Mountain Peak Identifier

Identify the mountains around you with Mountain Peak Identifier. Simply point your phone's camera at a mountain range to instantly see peak names, distances, and elevations overlaid as tappable AR labels in real time. Designed for hikers and outdoor enthusiasts, this app is built offline-first. It requires no accounts and no network connectivity, making it fully functional in remote wilderness areas with zero cellular coverage. 🗻 HOW IT WORKS The app uses your device’s GPS to establish your position and the compass (rotation-vector sensor) to determine your heading. It computes the great-circle distance, bearing, and elevation angle to every cataloged peak, displaying the summits that fall inside your camera's field of view over a live CameraX preview. ⭐ KEY FEATURES • Live AR Overlay: See peak names, altitudes, and distances directly over your camera feed, paired with a top-mounted compass ribbon. • 100% Offline Database: Features a bundled database of 109 world peaks. No internet connection or account creation needed. • Nearby Catalog: View a list of peaks within a 300 km radius, sorted automatically by your current GPS distance, complete with live GPS accuracy tracking. • Global Search: Quickly search the catalog by peak name, mountain range, or country. • Saved Peaks: Save your favorite or visited mountains to a local on-device list persisted securely via Room. • Sensor Calibration: Manually tune compass offsets (-180° to 180°) to correct for hardware magnetic bias. • Peak Details: Access exact coordinates, elevation data, and live-updating distance and bearing from your current fix. 📐 GEOMETRIC ACCURACY & LIMITS Mountain Peak Identifier relies on pure GPS and compass geometry rather than image recognition or terrain-aware models. It calculates what is mathematically within your line of sight. This means a peak will display on screen if it matches your heading and coordinates, even if a physical ridge or cloud cover temporarily hides it from view. ⚙️ DISPLAY & SETTINGS • Toggle easily between metric and imperial units. • Fine-tune the camera field-of-view settings for alignment.
