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 · accurate distance (high-confidence GPS) · average speed · max speed · temperature
Map styles: Standard · Dark mode · Satellite — switch anytime during recording.
GPS PHOTO — LOCATION-STAMPED IMAGES
Take or select a photo and Compass automatically attaches your GPS coordinates and altitude to it — a permanent, precise location record. Perfect for field workers, surveyors, hikers, and photographers.
GPS SPEEDOMETER
Precision analog speedometer (0–240 km/h) powered entirely by GPS. Opens and starts measuring instantly — no buttons, no setup.
Tracks: current speed · max speed · average speed · total distance · accurate distance · altitude · heading
