Measure altitude with confidence using your device's built-in barometric sensor while monitoring climb performance, elevation changes, and atmospheric pressure in real time. Stay informed with pressure trends, storm awareness, and detailed session tracking built for hiking, trekking, climbing, mountaineering, and paragliding.
Track every adventure with accurate relative altitude readings, live climb rate monitoring, elevation gain statistics, and detailed session recording. Set a custom reference point before you start and measure every ascent relative to your chosen location.
Monitor changing atmospheric pressure through easy-to-read trend charts and weather insights that improve outdoor awareness. Understand how pressure evolves over time with visual graphs, trend summaries, and simplified storm sensitivity guidance.
Record complete sessions with duration, altitude profiles, climb statistics, pressure history, and performance summaries. Review previous adventures through detailed charts and organised history to understand your progress across routes and conditions.
Create and manage multiple reference points for trailheads, campsites, launch sites, summits, or other important locations. Switch between saved references and recalibrate using known elevations for improved accuracy.
Explore an educational pressure guide that explains how atmospheric pressure changes relate to outdoor conditions. Learn how gradual or rapid changes influence the environment through clear visuals and practical guidance.
Use a distraction-free full-screen altitude display with oversized readings for quick visibility during active climbs, in a clean interface designed for excellent readability in challenging environments.
