Ten Timers

十計時器精確測量10個獨立的定時器（一屏/背景）

Ten Timers accurately measures 10 independent timers (one screen) and can run in the background. Good for track and field events, and basic time measuring. Start all ten timers at same time, and stop or start each one individually. This software uses a System.offsetmilliseconds and by doing this is independent of other apps that may throw out its internal timer. It does this by keeping a millisecond 'bank account' for each timer - making it accurate even if running in the background, or if the phone is frozen. Do note that the android OS can remove it from the background task if not refreshed for some time.
