Pocket Lab: Sensor Toolbox

Pocket Lab turns the sensors already in your iPhone into a set of precise, easy-to-read instruments. Every tool has a clear live readout, a graph, and one-tap recording, and everything runs on your device. TOOLS • Magnetometer: magnetic field strength in µT with ring, LED bar, radar and graph views. • Bluetooth Scanner: nearby devices and their signal strength. • Vibration Meter: 3-axis acceleration and a 40-band frequency spectrum. • Barometer: air pressure and relative altitude. • Light Meter: front and back illuminance in lux. • Audio Recorder: waveform and spectrum, voice-band filter, reverse playback and on-device transcription. • Tone & Noise Generator: white, pink, brown, blue and violet noise, test tones from 20 Hz to 20 kHz, and sweeps. • Pose Tracking: body, hand, face, dog and cat tracking with several engines, up to 4K and 240 fps. • Depth Camera and 3D Scan Viewer: LiDAR and TrueDepth depth maps, point clouds and USDZ/PLY export. • Pose + Depth: pose tracking placed in 3D space. • Multi-Meter: several sensors on one screen, recorded together. • Sessions: review, play back and export everything you record (CSV, JSON, audio, video, 3D). DESIGNED FOR iOS Liquid Glass design with System, Light and Dark appearance, six Home layouts, Siri and Shortcuts, and translations in 13 languages. PRIVATE BY DESIGN No account, no ads, no tracking. Your data stays on your device until you export it. Readings come from your device's built-in sensors and can vary by model and environment. Pocket Lab is not a certified measuring instrument. Pocket Lab Pro unlocks the depth tools, Pose + Depth, the full Multi-Meter, recording and export. Subscriptions renew automatically unless canceled at least 24 hours before the end of the period.
