ilin Smart Home vs FutureCalc: ergonomic calculator for single-handed use使用状況と統計

FutureCalc is an ergonomic calculator, possibly the first of its kind, specifically designed for single-handed use. All buttons are accessible for the thumb without repositioning the phone or supporting it with the other hand. Two layouts are available to choose from: we call them Radial and Concave. Each can be flipped for either right or left hand use. Features: - No equal sign: the results are displayed "on the fly", so no need for an extra tap. - The basic set of arithmetic operations: addition, subtraction, multiplication, division; the internal format is 64-bit floating point. - Flip the keypad for use with either left or right hand using the button with two arrows. - Switch the designs using the settings button at the bottom. - There is only one CLEAR button: tap once to delete a digit, or tap and hold for a second to reset the calculator. - Copy/paste supported: tap on any of the displayed numbers; the editable number allows copy and paste, while others are only copyable. - Maximum length for arguments in this version is 16 digits. - Works on all iPhones starting from 4S. The 6/6S design is adjusted so that the physical size of the buttons is the same. Enjoy your numbers!
