Woodsmall Inc. Calculator imbues your phone with powerful calculative functions. While most phones come with a calculator pre-installed, these are often limited and don't provide much to users besides basic additive, subtractive, and multiplicative functions. The Woosdmall Calculator greatly expands the functions available to users and provides them with all the tools they'll find in a modern retail calculator.

Options you won't find in a standard phone calculator app include percentage, constant, and exponential calculations. For those looking to deal with their finances, options are available to determine compound interest and other more complicated fiscal functions. Interaction is designed to mimic the style used by Casio brand calculators, so the transition for most users will be simple.

What Woodsmall sets out to achieve with their app is relatively simple, but they deserve credit for how intuitive and easy to use the calculator is. You can set up a floating widget or home widget so you can have easy access to it at all times. Calculations are saved even if you close the app in the process of making an entry, and they keep a detailed log of all your pass actions, so it's easy to check your work whenever you need to.
