Caught on tape. Calcbot features an expression view that lets you see you your calculations in real time, as you key them in. It also boasts a history tape that lets you refer to and even reuse your previous expressions and results.

Ready to convert? Calcbot is free to download, but includes a one-time in-app purchase worth $1.99 for unlocking its conversion functionality. Once unlocked, this functionality allows you to convert any of your calculations with a variety of units across different categories including currencies.

What is it about?

CalcBot is a polished, universal calculator app. The audio makes you feel as if you are operating an old school calculator, and the live history feature comes in handy when you need to go back and refer to something. You can look up previous calculations with ease. The calculations also display what you just entered, so you do not risk entering the same number twice. Plus, Calcbot works in both portrait and landscape mode with more functionality, you can handle conversions right from the app, and there are a handful of fun color themes to make the experience your own.

For those who...

  • Love Tapbots apps
  • Want a simple but efficient calculator
  • Also want to be able to do conversions

Not for those who...

  • Need to work with complex equations
  • Need graphing functionality
  • Don't care about Tapbots' apps

Why we love it

Calcbot was one of the original Tapbots apps, and we're glad to see it updated to reflect the modern iOS aesthetic while retaining some of its charm. For a simple little calculator, it packs in quite a punch and having the option for more functionality and even conversions is a plus.
