ATC Calculator (ATCCalc) is a utility for use in stage rally competition for calculating the arrival time for the next control. Time can be entered in minutes or hour:minute format. Hour:minute time is based on a 24-hour clock.The time values are displayed in a large format for easier viewing. The buttons are larger and separated to make it easier to select the intended button on rough transits.
What's new in version 2.0
ATC Calc 2.0 has the following changes:- It fixes issues that stopped previous versions of ATC Calc from working with iOS 9.- The buttons and displayed time values are presented somewhat differently in an attempt to make them easier to read in all lighting situations.- It replaces the black-text-on-white-background/white-text-on-black-background toggle with a slider that adjusts the "brightness" of the background, buttons and display. It does this by adjusting how gray they are displayed.- It scales the buttons and displays to match the size of the screen that it is being run on.There is one small problem noted on some devices. On these devices, the brightness slider will sporadically not respond when touched. This is only an issues on a small number of devices and is a small problem compared to this app not working at all on iOS 9.
