Game changer for my morning runs. I used to waste 20 minutes checking different weather apps. Now I just open Run Window and go.

Living in Seattle, finding dry running windows is crucial. This app actually understands that 'light rain' is fine for us PNW runners.

The heat index awareness is perfect. It learned that I hate humidity and now warns me before Texas summers get brutal.

5 AM running is non-negotiable here in summer. Run Window helps me find those precious cool windows before the sun takes over.

Wind chill calculations are spot on. No more getting caught underdressed on the lakefront trail. My wife thinks I've become a weather psychic.
