Flashing color light source app for iPhone — screen + torch, built-in and custom effects, fully offline.
CrossSafe helps pedestrians cross dark, poorly lit, or high-speed roads safely by turning their mobile screen into an eye-catching, high-conspicuity emergency strobe flasher (alternating red/blue police cadence, split strobe, white/amber caution, SOS ). Once loaded or saved, it requires zero cellular data, zero Wi-Fi, and no app store download.
