G-TOOLS

G-TOOLS: Your Complete Mobile Toolkit for Precision Measurement and Calibration

G-TOOLS transforms your Android device into a professional-grade measurement and calibration station. No separate hardware, no bulky instruments—just your phone and a suite of scientifically validated sensors. Whether you need to check surface levelness, measure magnetic fields, or calibrate a digital scale, G-TOOLS delivers laboratory-accurate readings in seconds.

Core Functionality
The app activates your device's built-in hardware sensors to perform real-world measurements. The Digital Level uses the accelerometer and gyroscope to measure tilt angles with 0.1° precision, displaying both numeric values and visual bubble-level indicators. The Magnetic Field Sensor (magnetometer) detects electromagnetic interference and measures field strength in microteslas (µT) with a live graph showing fluctuations over time. The Sound Level Meter captures ambient noise via the microphone, displaying decibel (dB) readings with A-weighting filter for human-hearing accuracy. Each tool operates independently or simultaneously in multi-panel mode, allowing you to monitor four parameters on one screen.

Key Advantages for Daily Use
- Real-time calibration: Every measurement tool includes a zero-set button to eliminate sensor drift, ensuring consistent accuracy across sessions.
- Data export: Save measurement logs as CSV files for professional reporting or share them via email directly from the app.
- Low-light interface: A dedicated dark mode reduces battery drain during extended use, with high-contrast readouts visible in direct sunlight.
- No ads in measurement mode: The interface remains completely clean during active readings—ad banners appear only in the settings panel.

Essential Features
- Digital level with audible tilt alert (customizable threshold from 0.5° to 45°)
- Magnetic field detector with peak hold and frequency analysis
- Sound level meter with max/min/average recording over user-defined intervals
- Altimeter using barometric pressure sensor (relative altitude accuracy ±1 meter)
- Compass with true north and magnetic north toggle, plus declination adjustment

This app requires internet connection for initial sensor calibration data download and optional cloud backup. In-app purchases available for extended data logging (unlimited CSV exports) and advanced calibration profiles. Continued use of GPS and background location services may decrease battery life.
