AnyScan209 – Free Professional 3D Ground Scanner & Magnetometer App

AnyScan209 is a completely free Android application that turns your smartphone into a professional 3D ground scanner and magnetic field analyzer. Designed for geophysical surveys, educational experiments, and subsurface anomaly detection, it uses both internal smartphone sensors and external Bluetooth modules (such as HC-05) to provide real-time mapping and visualization of magnetic fields and other measurable parameters.

The app operates in two main modes:

Internal Sensor Mode – uses your phone's built-in magnetometer to record and map local magnetic fields in real time.

External Sensor Mode – receives raw data via Bluetooth (HC-05 and SPP-compatible devices) from various sensors and converts them into visual maps. This allows you to process temperature, altitude, metal detection signals, and any other measurable parameter.

Key features include project management, real-time map plotting during scanning, customizable color gradients, noise reduction, and zoom capabilities. After completing a scan, you can export data in three formats: OBJ (for 3D modeling), STL (for 3D printing), and CSV (for analysis in Excel and MATLAB). The app also supports live data streaming via Bluetooth serial for integration with analytical software.

Getting started is simple: define your grid size (from 8×8 to 100×100 points), enter a project name, and tap the create button. Then navigate to the scan screen and begin data collection. In external sensor mode, tap the Bluetooth icon to find and connect your hardware module. Each received data packet automatically advances the scan by one step.

For advanced users, sample codes are included for connecting microcontrollers like Arduino. If your phone lacks an internal magnetometer, the app automatically switches to external sensor mode. For best results in internal mode, mount your phone on a non-magnetic stand and use a Bluetooth shutter trigger to record points without vibration.

2D and 3D visualization tools allow you to rotate, zoom, adjust depth, and apply smoothing filters to better analyze magnetic variations. Color palettes and amplification modes help highlight subtle anomalies that might otherwise be missed.

Export options include OBJ for 3D modeling software, STL for 3D printing applications, and CSV for data analysis in spreadsheets and scientific tools. You can also stream live data via Bluetooth serial to custom dashboards or Excel macros.

AnyScan209 is an essential and completely free tool for researchers, professors, students, mining engineers, archaeologists, and anyone interested in subsurface exploration.
