A scientists best friend

Perfect for dimensional analysis because you can type in both values and units - for example,
25 meters/seconds * 3 minutes * 60 seconds/minutes

Great for calculating total number of samples in an experiment - for example,
Levels of temerature: 3
Levels of salinity: 2
Replicates: 8
Line1 * line2 * line3

Syncs saved files among iPhone, iPad and Mac - which is great when you have some formulae that you frequently have to use.
