GoWindow

Pick a sport. GoWindow scores the next three days hour by hour and tells you when to head out. Free includes best-window alerts. Pro adds more places and alert controls.

GoWindow scores the next three days of outdoor weather, hour by hour, and tells you when to head out.

Pick a sport. Running scores apparent temperature, dew point, and UV. Cycling scores wind, gusts, and road wetness from recent rain. Hiking scores thunderstorm timing, daylight hours, and trail wetness. The same afternoon can be good for a ride and rough for a run.

Set the window length per sport: 1, 2, 3, or 4 hours. Tap any hour to see what's helping or hurting the score.

You can change units anytime; GoWindow keeps the underlying values consistent. Switch between °C/°F, km/h/mph, and mm/in in Preferences.

Weather forecasts come from Apple WeatherKit, fetched on-device. Air quality (AQI) requires a network lookup. No account or sign-in required.

Free includes one sport and one saved place. Best-window alerts fire only for Excellent conditions and pause for 7 days after each alert.

Pro includes all three sports, up to 10 saved places, configurable alerts for up to three places without the Free cooldown, multi-sport widgets, and the per-hour factor breakdown. Monthly and annual plans are available; the annual plan includes a 7-day free trial.

iPhone only. iOS 17 or later.
