. 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)

Version History Improved altitude accuracy. Barometric altitude is now calibrated only from a stable GPS fix, so a weak first signal no longer throws the reading off. Until calibration completes, the app asks you to step outdoors instead of showing an unreliable estimate. Also includes reliability improvements. 1.5.2 Sep 29 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. 1.5.1 Jul 30 New in 1.5.0
• Tap the altitude to open Altitude details: effective oxygen, water boiling point, sea-level pressure, air density, and a 3-hour pressure trend chart.
• Optionally show effective oxygen right below the altitude reading.
• Fixed overlapping elements in landscape; cleaner layout.
• Faster, more reliable altitude and location, with better recovery after errors. 1.5.0 Jun 29 What's new in 1.4.1
• Steadier altitude readings.
• New: choose coordinate system (WGS84 / GCJ-02) to match China maps.
• Clearer icons in red night mode.
• Home-screen widget altitude & time now follow your app settings.
• Stability improvements and fixes. 1.4.1 Jun 24 What's new in 1.4.0
• More accurate altitude readings on Android.
• More accurate Sun & Moon times, positions, and golden/blue hour.
• AR sky now aligns with your phone's real camera view.
• Smoother on phones without a compass or barometer, with clearer guidance.
• More honest altitude accuracy, with a warning when it may have drifted.
• Refined, less obtrusive photo check-in watermark.
• Reorganized settings, plus fixes and polish. 1.4.0 Jun 20 Version 1.3.0
• AR Live Sky — raise your phone to the sky to see the sun and moon paths, and find the Milky Way in augmented reality.
• Time Machine — scrub through time to preview the sun/moon position at any moment.
• Red Night Mode — a red-light display that protects your dark-adapted night vision while stargazing.
• Home Screen Widgets — golden hour, blue hour, moon phase and altitude at a glance.
• Altitude Check-In — capture a photo with an altitude and location watermark to log your summit.
• 15 new languages and a refreshed look throughout. 1.3.0 Jun 19 This update focuses on real-device altitude and compass reliability:
• Improved altitude accuracy handling with clearer barometric precision states
• Added localized wording for uncalibrated altitude precision
• The compass now pauses while the camera is open to avoid background sensor activity and haptic feedback
• Improved startup and settings resilience for saved measurement preferences
• General stability improvements for outdoor use 1.2.2 May 26 This update introduces a major new feature: the Altitude Camera.
You can now take photos during hiking, trekking, or cycling with accurate altitude and coordinate watermarks, making every shared moment more meaningful.
We’ve also refined the visual details across all forecast pages, giving the altitude tools a true premium look and feel. 1.2.1 Jan 21 This update introduces a major new feature: the Altitude Camera.
