Compass Altimeter is a clean, pro‑grade altitude and compass tool that fuses GPS with (iOS) barometer/absolute altitude for faster, more accurate live readings—ideal for hiking, exploration, landscape photography, and stargazing.

Key Features

• Live altitude: GPS + barometric fusion with accuracy readout

• Relative altitude: set a base point to track ascent/descent

• Compass: True/Magnetic North, localized direction text (NESW), subtle haptics

• Calibration & interference: magnetic interference detection with calibration tips

• Sun & Moon: elevation/azimuth, sunrise/sunset and moonrise/moonset

• Photography aide: golden/blue hour with bearings for better framing

• Coordinates: switch between Decimal and DMS; one‑tap copy

• Sources & accuracy: Auto/GPS/Barometric modes; GPS High/Medium/Low accuracy

• Pressure: live pressure with units (hPa/mmHg/inHg/psi)

• Personalization: m/ft, 12/24‑hour, language, precision display, splash animation

Design & Performance

• Large, legible typography with modern UI

• “Fast‑then‑precise” positioning and smart lifecycle for stability and battery savings

Use Cases

• Hiking and outdoor exploration

• Landscape photography timing (golden/blue hour)

• Astronomy and education

• Travel logging and altitude lookup
