Calcbot is a universal app and it works perfectly on any iOS devices. It supports sync function so you can access your saved values, expressions, and calculations across different devices.

To get started, just install the app and open it from the application list. It opens the standard calculator by default and you can use it immediately for basic arithmetic problems. One notable feature of this app is the addition of a favorite key in lieu of the usual memory function. So if you want to save something, just tap the favorite key and it will be stored in the app.

The tape shows previous calculations as well as stored values and expressions. It allows you to use previous expressions for faster calculations. You can also use it to cross-check typed values to avoid typographical errors.

Turn your device into landscape mode to open the scientific calculator. The app supports all key scientific functions including basic statistics, trigonometry, and atomic mass.
