This is a simple app for location and sms services. You can use this app to locate your current location, remember your location, get the direction from your current location to the remembered location, send sms to your contacts for your current location or remembered location.
When you travel to a new place, you can use this app to remember your hotel and guide yourself to your remembered location. You can send out the sms to your contacts about where you are now or you hope them where you want them to meet you.
When you meet some disasters, such as earthquake, flooding..., you could not tell the location you are located, you can send out the message to your contacts about your gps location.
This is the version 1. I am developing version 2 to make the interface more user-friendly.
