LiveHeight

LiveHeight turns your iPhone's built-in barometer into a precision altimeter that reveals altitude changes as small as a few centimeters, live, on a clean dashboard with a real-time sparkline.

PRECISION ALTITUDE
• Live altitude from the iPhone's barometric sensor
• Altitude above sea level, fused from GPS and the barometer
• Real-time sparkline to watch every rise and fall
• Metric or imperial units

STORM WATCH (works offline)
• Tracks atmospheric pressure trends to warn you before storms roll in
• No signal needed, built for the backcountry
• Optional background monitoring, off by default and fully under your control

BUILT FOR HIKING
• Track a hike and save it to Apple Health as a workout
• Topographic maps and 3D terrain views
• Elevation profiles and terrain lookups for the trail ahead
• Hike prep cards with the essentials before you set off
• Outdoor conversion tool for multiple occasions
• Sunset times so you know how much daylight is left
• Emergency mode: continuous location tracking, then a power-saving standby that keeps your position findable for days
so rescuers can reach you

PRIVATE BY DESIGN
• No account, no ads, no tracking
