Ratings and reviews

Update: the app works great now! Thanks for fixing. We love having accurate, and timely, data. - App does not update regularly. If you uninstall and then reinstall, the data will be accurate. My husband and I both have it on our phones and we do this every couple of days so we can keep up with snotel and not have to lug out our computer

Running android. When I open a snotel site I can't scroll down to see the rest of the data on the graphs and the screen aspect is all wrong. I can't click the favorites button at the top because it is way up in my top bar where the clock battery status etc are. That being said. Thanks to the developer for gathering and distilling this data. Super helpful!

Nice user interface, I like that I can save favorite stations. I wish that it would update more frequently, it appears to me that it reads the daily data (data from midnight, I believe) rather than data for the most recent hour. If it updated hourly I would give this 5 stars. As it is, it's still quite useful and faster than going to the individual Snotel pages for multiple stations.

What’s new

Enabled a subscription model for hourly info, webcams as well as a forecast for the details screen for each snotel site. Various other fixes and features added. Adding experimental weather for fun :)
