The Drillers Toolbox, developed by Practica Foundation, is an Android app designed to assist groundwater development tasks. It offers features such as geophysics measurements, drill log data capture and reporting, and pumping tests. The app allows users to organize captured data into projects, and it supports both SI and Imperial units, and is available in English, French, and Portuguese.

The app provides a visual interface for drill log data capture, and after submission, users receive drill logs in a pdf format with professional layout. The app also allows users to capture pumping test data and receive an Excel file with all the data, including drawdown graphs after submission. The app supports Vertical Electrical Soundings (VES) and Horizontal Electrical Profiling (HEP) measurements for geophysics and can be used in combination with the Practica Foundation Volterra device, a low-cost resistivity measurement device. After submission of geophysics data, the user receives a pdf report with the data, computed models for 3, 4, and 5 layers, and an Occam model. The raw data in Excel format is also provided.
