Turn your iPhone’s rear LED into a flashlight with a clean charcoal screen and a vivid mint symbol. • Tap the symbol to turn the light on or off. • Swipe up or down, or use the settings slider, to adjust brightness. • Touch and slide across the dots to change the blink rate as you move. The dots fill from the left. • Choose steady light or blinking from 1–25 Hz. • Choose whether to show the status bar and prevent auto-lock while the light is on. • Smooth transitions and VoiceOver labels. Requires an iPhone with a rear LED flash and iOS 17 or later. The LED stops when the app becomes inactive. Actual brightness and blink timing depend on the device and its temperature. Extended use can consume battery and generate heat. Avoid blinking light if you are sensitive to flashing lights. This edition includes banner advertising through Google AdMob. No account is required.
