Improved GPS coordinate acquisition for points and drillholes. • Added GPS accuracy display when capturing coordinates • Coordinates can now be refreshed multiple times to achieve better accuracy • Improved handling of weak or unavailable GPS signals • Added clearer status messages when the device cannot provide coordinates • More reliable field coordinate capture workflow

Bug fixes and stability improvements.

What’s New • Minor UI improvements • Small fixes and stability updates

New tools for real fieldwork: — Draw lines directly on photos — Create blank canvas for quick field sketches — Minor improvements and bug fixes

• Various bug fixes and stability improvements • Minor UI refinements and performance optimizations This update improves overall reliability and field performance.

Spectral maps are now available in Let’sGeo. You can download satellite spectral imagery for your project area and view different mineral-sensitive composites directly on the map, including clay alteration, iron oxides and SWIR lithology. This helps geologists quickly analyse alteration patterns and surface mineralisation in the field.

What’s new • Added project-level dropdown lists for geological coding fields (lithology, mineralisation, alteration, weathering, mineralogy where applicable) • Dropdown lists can be enabled per project or switched off to allow free text input • Various minor bug fixes and stability improvements

What’s new • Added a built-in tool for determining the β-angle directly in structural descriptions • Project export now supports Excel (XLSX) in addition to the database file This update improves structural logging workflows and makes project data easier to review and share.

What’s new Expanded geotechnical drillhole logging. • Two-level workflow: single structural records and interval-based domains • Built-in clinometer for core structure orientation (alpha angle) • Structural roughness and JCON76 with visual hints • Core recovery, SCR and RQD • Rock mass strength, alteration, weathering and moisture • Fracture angle classes (0–30 / 31–60 / 61–90°), manual or auto-calculated • Stereonet visualisation of structural data • Linked to core boxes, samples and photos

- Added a Database Viewer for easier inspection and verification of project data - Introduced coordinate conversion tools supporting UTM and Gauss–Krüger (Krassovsky datum) systems - Improved workflows when working with external geodetic and legacy coordinate data - General stability and performance improvements

• Added an offline User Manual guide • Points can now be created by selecting a location directly on the map

What’s new - Added in-app creation and editing of KMZ line and polygon geometries - Improved KMZ layer rendering, labels, and transparency support - Enhanced map drawing tools and interaction precision - Improved GPS track recording and visualization - Bug fixes and general performance improvements

What’s New in This Version This update adds advanced geotechnical and structural geology tools. Geotechnical Measurements Record structural data at points, including dip and dip direction Support for multiple structure types such as joints, faults, veins, bedding, and foliation Additional parameters for veins: thickness, density class, mineralogy, and comments Confidence and surface micro-roughness classification for structural measurements Stereonets Visualization of structural data using geological stereonets Support for both equal-area (Schmidt) and equal-angle (Wulff) projections Display of planes, poles, or both for structural analysis These additions significantly improve the app’s capabilities for structural geology and geotechnical field work.

KMZ geological maps You can now upload your own geological maps using KMZ files. - Import KMZ files with points, lines, polygons and raster layers - Use your own geological maps and field layouts - Edit colors, line widths and styles directly in the app - All data stays in WGS-84, no coordinate conversion required - Works fully offline, ideal for fieldwork This update makes it easy to bring existing geological maps into your projects using a single KMZ file.

What's New - Added full project export with media and structured folders - Export as ZIP including SQLite database and all photos, videos, audio logs and reference collection items - Performance and stability improvements
