Tapbots, developer of the popular Convertbot and Pastebot apps, has released a new universal calculator app for the iPhone, iPod touch and iPad. Calcbot is a simple and intelligent calculator that includes advanced functions and calculation history features. The application sports the same general design aesthetic as Tapbots’ other apps with an elegant yet simple user interface that includes animation and sound. Calcbot provides a live as-you-type expression history presented as a calculator tape view that shows all figures and expressions; users can also e-mail their calculation history as text or select values and expressions to send back to the calculator. The iPhone 4 Retina Display and iOS 4 Fast App Switching are also supported. Calcbot is currently available from the App Store for $1.
