Everything syncs when you're back in range. • Share Conditions — Auto-update park maps, lift status, and trail conditions on your website, social media, or through the Ullr API. ** For Riders ** Follow your favorite mountains to see what's set up in the park, what lifts are spinning, and what trails are open — with push notifications when conditions change.
