S0S Light 对比 Delta Calc 的使用情况和统计数据
Activate the SOS Light with a single tap to send a distress signal in Morse code (three short signals, three long signals, and three short signals again). The app blinks the screen and flash accordingly, making your distress signal visible even in low-light situations. Stop the signal easily when help arrives or the situation stabilizes. Simple, effective, and potentially life-saving.
