think that to be a key item in the database.
Can't trust the data
The data on daughters and possible parents of isotopes are nonsense. For example, under iodine-131, the daughter is given as magnesium-131 and the possible parent lithium-131. Of course there are no such isotopes. Makes me wonder about the data I have not checked.
Good app if errors are corrected
I was glad to find an app with isotopic properties. Unfortunately most of the info on parent and daughter isotopes is incorrect (87Au is not the daughter of 87Rb, for example). Makes me wonder what other information is incorrect. App would rate 5 stars if errors were corrected in an update.
