WHAT IS IT :: A power failure monitor with audio & visual alarm.

WHO IT’S FOR :: Everyone that needs to be awake in an event of a power failure.

WHY IS USEFUL :: Will wake you up when sleeping. Handy in areas with tornados or earthquakes (usually power fails before the tornado).

Just insert the charging cable and press the big circle. The moment the power fails it gives you an audible & visual alarm. You will definitely be awake even if your sleep is deep. Press “TEST” it and see for yourself.

And when the power is off, the flashlight is there in the same screen for your convenience, in order to navigate in the dark.

Just what I needed


With baby chicks under heat lights, a delay getting them warm after a power failure could be deadly. I needed something simple. I just need to know when the power goes out. Nothing more. In this remote setting, any time the weather changes, the power can go out. This app allowed me to sleep, knowing my chicks were warm and safe. Thanks!

Cool but,


This app is convenient and useful however it does not work for my lock screen. I turn the app on, plugged in to power, set app to detect then wait for my phone screen to shut off. I unplug the phone and nothing happens. I put in my passcode and it works. So this is it helpful when sleeping worried about power failures.

Developer Response

Dear Subaru13WRX,
I have just noticed your review and many thanks for your download!!

The intended use of the app was not to monitoring any power failures when app was in background.

As more and more users are asking for this feature I will update Black Out app and I believe in two weeks time you will be able to download an updated version including this feature.

Thank you very much for your comments!

Just what I needed to sleep


At times with a lot of rain this is exactly what I needed to sleep. With the sump pump going off every 45 seconds, I needed to know if we had a power failure, so I could hook pump up to a generator so water wouldn’t overfill and flood basement. Thanks!
