Powdaddy ,


The intent of this app is to educate and to hopefully save lives of those who venture out into our beautiful backcountry here in Utah.
I use this app before heading out as
step 1 towards safety and my friends
do as well.&

Fix the app please!

It’s so hard to maneuver this app. While I do like what they tried to do with the update, there are just too many bugs and layout issues. Why do I have to turn my phone sideways to view the app now?

When I try to view event map photos, it doesn’t show you, and when you fiddle with it enough to get the photo to show up it’s incredibly small.

Please update the app and debug! Thank you for all you do!

Kinda works

Everything works well until you click on a zone and then it gives you options to look at. You try clicking on an option nothing happens. Use online versions all the time but doesn’t work on smartphone
