iLlumination — 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. No ads. Just light, done properly. 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. For bug reports, feature ideas, or to help translate the app into your language, email me: iphone@erikstorli.net.

Verdict

The call

The clearest difference is price: OffBlock at Free against iLlumination's $3.99. OffBlock also leads on rating (4.7 vs 1.0) and ratings volume (102 vs 1). iLlumination's advantage is review sentiment (90% vs 48%) and in-app purchases (none vs 4). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

OffBlock holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: OffBlock has 102 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 90% of iLlumination's written reviews are positive against 48% of OffBlock's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 2 months. The most recent releases landed on October 13, 2026 and October 11, 2026 respectively.
