App to find my phone when its on silent

How can I find my phone when it's on silent/vibrate mode?

Sometimes when I can't find my phone, I call it from my wife's phone or my landline. (There's also online service which provides a free call to your phone, it's a handy way to find a missing phone).

Unfortunately, it doesn't work very well if the phone is set to vibrate, and not at all if it's set to silent. Can I configure my phone to ignore the vibrate or silent setting and always ring for a specific number?

My old phone was a Blackberry, and it had a couple of features that made it obvious how to do this: 1) it had very flexible distinctive ring features, 2) it had a feature called "ringer profiles" that allowed users to create additional conditions where special distinctive ring conditions applied. (I mostly used its distinctive ring features to set an annoying person to always silent). Do we have anything similar on Android?

Alternatively, is there another good way to configure the phone to reveal itself even if it's set to silence? (Play music when it receives the word "sing" by text, for example.) If not as a native feature, are there apps that do this?

Finally, I know that nothing will work if the phone is out of charge, turned off, or set to airplane mode. The only solution there is "Don't misplace the phone when it's set to airplane mode."
