Questions people ask
Everything worth knowing before your next walk.
What is Fog of Dog?
Fog of Dog is a dog walking app that turns your neighborhood into a fog-of-war map. Every street starts hidden under fog. When you walk somewhere, the fog clears around your route and stays cleared, so your map fills in over weeks and months of ordinary walks.
Is there an app that shows me which streets I've already walked?
That is exactly what Fog of Dog does. It keeps a permanent record of everywhere you have walked, drawn directly onto a real map — cleared areas stay revealed, and everything you have never visited stays under fog.
Do I have to do anything while I'm walking?
No. Start a walk and put your phone away. Fog of Dog tracks your route in the background with the screen off and the phone in your pocket, and clears the fog as you go.
How do I explore more of my neighborhood?
The app nudges you toward nearby streets you have not walked yet, so there is always somewhere new within a block or two. Most people find they have been repeating the same three routes for years.
Is Fog of Dog available on Android?
Yes. Fog of Dog is available on Google Play for Android and on the App Store for iPhone.
How much does Fog of Dog cost?
It is a one-time purchase of $4.99. There is no subscription, no advertising, and no in-app purchases.
Is my location data private?
Yes. Your location history and explored map stay on your device. There are no accounts, no ads, and no advertising trackers.
Do I need a dog to use it?
No. Fog of Dog works for any walking, running or cycling — the dog is optional, though the app is built around the rhythm of a daily walk.
Will it drain my battery?
You can choose between Balanced, High Accuracy and Battery Saver tracking modes, so you can trade GPS precision against battery life on longer walks.
