OmniTool: Sensor Toolkit

OmniTool brings a practical set of device-based tools into one focused app.

Use the microphone for estimated ambient sound-level readings, check surface tilt with the bubble level, view magnetic-field changes, follow magnetic heading, estimate on-screen lengths after calibration, measure angles, monitor device vibration, and generate reference tones.

Features:

• Estimated ambient sound-level meter with minimum, average and maximum readings
• Two-axis bubble level with zero and hold controls
• Magnetic-field change detector using the device magnetometer
• Magnetic compass heading
• Calibrated on-screen ruler and angle protractor
• Three-axis device-vibration monitor
• 20 Hz to 20 kHz reference-tone generator
• On-device measurement history
• Optional rewarded ad for 24 hours of ad-free use

Measurement results depend on the sensors and calibration of each device. OmniTool is not a certified sound meter, surveying instrument, medical device or safety instrument.
