Product tour

See every call
with a flash.

The camera flash blinks while your phone rings and when a message arrives, so you notice it even when you can't hear it. No account. Free with ads; a one-time Pro removes them.

Calls

Flash while it rings,
stop when you answer.

The flash blinks for as long as a call rings and stops the moment you answer or decline. Useful in loud places, with the phone on silent, and for deaf and hard-of-hearing people.

  • Starts with the ring, stops on answer
  • Rules for ring, vibrate and silent mode
  • Only when the screen is off, if you like
for a flash.

Messages and apps

Pick your apps
for a flash.

Your SMS app plus 3 apps you choose flash for free; Pro adds any number. FlashNudge sees only which app posted a notification, never what it says.

  • SMS app + 3 apps, free
  • Pro: any number of apps
  • Notification text is never read
on, off, repeat.

Patterns

Your own rhythm:
on, off, repeat.

Set the blink speed and the number of blinks. With Pro, give each app its own pattern, use Morse presets, or repeat until you look at the phone.

  • Speed and blink count, free
  • Pro: a pattern per app, Morse presets
  • Pro: repeat until seen
at night.

Quiet hours

No flash
at night.

With Pro, set quiet hours and schedules, and skip the flash when the phone lies face down or the camera is in use.

  • Pro: quiet hours and schedules
  • Pro: face-down and camera-in-use rules
  • Pro: flash when an alarm clock rings
stops when low.

Battery

Battery smart:
stops when low.

Choose a battery level below which FlashNudge stops flashing, so a long day doesn't end with an empty phone.

  • Battery cutoff, free
  • Flashlight tool: torch, SOS and strobe
  • Pro: screen flash in your colours
