Ariscu Mobile vs LetsGeo

Ariscu Mobile App is a partner app to the Ariscu system which assists users in performing Checklists. You can also quickly create checklists.

Let’sGeo - professional geological field logging app Let’sGeo is a professional offline field tool for geological and geotechnical logging, drilling operations and mineral exploration. Designed for real field and core shed work, it combines geological descriptions, structural measurements, drilling data and geological mapping in a single structured workflow - fully offline. Key features Geological & structural logging • Field points with lithology, mineralization, alteration and weathering • Standardized geological codes with free-text descriptions • Built-in compass and clinometer for dip and dip direction • Structural elements: bedding, joints, faults, shear zones and veins • Vein parameters: thickness, mineralogy and density • Stereonet (Schmidt & Wulff) visualization Geotechnical logging in drillholes • Two-level workflow: - Single structural records linked to depth - Interval-based geotechnical domains • Core recovery, TCR, SCR and RQD • Rock mass parameters and fracture angle classes • Core boxes with depth-linked photo documentation Drilling & sampling • Drillhole runs and recovery tracking • Interval sampling with full metadata • Geological samples linked directly to logging intervals Mapping & GIS • GPS points and drillholes • Coordinate input and conversion (WGS-84, UTM, Gauss-Krüger) • GPS track recording • GPS accuracy recording and storage • Custom point and drillhole marker styles and colors • Point and drillhole visibility controls • Compass-oriented map navigation with live azimuth display • Distance and true bearing (TN) to selected points and drillholes • KMZ layers with map drawing and editing tools • KMZ layer ordering and management • Offline satellite imagery download directly inside the app • Satellite spectral maps for mineral exploration • SWIR lithology, clay alteration and iron oxide composites • Download spectral scenes for offline geological interpretation Reference Collection • Project-based geological reference collections • Rock photos with descriptions and geological notes • Import and export reference collections between projects and devices • Reference image similarity search • Compare field photos with reference collection samples • Find visually similar rock specimens using image analysis of color, grain characteristics, texture patterns and vein features Media & data • Photos, video and audio linked to observations • Field sketch sheets for hand-drawn geological sketches • Photo annotation and markup tools • Offline-first: all data stored locally • Full project export/import • Project Database Archive export • Merge project archives between devices without overwriting existing data wherever possible • Cross-platform data exchange between Android and iOS devices Privacy Let’sGeo stores all data locally on your device.
