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

Patterns at a glance

A call, a message,
an SOS.

A call blinks until you answer. A message blinks the number of times you set. The flashlight tool can send SOS. With Pro, every app can have its own pattern.

  1. Call: blinks until answered (dashed line)
  2. Message: three blinks
  3. SOS: short, long, short

Privacy

It sees which app.
Never what it says.

FlashNudge uses notification access only to know that an app posted a notification. Titles and texts are never read, stored or sent.

No accountOpen the app and start. No sign-up, no password.
Ads you controlThe free version shows Google AdMob and Unity Ads, asks for your consent where the law requires it (Settings › Ad privacy choices), and never gives them your notifications or your call state. Pro removes every ad.
No notification textOnly the app and the kind of notification are used, at once.
No numbers, no call logThe phone permission only tells it that a call is ringing.
What leaves your phone
Only what the ad networks in the free version collect: the advertising ID, device and app information, ad interactions and an approximate location from your IP address, never your notifications or your call state. Payments are handled by Google Play; FlashNudge checks your purchase on the device. Gizlilik politikası →

Questions,
answered.

Can FlashNudge read my messages?

No. It looks only at which app posted a notification and what kind it is (a message or a call). It never reads the title or the text, and stores and sends nothing.

Why does it need the phone permission?

Only to know when a call is ringing, answered or ended, so the flash starts and stops with the call. It does not read numbers, contacts or your call log.

My phone has no camera flash. Can I still use it?

Yes, with the screen flash (Pro): a coloured full-screen pulse. Android asks you to allow display over other apps for it.

Will it drain my battery?

It sleeps until a call or notification arrives, and the battery cutoff stops flashing below the level you set.

Which Android versions does it support?

Android 7.0 and later.

What do I get for free?

Call flash until answered, message flash for your SMS app and 3 apps, speed and count, ring-mode and screen-off rules, battery cutoff, test and the flashlight tool. The free version never expires; it shows ads, and Pro removes them.
