- Step 1
Sight the smoke
Aim your phone at the smoke and take a bearing in one tap. True heading, GPS position, and a reference photo are recorded instantly. A bearing line appears on the map.
- Step 2
Cross it, fix it
Move sideways and take a second bearing. The two lines cross, and the intersection is your estimated position—with an honest uncertainty fan, never a fake pinpoint.
- Step 3
Distance and coordinates
Read distance from you, coordinates in decimal or degrees-minutes. Everything is ready to share with emergency services.
- Step 4
See where the smoke drifts
Live wind direction and speed appear on the map. The likely source is marked upwind, as a zone rather than a false pinpoint.
- Step 5
Works fully offline
No fire-data feed required. The bearing fix is measured by your phone's compass and GPS. All data stays on your device—no accounts, no subscriptions, no ads.
- Step 6
Log every fix
Keep a complete record of every observation with photos and position. Review measurements weeks later, replayed on the map with both observation points visible.
