Very worth it
This little program is well worth its money if you need a nice little periodic table.
The only way to make it better would be a way to enter additional data for the elements.
Since I do a lot of NMR-Work, the NMR frequencies of the NMR active isotopes and their magnetic spin would make this little app perfect for me.
Maybe pressing long on an element could bring up additional information (even a place to enter some own additional information would be great).
