Know the second the power fails.
Even when you're not there.
OutagePing turns a spare Android phone into a mains-power sensor. If the electricity fails, it sounds the alarm — and with Pro, its cloud texts and calls the people you choose, even if the phone dies.

How it works
Any spare Android phone becomes a power-failure sensor in three steps.
Plug it in
Put a spare Android phone on its charger at the place you want to monitor — home, a relative's apartment, the server closet.
Arm OutagePing
The app watches the charger's power feed — even when the battery sits at 100%. Micro-cuts are filtered out automatically.
Escalating alerts
Power fails → popup, then a loud siren on the phone. With Pro, if nobody stops it, OutagePing's cloud texts your contacts and phone-calls the first one — even if the phone dies.

“Couldn't I just…”
Every alternative assumes someone is there to notice. That's the part that fails.
“My phone will tell me.”
Only if the outage is where you are. Nothing on your phone knows the power just died in an empty house on the other side of the country.
“I'll ask a neighbor to check.”
At 3 a.m., in a dark building, they're asleep too. OutagePing wakes the specific people you chose, the moment it happens.
“My UPS already beeps.”
To an empty room. A beep is only an alert if somebody is standing next to it.
The app wakes the room. Pro reaches people.
A siren only helps if someone is there to hear it.
Texts every contact
Where it happened, when, and how long the power has been out.
Calls the one you choose
A text can be slept through. A ringing phone usually can't.
Emails as backup
Optional per contact, for when a number is unreachable.
Keeps going if the phone dies
Our servers hold their own timer and alert on its behalf.
Includes the web portal — live status, outage history and delivery receipts — and up to 3 monitored phones.
How the dead-man's switch works
Every self-contained gadget has the same flaw: when it dies, it goes quiet — and silence looks exactly like "nothing is wrong". Pro turns that silence into the alarm. Your phone checks in every few minutes; if the check-ins stop mid-blackout — router down, battery flat — our servers alert your contacts on its behalf.
Where people put one
Anywhere a power cut quietly costs you something.
Freezer & food
A dark fridge for six hours ruins hundreds in groceries — and you'd never know.
An elderly parent's home
Their power fails, your phone rings. You call, you drive over, you fix it.
Aquarium & pets
Pumps, heaters and filters stop silently. Minutes matter.
Shops & server closets
Know before the UPS runs out, not after the outage report.

Billed from day one · cancel anytime · keep the free app
Pro includes up to 60 SMS + 20 call-minutes per month — far more than a normal home ever needs. Requires Android 8.0+ and a phone kept on its charger. For alerts during a full blackout we recommend a SIM with mobile data (see docs). Prices include VAT where applicable · 14-day refund policy.
Questions, answered
Does it still detect the outage when the battery is already at 100%?
Yes — that's the core of the design. OutagePing watches whether the charger is supplying power, not whether the battery is charging. When mains power dies, the charger's voltage disappears instantly, and OutagePing reacts — even at 100%.
What if my Wi-Fi router dies in the blackout too?
The local alarm always works. For cloud SMS/calls, we recommend a SIM with mobile data in the monitoring phone — cell towers have backup power. And Pro's dead-man's switch alerts your contacts even if the phone can't reach us at all.
Can I stop a false alarm?
Yes. The first stage is a quiet popup with a STOP button and a configurable delay before anything loud or external happens. Unplugged the phone on purpose? One tap and nothing else fires.
Why is the app free but Pro paid?
The app itself — power-failure detection and the on-phone alarm — is free forever. Pro covers the ongoing cloud and carrier costs of texting, calling and emailing your contacts every month, plus the dead-man's switch that works even if the phone dies.
Is this a certified safety system?
No. OutagePing is a consumer alerting aid and shouldn't be the only safeguard for life-critical equipment. It's the difference between finding out in minutes and finding out too late — but please keep professional systems where lives depend on it.
