Watcher lets your friends and family virtually watch out for you. It’s a simple way to be a little more safe when you’re out alone after dark.
It works like this: You enter your destination and choose one or more contacts ('watchers') to oversee your trip. If you start running, stray off course, stop for too long, or get your headphones yanked out, Watcher will ask if you are alright. If you do not respond within 30 seconds, your watcher(s) will be notified and asked to contact you.
