iLlumination US — The Classic Flashlight, Reborn The flashlight app thousands relied on is back — rebuilt from the ground up for modern iPhone. Same simple idea, a completely new design, and every feature refined for today's devices. Why fumble in the dark? iLlumination turns your iPhone's LED flash — or its screen — into a fast, reliable light, with proper controls for the moments you actually need them. Lighting modes • Flashlight — instant, ultra-bright steady light. • Tap mode — press and hold to shine, release to stop. The fastest way to signal. • Strobe — rhythmic flashing with selectable speeds, from slow to ultra-fast. • Morse code — type any message and flash it with correctly timed pulses, with a built-in SOS and loop. Choose your light source Use the LED flash, the Screen, or Dual (both at once) in any mode — pick a default in Settings. Built for control • Brightness — fine-tune the LED level and screen brightness with a slider, or swipe on the screen light to dim it on the fly. • Color picker — eight screen-light colors (white, warm, amber, red, green, blue, violet, pink). Remembers your last choice. • Screen lock — dim the screen and lock it so a stray tap never kills your light. Double-tap to unlock. • Auto-on — switch the light on the instant the app launches. • Dark, Light & Auto appearance. Strobe lighting can trigger seizures in people with photosensitive epilepsy. Please use with care. Note: Sustained use of the LED flash will drain your battery faster. I'm always improving iLlumination and I genuinely read every message.
