Ping!

Ping! gets your friends attention even when their phone is on silent mode.

Ping! is an app that lets you send either a long vibration or a loud alarm instantly to someone important to you. It doesn't matter if your friend's phone is on silent mode, they will hear you because Ping! will make their phone beep loudly or vibrate for a long time or until they stop it. Also, the screen will turn on to attract your contact's attention.

If their phone is off or has no signal, it'll get the urgent alarm as soon as it's back on.

You only need to create a user account and send a request to a friend. Once they accept it, both of you'll be able to send each other short messages along with a long vibration or a loud alarm.

Enjoy this easy-to-use and completely free application and don't let silent mode make anyone miss an emergency!
