FlickerSense
Turn your iPhone into a professional light flicker detector
What it does
FlickerSense turns your iPhone into a light quality analyzer. Using 240 FPS camera capture and FFT analysis, it detects invisible light flicker (50–120 Hz) from LEDs and fluorescents linked to headaches, eye strain, and focus issues. Also measures color temperature (Kelvin) and brightness (lux). Built for people with light sensitivity, ADHD, epilepsy, and anyone optimizing their environment. Free unlimited scans. Premium adds trends, blue light analysis, workplace compliance, and export.
