Time Calc and Countdown

TimeCalc and Countdown is a time calculator that will count down to the calculated target time.

Time can be entered and that time added to or subtracted from. That time is compared against the current time and a countdown (or count-up once that time has passed) is shown.

Since a target use of this app is to countdown, the time is presumed to be before the current time. For the purposes of the countdown, a time value before the current hour and minute is that time on the next day.

Tapping '=' locks the target time. The '+', '-', and '=' buttons are disabled until the 'C=' button is pressed.

What time the app thinks it is can be changed by tapping the Settings button and adjusting it there.

Use of the app is intended to be intuitive. If your intuition does not seem to match our intuition, let us know.
