Raw Sensor Multitool gives you instant, real-time access to the raw data streaming from your iPhone's built-in sensors — all in one clean dashboard. Designed for DIY makers, engineers, hobbyists, and anyone who wants to know exactly what their phone is measuring. SENSORS INCLUDED • Accelerometer — Live X, Y, Z forces in g. See gravity, tilt, and motion as raw values. Perfect for understanding how your phone moves in space. • Gyroscope — Real-time rotation rates on all three axes in rad/s. Ideal for robotics, motion tracking, and calibration projects. • Magnetometer — Raw magnetic field strength in microteslas (µT) on X, Y, Z. Detect nearby magnets, map field distortions, or calibrate compass-based projects. • Altimeter — Relative altitude change in meters and absolute barometric pressure in hPa. Zero the baseline at any time with the Reset button. • Compass — Magnetic and true heading in degrees, with a live compass rose and accuracy indicator. Instantly see if your magnetometer needs calibration. THREE SENSITIVITY MODES Tap Raw, Balanced, or Smooth at the top of the dashboard to control how data is filtered: • Raw — No filtering. Full precision. Every sensor update displayed as-is. Best for debugging and precision DIY work. • Balanced — Light smoothing with reduced decimal places. Clean and readable. The default mode. • Smooth — Heavy moving-average filter. Dramatically reduces noise. Best for steady observation and general use. DESIGNED FOR DIY PROJECTS Whether you're building a sensor logger, calibrating a magnetometer array, testing a motion-sensitive prototype, or just curious about your phone's hardware — Raw Sensor Multitool puts the data front and center, with no clutter. All sensor data is processed entirely on-device. Nothing is stored, logged, or transmitted.

Verdict
The clearest difference is in-app purchases: SensorsCatalog at none against Sensor Multitool's 3. Sensor Multitool's advantage is device support. On price and iOS requirement there is nothing between them.
