Gauges is a comprehensive utility app that utilizes your device's built-in sensors to provide real-time measurements. It includes functions like a GPS, altimeter, speedometer, barometer, accelerometer, magnetometer, sound level meter, and light meter. The app displays this data through real-time graphs and can show your location and heading on a map.
Key features include real-time readings from multiple sensors, speed displayed in various units (kph, mph, knots), GPS and pressure altitude, barometric information, accelerometer readings (G forces), location and heading, magnetic force measurement, sound level in dB, and luminance. It also offers data recording, value marking, and sharing capabilities.
The app is free to download and use with its core functionalities. However, certain advanced features, such as recording all data for spreadsheet export, viewing all sensor information at once, setting data update frequency, and enabling/disabling individual instruments, require an in-app purchase.
The magnetometer in Gauges can be used for various practical applications. For instance, it can help you find hidden cameras, detect metal structures, or even identify electric wires behind walls. This feature allows you to explore the magnetic field around you.
Yes, you can record sensor data with Gauges. For the ability to record all data and share it with other apps in CSV format, an in-app purchase is required. This allows you to analyze your sensor readings in detail on a spreadsheet or other compatible applications.
