Gesture-Based Calculator Solves Equations Three Times Faster [Video]

Gesture-Based Calculator Solves Equations Three Times Faster [Video]

A simple app uses intuitive finger-swipes to quickly calculate maths problems.

The Rechner iOS app is the world’s first calculator that replaces common operators like the addition, subtraction, and equal signs, with intuitive gesture controls. Users can perform simple calculations by simply swiping their finger across the screen, which effectively speeds up the process by 200 percent.

To use the Rechner calculator, simply swipe left to right is for addition; right to left for subtraction; upwards to calculate; and a two-fingered swipe to clear the screen. For multiplication and division, however, users will need to bring up the hidden actions drawer to find the button. Watch the video below for a demonstration.
