You know what drives me nuts? When I lose my phone and it is on silent. Sometimes my phone slips out of my pocket and into my couch. One time I spent over an hour trying to find it. The SMS Alarm for Android makes it possible to hear your phone even if it is silent.
You will need to send a text message to your number with a chosen word or number in the body of the text to trigger the app. The app will automatically override the silent setting on the phone and play an alarm. You can also decide how long the alarm will last at up to 2 minutes with an option to have it vibrate.
You can download the app for free on Google Play now. The app was developed by Nebkat.
