EmberWatch Home

A hyperlocal wildfire risk and evacuation planner for residents in fire-prone regions that combines live satellite hotspots, wind forecasts, vegetation dryness, and your home address into a daily fire-risk score with a ready-to-go evacuation plan.

Target user

homeowners and renters in fire-prone hillsides and wildland-urban interface neighborhoods

Features
  • Personalized daily fire-risk score from 0-100 based on your exact location, wind, humidity, and fuel dryness
  • Pre-built evacuation plan with three route options, a go-bag checklist, and a 'what to grab in 60 seconds' prompt
  • Family check-in tree that automatically texts your group when the score crosses a threshold you set
  • Post-fire damage reporting helper that walks you through insurance photos and forms in the first 48 hours
Why now

Pyrocumulonimbus events are now reaching countries like France that historically didn't have them, and 126-point HN discussion shows growing awareness that 'fire season' is no longer regional.

Demand
7/10

Watch Duty added 600,000 users overnight during the LA fires and reached ~7.2M users, with NYT coverage and a 2021 nonprofit launch — clear evidence of large, acute spike demand that existing apps are already capturing.Watch Duty Wildfire Tracking App Adds 600,000 Users OvernightWatch Duty, a Wildfire-Tracking App, Provides a Lifeline in Los Angeles

Whitespace
4/10

Market is crowded: Watch Duty (7M+ users, free nonprofit), FireSmart Canada (free government app), Augurisk, Frontline, Fires, Zoom Earth, HazardHub, WyldSafe and FireReady Canada all target overlapping needs — the 'daily home risk score + evacuation plan' angle is only modestly differentiated.Watch Duty | Real-Time Disaster Intelligence You Can Trust6 of the Best Wildfire Apps in 2024 - FrontlineTop 10 Must-Know Wildfire Tracking Apps

Monetization
4/10

The dominant player (Watch Duty) is a free nonprofit supported by donations, and FireSmart is government-funded; direct-to-consumer willingness to pay is weak — only niche B2B-adjacent products like SafetyNest or HazardHub show recurring revenue, suggesting monetization is hard.Watch Duty: Nonprofit App Becomes Lifeline During Los Angeles WildfiresPlans & Pricing - Safety NestHazardHub Property Risk Assessment

Longevity
9/10

Climate change is extending and intensifying fire seasons globally, with pyrocumulonimbus now reaching historically non-fire regions like France, and expanding wildland-urban interface — a multi-decade, structural tailwind.Watch Duty Wildfire Tracking App Adds 600,000 Users Overnight

Feasibility
5/10

Core data sources (NASA FIRMS hotspots, NOAA wind/forecast, satellite vegetation indices) are publicly available, but fusing them into a trustworthy per-address daily risk score plus a vetted evacuation plan is non-trivial, and competing with Watch Duty's volunteer firefighter alert network is hard for a small team.Download - FireSmart CanadaFireReady Canada — Prepare your home for wildfire
