App Description
Find your direction. Know your location. Track every journey.
Compass is a precision field instrument for iPhone — combining a real-time compass, GPS positioning, altimeter, barometric pressure monitor, GPS speedometer, and activity recorder in one premium dark-mode app.
REAL-TIME COMPASS
A smooth compass dial that rotates instantly with your iPhone. Shows all 16 cardinal and intercardinal directions with precise 0°–360° degree readings.
• Accuracy within ±5° of true heading
• Smooth needle animation — no lag, no jitter
• Magnetic interference detection with visual warning
• Automatic calibration guide (figure-8 motion)
• VoiceOver support — direction and degrees read aloud
GPS COORDINATES & LOCATION
See exactly where you are. Latitude and longitude in DMS format with a live GPS accuracy reading.
• Coordinates: 105°49′26″ E · 21°1′10″ N
• Live GPS accuracy indicator (e.g., ±6 m)
• Current location name (city/district) with live temperature
• Weather & location refreshed every 10 minutes via WeatherKit
• Cached data shown when offline, with last-updated timestamp
ALTITUDE, PRESSURE & WIND
Three environmental readings always on the compass screen — no tab switching needed.
• Altitude: barometric sensor (GPS fallback if sensor unavailable)
• Atmospheric pressure: displayed in kPa (kilopascals)
• Wind direction: live reading from weather service (e.g., NNW Wind)
FULL SENSOR DATA DASHBOARD
Every sensor reading organized in one scrollable screen. The altitude card stays pinned to the top across 6 sensor groups:
• GPS Coordinates — latitude, longitude, altitude, accuracy radius
• Air Data — temperature, humidity, dew point, wind direction & speed
• Magnetic Field — compass bearing, field strength in μT (microteslas)
• Pressure — barometric pressure, pressure-derived altitude
• Boiling Point — water boiling temperature at current altitude & pressure
• Weather — live conditions, UV index, visibility, from WeatherKit
• Daily Altitude Chart — hourly bar chart with daily max/min elevation markers
ACTIVITY TRACKER & ROUTE RECORDER
Record hikes, runs, bike rides, and walks on a live map. Tracking continues in the background even when your screen is locked.
Activity types: Walking · Running · Mountain Hiking · Cycling
Live stats: elapsed time · total GPS distance · accura
