App Reviews

  • More Stated and More More Mountains

    By SkiandRun
    Then it would be worth the download.
  • So good!

    By Handcuffhonda
    So I never EVER write reviews on apps, but this is what I've been looking for! I love the link to Instagram feature so you can see in pictures what the conditions are like. Weather is THE most important thing to consider when tackling 14ers and this app lays it all out in a really clean and unique way . Love it ! Only suggestion would be to maybe add a "directions to trailhead" section for people who aren't from here.
  • Awesome Mountain Info!

    By AnnaBaldwin
    A great resource for heading out to the mountains! Stoked to use this. Finally some reliable weather forecasts to not get stranded above treeline with lightening. Love the clean design!!
  • Great Start!

    Love that the OpenSnow guys are making an app for hiking. Can't wait to see what they do next!
  • OpenSummit's at the top!

    By Pasrich
    So glad the reliable OpenSnow team developed this app for hikes to Colorado's highest mountains, the 54 14ers. I used this app to plan my backpacking trip to RMNP. Their clear-and-concise hourly forecasts helped me have confidence that I didn't have to start at 0-dark-30 to successfully summit the Longs Peak summit due to storms & lightning. That made my trip a lot more fun! It's a bonus to be able view tagged Instagram photos of the 14ers to get an idea of recent conditions and temperatures (by noticing the type of clothing).
  • Great app- easy to use & accurate!

    By Snocats
    Highly recommend this app- it has helped me stay safe - and choose better weather for my hikes. Super accurate, love seeing the chance of lightening and precip for my favorited mountains.

  • Very accurate ⚡️

    I've been using Open Summit since beta and have found it to be very accurate while hiking my past few 14ers. Missed a storm by 30 min! Nice work weathermen 👊🏻
