Ratings and reviews

OpenSnow is constantly surpassing my expectations. I bought it just to keep tabs on snowfall totals at ski resorts, but every couple months I find out something new that it does that's completely out of the scope of why I originally purchased it (downloadable public land overlay is incredible!). I feel like I bought an app for a specific thing that turns out to do 1000 things I didn't even know I needed. It's incredibly valuable to anyone who likes to adventure outside.

Outstanding weather app (and companion online service). Highly accurate local forecasts, tailored to snowsports and summer mountain activities. They have recently expanded the service to provide world-wide local weather forecasting (with useful hour-by-hour views, precip predictions, etc.). I have been a satisfied subscriber for more than five years -- and it gets better and more useful all the time. It is now my go-to weather app for all purposes.

Too expensive. Replies to other posters say $30 is a small fee but it's not. Other apps charge $1-10 per year or lifetime even. You'd probably make more money charging less because you'd get much higher uptake if it were affordable (e.g 10/100 users * $30 = $300. 50/100 * $10 = $500). Oh well it was a good app while it lasted. I'd also be happy to pay $2/month or so since I don't need the snow forecast in July. Probably change your name though. Free and open software is free.
