SnowTopo

SnowTopo is an offline trail map app for skiers and snowboarders.

Core features: • Offline vector trail maps for major ski resorts — no cell signal required • Live GPS positioning — see exactly where you are on the mountain • Slope-angle color overlay — spot steep terrain at a glance • Tap any trail for details — name, difficulty, and status • Pinch-to-zoom and pan across the full resort map • Favorites and recently viewed resorts — get back to your go-to spots in one tap • Share your live location with friends so you never lose each other on the mountain • Record your ski sessions — GPS track, distance, vertical drop, and speed for every run • A dedicated stats page to review your day on the mountain

SnowTopo works entirely offline. No signal in the backcountry, no problem — every feature works the same whether you're at the base lodge or deep in a valley with zero bars.
