The main interface of SMS Commander was similar to that of Any Cut. When you start up SMS Commander, the first thing you have to do is set a four digit pass code. Make sure you write this pass code down somewhere and don't forget it-- once I set my pass code, the app wouldn't let me reset it. Applications similar to SMS Commander sent emails containing the pass code, but since SMS Commander doesn't collect email addresses, there's no way to retrieve your pass code if you ever lose it.
After you have your pass code set, SMS Commander takes you to a dark screen with four commands on it: get location, loud ring, silence, and vibrate. When you hover over any of these commands, SMS Commander gives an explanation of them on the bottom of the page. The explanation SMS Commander gives isn't too great, so I'll explain it here:
When you want to use SMS Commander, you have to start up a new text message. The first thing you need to do is type in your pass code, because without your pass code, SMS Commander will ignore your commands completely. Once you have your pass code typed, select any of the four commands, and press send. You can either send this text message to yourself, or to someone else's phone, provided they have SMS Commander installed, and you have their pass code. When you send 'get location', SMS Commander will send back a text message with your current location. 'Silence' silences your phone, 'vibrate' puts your phone on vibrate, and 'loud ring' raises your ringer-- it's that simple.
