Your city hides beneath a blanket of fog. Walk around to clear 100m grid cells, uncover hidden rewards, and watch your personal map come alive with every step you take.
How It Works
No setup needed. Just open Breevy, start walking, and let the map reveal itself beneath your feet.
Your city appears covered in fog. Each 100m × 100m cell is a mystery waiting to be revealed by your footsteps.
Background GPS tracking automatically detects when you enter a new cell. No tapping required, just walk naturally.
As you walk through each cell, the fog lifts and the real map appears underneath. Watch your coverage grow in real time.
Hidden in unexplored cells are bonus XP drops, exclusive badges, and surprise rewards. Every walk could uncover something special.
Feature Highlights
Fog of War turns every walk into a game. Whether you are commuting, jogging, or just wandering, your map grows with you.
The city is divided into a precise 100m × 100m grid. Each cell you walk through is permanently revealed on your map, giving you granular control over your exploration progress.
Breevy tracks your location silently in the background. No need to keep the app open. Your explored cells are recorded automatically while you go about your day.
See exactly what percentage of your city you have explored. Track your progress over time and set personal goals to reach new coverage milestones.
Turn everyday walks into exploration. Take a different route to work, explore a new side street, or detour through a park. Every step counts toward your coverage.
Scattered across unexplored areas are secret reward cells. Walk into one to unlock bonus XP, rare badges, or surprise drops that you cannot earn any other way.
Your fog map is a living record of everywhere you have walked. Over days, weeks, and months, watch the fog dissolve and your personal city map take shape.
Rewards
The more fog you clear, the more you earn. Hidden rewards, milestone badges, and XP bonuses are waiting beneath the fog.
Random cells contain XP bonuses ranging from 25 to 500 XP. Walk into one and watch your level jump.
Earn badges at 10%, 25%, 50%, 75%, and 100% city coverage. Each tier unlocks an exclusive explorer badge.
Reveal cells on consecutive days to build a streak. The longer your streak, the higher your XP multiplier for each new cell.
Some fog cells hide undiscovered gems. Clear the fog and a new hidden gem appears on your map, exclusive to fog explorers.
Supported Cities
Each city has its own bounding box and fog grid. Track your coverage independently and compete to fully reveal every city you visit.
