Power Alarm SMS
If you don't want to send a SMS and/or Email, please select the Power Alarm Pro app.
Power Alarm is an anti-theft application for Android devices (phones and tablets). It provides a special level of security when charging your phone in public places (airport, hospital, office, etc.). When the alarm is activated, if your Android device is unplugged from its power source, Power Alarm vibrates and sounds an alarm. The app can also be used to notify you of a power outage. The app will optionally send a SMS text message and/or email when power is disconnected and connected. The app can also be used to notify you (short sound) that the device has become fully charged.
Features:
Power Alarm has two alarm states:Enabled (red)
- removal of power sounds the alarm.Disabled (green)
- removal of power does not sound the alarm.
Power Alarm has two battery charge notification states:Enabled (red)
- when fully charged, a short sound is produced.Disabled (green)
- when fully charged, no notification is produced.
The Power Alarm app does not have to be running for the alarm to sound. The alarm will sound even if the Android device is sleeping (screen is off). While sleeping, when the alarm is tripped (power removed), the device will wake up and display the unlock screen. Having an unlock password provides an added level of security.
The app displays power connection state (connected or disconnected). The state displays if the device is connected to a computer (USB) or wall outlet (AC). Many Android devices charge at reduced rate (1/2 amp) if connected to a USB source and at a faster rate (2 amps) when connected to AC (wall plug).
When the alarm is tripped, the Power Alarm app is shown automatically (after unlock) and displays the 'Silence' button. If you have set a password (in the settings), it must be entered correctly for the alarm to silence. While the alarm is sounding, the device's sound volume is set at max and cannot be lowered or muted. When the alarm ends, the original volume is restored.
While the alarm is sounding, reconnecting power stops the alarm (most likely action by a thief after unsuccessfully trying to lower the volume). The alarm can be enabled while power is not connected and the alarm will not sound (until power is connected and then disconnected). The alarm's enabled state is maintained even if the device is powered off (and rebooted). After reboot, if the alarm was previously activated and power is not connected, the alarm will sound. Note: some phones and versions of Android do not automatically sound the alarm unless power is connected and then disconnected after reboot.
The alarm can optionally (highly suggested) have a password set so silencing the alarm requires the entry of the password. This password is in addition to the wake up unlock password if present. The alarm has a sound start delay setting where after the phone vibrates the alarm does not sound for the specified delay setting. If you forgot that the alarm is enabled, this enables you to re-connect power and stop the alarm from sounding.
The alarm has a duration setting after which the alarm ends without any other action. Other than the sound nuisance, stopping the alarm saves from the battery being drained.
There are 4 alarm sounds:Voice (a human voice saying "Power Alarm" repetitively)Siren 1Siren 2None (no sound)The alarm always vibrates the device.
When the alarm is active, an indicator is displayed in the notification at the top of the screen. You will find this feature helpful to remind you that the alarm is active and not trip the alarm yourself. The notification feature can be turned off to provide additional stealthiness.
You can adjust the percent battery charge that triggers the charge complete notification. Note that many phones do not charge to 100%.

Exactly what we needed. We live in a RV Park and have a refrig in our shed, which has experienced power interruptions (tripped breaker). When we travel, this app emails us of any interruption, using the Park's WiFi system which isn't affected by our tripped breaker. We can then contact a friend to reset the breaker. A nice addition would be if the app could periodically let us know it was still working.
Seems like when the power is out and you're not on a cell network then the email alerts are useless. While the power is out the wifi is down and it fails to send. Then when when power is restored it doesn't re-try to get out a successful email when the wifi network returns so you never know that the power was out unless you use a cell phone on a cell network.
Great tool, however would like to have multiple receipients for sms, and I not comfortable giving this app my Google password!
This app is great!!!! I have been looking for this for a long time
If volume is off, then the alarm will not sound. I've got a galaxy tab.
I've been having issues with a circuit breaker. I connected an old phone to it and installed this app. It has reliably notified me via WiFi (on a different circuit) when the breaker trips and when I turn it back on. The only thing I would like to see added is the ability to ping it remotely, but I know that's much easier said than done.
