Powder Chaser — Stop guessing. Start chasing. Other apps tell you it snowed. We tell you if it's actually good. Our ML-powered snow quality algorithm analyzes 40 data points — from snow compaction and aging to freeze-thaw cycles to wind conditions — to give you a simple answer: is it worth the drive? WHY POWDER CHASER IS DIFFERENT Most ski apps show snowfall numbers. But 10cm of snow means nothing if it fell on an ice layer, got wind-packed, or melted the next day. Powder Chaser tracks what actually matters: • Real snow quality that accounts for compaction, settling, and aging — not just raw snowfall • Quality ratings from Excellent to Not Skiable based on actual surface conditions • ML-predicted scores trained on thousands of real conditions • Multi-elevation analysis at base, mid, and summit 7-DAY SNOW QUALITY FORECAST Plan your powder days with confidence. Our forecast doesn't just show snowfall predictions — it predicts actual snow quality for each day, so you can pick the best day to go. 1040+ RESORTS, 25 COUNTRIES • North America: Whistler, Vail, Jackson Hole, Mammoth, Park City, Aspen + hundreds more • Europe: Chamonix, Zermatt, St. Anton, Verbier, Val d'Isère, Courchevel • Japan: Niseko, Hakuba • Scandinavia, Eastern Europe, Oceania, South America SMART NOTIFICATIONS • Snow alerts when your favorite resorts get dumped on • Thaw-freeze warnings before icy conditions develop • Customizable thresholds — get notified only when it matters BEAUTIFUL MAP VIEW • Color-coded quality pins across all regions • Cluster view showing quality distribution at a glance • Nearby resort carousel with distance and quality • Date selector to preview future snow quality on the map BUILT FOR SKIERS, BY SKIERS • Favorites list for quick access to your go-to resorts • Share conditions with your ski crew • Works offline with smart caching • Metric and imperial units • 13 languages supported Download Powder Chaser and never miss a powder day again.
