WeatherRoute analyzes up to 3 driving routes
between your start and destination, then checks live weather forecasts
at intervals along each route — timed to when you'll actually be there.
It ranks routes by weather safety and highlights hazards.
What do the colored dots on the map mean?
Each dot is a weather checkpoint along your route. ●Green = clear conditions. ●Yellow = moderate weather (rain, reduced visibility). ●Orange = high risk. ●Red = severe — snow, ice, thunderstorms. Tap any dot to see details.
What does the tab bar indicator mean?
After a search, a colored symbol appears under the Details tab. ✓ means your recommended route has no significant weather hazards. ⚠ means hazards were detected — check the Details tab for which route to take.
Why does it sometimes say "weather check failed"?
The free weather API (Tomorrow.io) allows 500
checks per day. Each route search uses ~15–21 checks. When the daily
limit is hit, some checkpoints can't be scored. Results are still shown
with the data that was available.
How do I navigate with this route?
Tap "Open in Apple Maps" or "Open in Google Maps"
on any route card in the Details tab. The app will hand off your origin
and destination to your preferred navigation app for turn-by-turn
directions.
How current is the weather data?
Forecasts come from Tomorrow.io and are updated
hourly. Data is cached on your device for 2 hours to reduce API usage.
For long trips, the further out a waypoint's ETA, the less precise the
forecast.
