I am a little app that reports any power outage or failure. Live, with alarm and email.

I can send you an email with useful details so to know what is happening, but first you need to make sure that an internet connection is live.

I live in iOS, meaning iPhones, iPads & iPods are my favourites! The oldest device I can live in is one with iOS 9.3.5, like an iPhone 4S. Just leave the device charging, set up your settings & press the blue thunder.

The rest, leave them to me. Happy to help!

• Has delicate electrical equipment that power failures might destroy them
• Has his/her equipment destroyed from power failures (e.g. fridges)
• Needs to be notified when power has failed
• Needs to know the duration of power failures
• Thinks safety is above all

• Will wake you up when sleeping
• Will send you an email when power has failed
• Will send you an email when power has been restored
• Handy in areas with tornados or earthquakes (usually power fails before the tornado).

Just insert the charging cable and press the thunder (electrical power symbol). 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. Will also send you email notifications

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

• Found a device no longer in use
• Found a working charging cable
• Place it on my lab with the delicate equipment (fridges, incubator, dehumidifier, etc)
• Connect it to WiFi or 3/4G
• Enter my email
• Adjust the Detection Sensitivity if I want to avoid micro failures (less than 3 seconds)
• Turn off sound alarm
• Start monitoring power failures
• In case of power failure it will send me an email and take action

*be aware that the device is in good working condition (ideally hold power & home buttons until you see apple logo before operation)

Saves our coffee truck from freezing

The app is working perfectly for our coffee truck. It alerts us if we have a power failure while our coffee truck is in storage. We can respond before the water lines freeze and before the temp in the fridge gets in the danger zone. I can now sleep at night when the temp drops below freezing. Thanks!

Developer Response ,

Excellent to hear that you saved your truck and that Black Out helped you out!

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!

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!
