Prism Environment

Prism transforms your iPhone into every professional measurement and analysis tool you will ever need — with AR visualization that makes the invisible visible. MEASURE MODE — 12 PROFESSIONAL INSTRUMENTS Sound Level Meter with NIOSH-grade accuracy for workplace and environmental noise monitoring. FFT Spectrum Analyzer with waterfall spectrogram for detailed frequency analysis. Vibration Analyzer and seismograph for detecting movement and vibration patterns. Magnetometer and metal detector for locating metals, studs, and wires behind walls. LiDAR distance, area, and volume measurement with centimeter precision on Pro devices. Light meter for photography and workspace illumination assessment. Digital level and inclinometer for precise angle measurement. Speed gun using optical tracking to measure object velocity. Color analyzer that identifies and matches colors from the real world. Barometric altimeter for altitude tracking and weather trend monitoring. Room acoustics analyzer for reverb time and sound quality assessment. GPS compass and tracker for navigation and position recording. EXPLORE MODE — SEE THE INVISIBLE Magnetic field lines rendered in 3D augmented reality. Sound waves propagating visually through your space. Motion trails painted in the air as you move. Environmental heatmaps overlaid on real surfaces. Hidden infrastructure scanner with AR overlay for locating studs and wiring. BUILT FOR ACCURACY Prism uses every sensor on your iPhone — LiDAR, all cameras, accelerometer, gyroscope, magnetometer, barometer, GPS, and microphone. Calibration tools let you fine-tune each instrument. Save measurement sessions with timestamped data. Export readings as CSV for further analysis. Build custom dashboards with the tiles you use most. WHY PRISM? Completely free — no subscriptions, no ads, no in-app purchases. 100% private — all processing happens on your device. Works fully offline. Reference data includes NIOSH sound standards, Pantone and RAL color libraries, and acoustic benchmarks. Replace a toolbox full of expensive instruments with one elegant app. Prism refracts reality into measurable components.
