Power Alarm Pro

About Power Alarm Pro Android App

This app is the same as the Power Alarm app but does not display any ads.

Please see the Power Alarm SMS app if you want a version of the app that does not display ads and sends an SMS and/or Email when the power is disconnected or connected.

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. You would need to be within hearing distance for this to be useful. There is a version of the app (Power Alarm SMS) that will send a 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. There is also a free version of the app (Power Alarm) that displays ads.

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 1
Siren 2
None (no sound)
The alarm always vibrates the device.
