Compass Altimeter: Sun & Moon

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

Privacy & Permissions • Location while in use only; used for altitude and sun/moon calculations (no continuous background tracking) • Motion/Barometer (iOS) improves altitude accuracy • Preferences stored on device; no personal data uploaded

Disclaimer • Measurements depend on environment/device and are for reference only • Not for aviation, medical, or life‑critical use
