SoundMeter X turns your iPhone or iPad into a handheld data-logging sound level meter (SLM), data-logging noise dosimeter, stereo signal generator, multi-channel data recorder, and real-time whole or 1/3 octave band spectrum analyzer (subscription or perpetual license required for most features--14-day free trial available). Input signals can be acquired from any available audio input path. Sensitivity calibration can also be performed for any audio input device and/or input channel. Direct hardware support (automatic sensitivity calibration, based on factory-defined values) for The Modal Shop’s 2-channel 485B39 USB-ICP interface and miniDSP’s UMIK-1, UMIK-2, and EARS microphones. In addition to real-time sound level measurements, SoundMeter can stream raw sound data to audio files, and store acquired sound level data, including date, time, and location, in CSV or TXT (tab-delimited) files, MAT-files, or high-resolution PDF images for later retrieval from your device. SoundMeter may be downloaded for free from the App Store. Additional tools and features are offered via in-app purchase. The SoundMeter Pro subscription includes: - User-defined custom metadata in saved audio and data files - Level MeterLp, Leq, Lx sound levels -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. -- Event notifications - Max Levels Meter -- Traffic-light-style meters make it easy to monitor 2 separate sound level thresholds in 2 independent user-defined frequency bands. -- Define lower (warning) and higher (limit) sound level thresholds for overall (full audio band) levels as well as for individual octave frequency bands. -- Store user-defined thresholds in files for later recall. - Noise Dosimeter -- 8-hour Noise Dose, Projected Dose, TWA calculations -- Criterion Levels: 80, 85, 90 dB -- Exchange Rates: 3, 4, 5 dB -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. - Real-time Octave Spectrum Analyzer (RTA) -- Lp, Leq, Lx sound levels -- Supports whole or 1/3-octave frequency bands -- Standard Flat, A, C frequency weighting -- Standard Fast, Slow, Impulse time weighting -- NC, RNC, and NR references curves, NC, SIL, and NR values -- Data logging. Data can be logged as often as every 0.1 seconds for up to 8 hours, every second for up to 72 hours, or every 10 seconds for up to two weeks. - Multi-channel Data Recorder -- Supports up to 8 channels -- Live monitoring of recorded data -- Metadata (including calibrated sensitivity) embedded in audio file (AIF, CAF, WAV), optionally saved in separate data file - Stereo Signal Generator -- Left and right outputs assigned to arbitrary hardware output channels -- Random and pseudorandom (periodic) noise sequences with white or pink spectrum -- Linear and logarithmic frequency sweeps -- Dual periodic waveforms with arbitrary frequency and phase difference - MultiTool -- Powerful data monitoring and project management (Add up to 6 subtools and save configurations for easy recall at a later time.)

Protect your deposit. Prove the condition. Never pay for damage you didn't cause. Whether you're moving out of a rental, ending an Airbnb stay, or turning over a unit between guests — RoomProof gives you dated, side-by-side photo proof of exactly how a room looked, and uses AI to flag anything that changed. HOW IT WORKS 1. Create a space — "Apartment 4B", "Airbnb Lisbon", "Move-out Mar 1". 2. Take a "before" photo when you move in (or before guests arrive). 3. Take an "after" photo when you leave (or after checkout). 4. RoomProof's AI compares the two and highlights anything that moved, appeared, or went missing — right on the image. WHY PEOPLE USE ROOMPROOF • Get your deposit back — timestamped before/after proof settles "who broke it" disputes instantly. • Catch what the eye misses — a chip, a stain, a missing item, a moved object. The AI compares the objects, not the pixels, so a slightly different angle still works. • Two photos, a few seconds — no forms, no checklists, no account. • Your proof, kept — every check is saved with before + after side by side and the changes marked. • Works from any angle — it even warns you when a shot is too far off to compare reliably. PERFECT FOR • Renters protecting a security deposit at move-in and move-out • Airbnb & short-term rental guests documenting a room on arrival and departure • Hosts & landlords recording condition between guests or tenants • Travelers who want peace of mind that nothing was touched while they were out Stop losing deposits to charges you can't disprove. Take two photos and have the proof. Checks are paid with simple credit packs — buy once, use anytime, nothing recurring. Privacy Policy: https://roomproof.yozatapps.com/privacy
