  • Good data for the sites you can find

    By rgr195v1
    As a rock climbing planning app it’s pretty limited. There are major crags and climbing areas that you can’t find. You would think something like red river gorge or new river gorge would be easy to get weather data on….
  • Subscription

    By Buzios 1986
    I bought the Subscription thinking that I was going to get 10 days forecast but my app shows only 5 days
  • Great app

    By haydenglines
    I religiously use OpenSnow and OpenSummit before any adventure (and even when I masochistically decide to check the weather while I’m stuck at my desk). They’re always coming out with new and inventive features, improving their forecasts, and app experience. These are must have apps for any outdoor sport or weather nerd.
  • I was wrong

    Missed the tab
  • So helpful!

    By Bbensch09
    I live in tahoe and have used the smoke / air quality forecasts every day the last two summers when the fire season heated up. Love all the work the OpenSummit/OpenSnow has made happen!
  • Smoke (surface)

    By prgregory
    Very disappointed in your map that details smoke on the surface. Very low visibility and terrible air quality here in Santa Fe New Mexico. But your map shows nothing amiss. Today the density of smoke is much greater than normal although every day for weeks we’ve had smoke in the air and reduced visibility of our mountains. Just wanted you to know that I tried hello@open couldn’t get that to open up no matter how many different ways I tried. Weather channels app also shows perfectly clear air here. Boggling my mind. at least their website provide you with a very easy way to give feedback.
  • Saved my summer road trips from ruin

    By Kav, MD
    The mountain weather is now so much more complicated in the West with fires and smoke. This app brings everything together and lets you plan your missions with remarkable insight. For the last 3 summers, my road trips across the US would have been nightmares without this valuable info. What a great bargain, too.
  • Doesn’t do much unless you subscribe

    By MommyinTruckee
    It do doesn’t give you info unless you subscribe.
  • Unmatched forecasting

    By EMunkW
    I live on a large lake in northern Utah that seems to make it difficult to predict weather forecasts. Open Summit is the only source I use now to view upcoming storms and get reliable weather predictions. I really love the smoke (surface) overlay, and air quality forecast in summer months in order to plan for days that my children should play indoors. I love this app and am constantly sharing screenshots of maps to family and friends. Well worth the $20 annual fee.
  • Phenomenal App
