. Feature attribute lookup: Tap directly on the screen to query map feature attributes.
. Layer comparison: Smoothly compare data layers using an intuitive opacity slider.
. Multi-format support: Easily open and view GPX, KML, and GeoJSON files.
OFFLINE MAPS
. MBTiles support: Download offline maps in MBTiles format for seamless navigation without internet.
. Tile data sharing: Share map tiles with colleagues to save bandwidth during field surveys or offshore maritime operations.
TRACK LOGGING & WAYPOINTS
. Real-time tracking: Continuously record your movement paths in real time.
. Waypoint marking: Mark reference points with high-precision GPS coordinates.
. Flexible data export: Export collected data to GPX (compatible with Google Earth, Garmin) and DXF (for AutoCAD and GIS).
GEOTAGGED CAMERA
. EXIF metadata tagging: Capture photos with automatically embedded GPS coordinates.
. Customizable metadata: Add custom titles and descriptions saved directly inside the image file.
. Map-based photo view: Visualize and display photos based on their geographic locations on the map.

Version History BUG FIXES
• Fixed a crash affecting a small subset of users when importing large GPX tracks.
• Fixed an issue where background GPS recording intermittently stopped after receiving a phone call.
• Resolved an intermittent UI freeze when switching between map layers.

OTHER
• Updated server endpoint hostnames in configuration (no user action required). 1.4.15 Sep 6 Bug fixes and stability improvements.

• Fixed a crash that occurred when opening GPX, KML, or GeoJSON files
shared from the Files app or iCloud Drive.
• Fixed a crash in the Photos view when saving photos to Camera Roll. 1.4.14 May 31 IMPROVEMENTS
• Faster app launch: server settings now load asynchronously in the background, eliminating the startup freeze.
• Full support for iPhone 14 and later with Dynamic Island: toolbar buttons and ad banners are now correctly positioned clear of the Dynamic Island and the Home Indicator on all device sizes.

BUG FIXES
• Fixed a crash that occurred when opening a corrupted or malformed GPX file shared from another app.
• Fixed a crash when loading GeoTagged photos with missing or invalid GPS metadata.
• Fixed a crash when the GeoServer returned a non-standard JSON response for layer lists.
• Fixed an issue where alert dialogs were hidden behind the map view on certain screen sizes.
• Fixed Pro/Unlimited users occasionally still seeing ad banners after purchase — banners now disappear immediately upon successful purchase.
• Fixed the crosshair marker not appearing when adding a new waypoint after toggling off the Ruler Bar or Map-Center Coordinate overlay.
• Fixed banner ad placement being partially obscured by the system Home Indicator on iPhone Plus and Max models. 1.4.13 May 25 Version 1.4.12

• Background GPS recording now keeps tracking reliably while the screen is off or the app is in the background.
• Fixed an issue where the map view could cover dialogs before you had a chance to tap OK or Cancel.
• Fixed crashes when opening corrupted or missing GPX files, photos and GeoServer responses.
• Faster cold start — remote configuration is now loaded asynchronously instead of blocking the launch screen.
• "Add marker from map": the center crosshair is always visible while you align, regardless of your Ruler Bar setting.
• iPhone 14 Pro / 15 Pro / 16 Pro / 17 Pro: ruler bar and AdMob banner now respect Dynamic Island and the home indicator.
• AdMob banner repositioned to the safe area to comply with the latest ad placement policy.
• Pro / Unlimited subscribers no longer see banner ads on any screen.
• DXF export no longer crashes if the disk is full — you'll see a clear error message instead.
• Updated official website to https://gtfield.rbc.vn (Help, About, Terms of Use, Privacy).
• Updated location, motion and tracking permission descriptions to comply with the latest App Store guidelines.
• Refreshed Google Maps, Google Places, Firebase and Google Mobile Ads SDKs.
