About this app

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 ------------------------------------------------------- Compass Altimeter Subscription Service Introduction: 【Premium Membership Features】 - Red light eye protection display for night use - Display measurement precision information - Display environmental magnetic field data in real-time - New restricted features to be added in the future Subscription Options: - Monthly: $1.99/month - Yearly: $9.99/month (billed annually) - Lifetime: one-time purchase $19.99 - Payment: Once the user confirms the purchase, the charge will be made to the iTunes account. - Cancellation: To cancel the subscription, please manually turn off auto-renewal at least 24 hours before the current subscription period ends in 【Settings】 → 【Apple ID, iCloud, iTunes & App Store】 → 【Subscriptions】. - Renewal: The iTunes account will be charged within 24 hours before expiration.

Compass readings are now more stable when you rotate or tilt your device. Barometric altitude that has not yet been calibrated by GPS is clearly marked as an estimate, so you can interpret the measurement with confidence. For the most accurate altitude, keep Location Services enabled and spend a moment outdoors with a clear view of the sky; calibration completes automatically when the GPS signal is good enough. We also refined sensor handling and overall reliability for smoother readings during hiking, travel, and everyday outdoor use.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
