Chemistry Helper (developer: Adam Hogan)

  • Many different features, covering general and organic chemistry
  • Periodic table is cumbersome on phone screen
Platform: Android Phone  
Cost: Free

Here’s a chemistry app that provides much more than a periodic table. (And actually, the periodic table that is included is one of the weaker features of the app, as it cannot be re-sized to fit on the screen.) This is primarily a “useful tables” app—there is a table for the charges of common polyatomic ions, a table of physical constants, and a table of solubility rules. In addition, there are tables for IR spectra and H1/C13 NMR shifts. However, this app is not just lists and tables of useful information. There are some very useful organic chemistry resources, such as diagrams of various functional groups and an organic reactions quiz. Unit conversion tools and solution calculators round out the major aspects of this app, making it a fairly comprehensive chemistry resource.
