Strong Points: Easy-to-use conversions, good scientific calculator
Weak Points: Limited features in the lite version of the app


Free (in-app purchase to full version for $9.99)


As it is designed to look like the Calculator app intrinsic to iPhones/iPads, the utility of the PCalc Lite app is perhaps not obvious at first glance. However, upon closer inspection, users will notice the added functionalities that even the free, “lite” version of the app offers. In addition to offering standard features of a scientific calculator like logarithms and exponentials, the app features a small collection of basic constants, such as the Planck Constant and approximations of pi and e. It also includes a number of unit conversions for length, speed, temperature, volume, and weight that are very convenient to use. The lite version of the app is useful; however, (as the app will remind users) there are additional features that are only included in the full version of the app.
