Do you know of an app that will take me back to my starting point?

Basically, I’d like to find an app that works like Google Maps or Apple’s Siri but for walking or hiking. I’d like to be able to start the app, then walk, wander, or hike any which way I like; then I’d like to be able to tell it, “Take me back to where I started”. And it can guide me back with voice commands.
