About this app

More visible at night with your phone. Or let your phone flash the 1–4–3 (I LOVE YOU) light!

Use phone LED flash as a strobe light or flashlight.

Sound activated feature to flash to ambient sound (requires microphone permission).

Splash of colors. Flash the screen, alone or synchronized with camera LED flashes, with one or more colors.

Widgets support. Launch strobe lights with different frequencies from the launcher screen by creating app widgets.

Supports front flash, if any.

May be used as a coarse stroboscope, with limitations due to device hardware, on devices that support fast turning on/off of the LED flash.

Ratings and reviews

Does what it says. Adjustable frequency and duration of flashes. Being run by software on a phone using touch friendly sliders to adjust settings, it can be hard to get it perfect, and the timing consistency is not perfectly stable but it's fair enough to have some fun - this is likely a hardware limitation, no fault of the developer, but it seems to be less consistent than a "real" strobe light e.g. cannot get a spinning fan perfectly dialed in to appear stationary. Much better than expected.

It does what you want it to do without any hassle. Thank you to the developer. I personally used this while I was kayaking on the Hudson at night. I set this to blink at a specific frequency so I have a light on my kayak for other boats to see. Very little battery usage. It gives you the option to choose the rate of flash with frequency or flash per minute (FPM). It also let's you choose how long of a pause in between flashes you want and how long you want each flash to be.

During the strobe, the frequency of the blinking is not displayed. On the display with the adjustments, there are a half dozen virtual sliders and buttons, but they are not labeled. Lack of labeling makes using the app overly complicated. However, if you just want some blinking, this app will accomplish that. It really doesn't like to strobe 40 Hz. It will do a solid 39 or 41, your phone may vary.
