Ratings and reviews

When I was living in Crested Butte, I LOVED this app. Joel Gratz not only popped in daily w/ accurate data but also explainedhow he was reading the weather models so that subscribers could learn basic meteorology with him. When I moved to Montana this year I figured it was definitely going to be worth it to pay for yet another. The local forecaster must have better things to do w/ his time than spend an hour a day doing the same. I won't repurchase next year.

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.

I used to enjoy this app. Noone I know is continuing with it. Very disappointed in the new model. When first announced, I considered paying, as I don't mind paying a reasonable amount for useful apps. But $30 for an annual subscription. I was shocked. Maybe for lifetime. Even more discouraging is to see all the copy/paste responses that insist this is a small fee for a phone app! They clearly don't live in the same economic reality as us. Thanks to those who recommended OnTheSnow. Switched.
