BackcountrySOS

This app needs cell service to send a text message to emergency responders. Something to be aware of when deciding to make this app /your phone - your sole emergency signaling device

Good idea. Android version could use some polishing: the "Next" button to is halfway off the bottom of the screen, so it's hard to use with cold hands/gloves, especially since it's right next to this phone's "home" button. Critical buttons should be centered enough to push them with a nose and not worry about hitting off-screen buttons (commonly near the bottom). Also, if Location services are turned off when launching the app please prompt the user to turn them on, like Google Maps does.
