A neat feature of Maps on the Apple Watch is the ability to quickly mark your location with a pin, so if (for example) you’re parking your car in an unfamiliar area, you’ll have a simple way to route yourself back to it. To do this, open Maps on your Watch first, and if it’s not showing your current location as the blue dot, tap the arrow at the bottom-left to force it to find you.
Once you’re sure it knows where you are, touch the blue dot. You’ll be taken to a screen with your current address and an option to mark your location.
Tap that, and the familiar iOS pin will appear on the map.
After you’re done getting this all set up, go have your fun. Shop, hike, or do whatever it is you crazy kids do. At any point, you can go back into Maps and tap the pin you dropped to get an estimate for how long it’ll take you to get back to that location, and from that same screen, you can also remove the pin if you so choose.
If you need directions back, just tap either the walking or the driving time estimate, and touch “Start.”
As both a directionally challenged and forgetful person, I love this. Instructions on how to get back to my car right on my wrist, with no third-party app required? Sweet. Now if I just had an app to remind me of where my car keys are or what I walked into the kitchen to do, I’d be all set.
