Fogline turns the roads you travel into a personal “fog of war” map of the real world. You just live your life — drive and walk — and the phone paints in every road you cover, while everywhere you haven’t been yet stays fogged. There’s nothing to start and nothing to log: it works quietly in the background, and you watch your city fill in.
Fogline is a personal project — free, no subscriptions. It covers Kyiv and the surrounding oblast today, with other regions available as downloadable map packs.

Quickstart

Install, sign in, download your map, and start painting roads.

The map screen

The live map: your position, the roads you’ve painted, and the rest still fogged.

Painting roads

How passive background tracking turns the roads you travel into painted map.

Offline maps

Download a region once and paint it with no signal; add other regions as packs.

Coverage & stats

Your % coverage, the coverage ring, and roads, kilometres and new-this-week stats.

Sync & backup

Your painted map backs up to your account and follows you across devices.

Account & privacy

One free account, what leaves your device (and what never does), and permissions.

FAQ

Coverage, platforms, battery, background tracking, and the honest edges.

The idea in one minute

1

Install it and go about your day

Install Fogline, sign in, and download your region. Then just live your life — there’s nothing to press before a trip and nothing to log after one.
2

Let it paint in the background

As you drive or walk, the phone quietly records where you travel — screen off, app closed. Every road you cover gets snapped to the map and painted in.
3

Watch your city fill in

Open the app to see your live map: painted roads where you’ve been, fog where you haven’t, and your % coverage climbing as the blank spaces close up.
4

It stays yours

Your raw movements never leave your phone — only the set of painted roads backs up to your account, so your map is safe and follows you to a new device.
