I have been using this app for a while, and its not inaccurate, its just terrible at updating. I use to work at a ski hill, and we had a 30cm pow day, and the hills website said 30 cms from 6:00 in the morning. It took 5 if not 6 hours for the app to even alert me that there had been snow, and by then it was mostly skied off. Dont know whose at fault here but that kinda put me off of this app, not the first time its happened either. Hope to see some improvement.
