## What is Inseries?

The smart, modern, and elegant calculator app - optimized for multi-touch
* Easy, logical entering of calculations and clear history of previous results
* Built-in calendar functions (e.g., number of days between two dates)
* Naturally adding and subtracting percentages (e.g., 99+20% taxes or 79-30% discount)
* Gesture support for fast access to previous results and memory

Inseries is the slightly different professional calculator app that allows you to naturally enter calculations and clearly browse your previous results. Simply type in "100+20%" to add taxes, or "100-30%" to easily calculate a discount. Inseries even shows you "pi" as a real constant instead of just a number.

Inseries' clear user interface is designed for multitouch allowing us to come by with a small and simple keypad based on the clear keypad layouts of typical financial and business calculators. By using choosers for quickly accessing functions and constants we could bring in scientific calculator functionality without sacrificing usability.
