Compass: GPS Field & Altimeter Müşteri Hizmetleri

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
