Ever kept your phone on 'silent' mode and kept it somewhere you can't remember?
If your answer is yes, Ring My Droid is the app to solve your problems!
Ring My Droid application has an SMS-triggered alarm system. When you install the app, you are asked to set a 'Key Phrase'. Then at any time after that you ever forget where you kept your phone, just use another phone or get on of your friends to SMS your Key Phrase to your phone.
Once the phone receives the Key Phrase as a SMS message, it starts to ring even if it is kept of silent mode! After the it is just a matter of following the sound and finding your phone back.
By default the Key Phrase is set to RingMyDroid. Change it to whatever you want and click the 'Set' button. It is highly recommended that you set a new Key Phrase.
Your Key Phrase is like your password. Keep it with you, otherwise people or some prankster friends may SMS you your Key Phrase and set off your alarm anytime! ;)
