Reliable, must-have tool

This resource (and the website) is a must-have. All-access is very much worth it alone, but you get OpenSummit subscription with it. I read the snow and weather forecast every day Joel and the others prep. Going to an unfamiliar area, like Colorado->Tahoe? Pull up OpenSnow and realize why their can have rain at the lake and snow on the summits.

Also, their accountability for forecast accuracy stands out. They discuss their prediction vs. reality (retroactively) and it's very informative for understanding mountain weather generally. They will explain when and why their forecasts were wrong -- show me another major weather forecasting website/service that does that! I backcountry ski often, and hike/climb high peaks often in the summer, and OpenSummit's peak-specific forecasts are a crucial tool in assessing mountain weather (along with other resources to confirm, of course). Cross-reference resources.

Best weather app

Top notch daily weather reporting and analysis makes this a must have tool for anyone who needs more info than a sunny/cloudy/snowy icon in a basic weather app. Founding meteorologist Joel provides unmatched weather/snow reporting for the Colorado Rocky Mountains which is the content I access, although there are many other local experts providing snow updates for other regions. I have a snow plow business in the Colorado mountains and this app is my main source for information about incoming weather that will affect our area. If you’re an out of town tourist trying to figure out what our weather will look like during your vacation then use the resource the locals use, welcome to Colorado, and remember to stay in the right lane except to pass!! Thanks again Joel -Scott

Was great, new UI is terrible

This was my favorite app for comparing conditions at resorts to see where I should plan may weekend. But recently they overhauled the interface and it makes it MUCH more difficult to compare snowfall, weather, etc. You used to be able to see this in one easy view, but now you have to slide through individual cards for each mountain, and each card has minimal information (two days of forecast vs five in the old UI, why was this change considered a good idea)

The UI is also inconsistent with the metrics you get in the free tier - in some places you can see 5 days of weather, and in other areas only 2 (further than that is blocked for free users in both cases). I’m fine with freemium, devs need to make money, but make it consistent.

Bring back the single overview of five day snow forecasts of all of your favorites and it’ll drastically improve my opinion of this new version.
