A weather planning app for drone pilots. OpenDroneWeather fetches a 16-day hourly forecast for any location and scores every hour against your drone's flight limits — so you can see at a glance when it's safe to fly.
- Flight score calendar — a 3-week grid where each day shows colour-coded hourly scores in a single column, giving an instant overview of the week ahead
- Hour-by-hour detail — tap any day to scrub through a full time strip showing wind at 3 altitudes, gusts, temperature, humidity, cloud cover, visibility, and a score breakdown
- Drone profiles — built-in presets for popular DJI models, plus full support for creating and editing custom profiles with your drone's exact operating limits
- Smart scoring — hard blockers (rain, excess wind, temperature extremes) immediately zero out a score; remaining hours are ranked by a weighted multi-factor model
- Sun & golden hour — sunrise, sunset, dawn, dusk, and golden-hour windows are overlaid on the day detail view
- Night flying toggle — optionally restrict scores to daylight hours only
- Flexible units — wind in km/h, m/s, or mph; temperature in °C or °F; distance in km or mi
- Offline support — forecasts are cached locally so previously loaded data is available without a network connection
