QuietScore vs SpettroLive

QuietScore measures how much noise your doors and windows actually block: a Sound Isolation Score in about 60 seconds, using your iPhone and a Bluetooth or AirPlay speaker. No lab equipment, no calibration, no sign-up. It is a practical estimate, on a scale comparable to professional STC ratings, and it is the number that tells you whether to sign the lease, whether your conference calls can be heard from the next room, whether the studio treatment worked, or whether last weekend's weatherstripping did anything at all. HOW IT WORKS 1. Put a Bluetooth or AirPlay speaker inside the room 2. Step outside with your phone and take a reading with the door open 3. Close the door and take the second reading The app plays test tones through the speaker and measures how much of them survives the trip through your door or window. Same spot for both readings, only the door changes: your score is the difference between the two, which is why nothing needs calibrating. About 60 seconds once the speaker is connected. WHAT YOU GET • Sound Isolation Score, one number for the whole door or window • Privacy Rating: Excellent, Good, Moderate or Poor • Four-tone breakdown — 125 Hz, 500 Hz, 1 kHz and 4 kHz, so you can see whether it's bass, HVAC hum or speech that gets through • Rooms and history — save each result to a room, add a note about what you changed, and see the difference since the last measurement • PDF reports — export a result to hand to a contractor, a landlord or a client LEAK SCANNER Sound rarely comes through the wall. It comes through the gap. Sweep your phone along a door or window frame and the scanner reads the leak live against a baseline spot you set, so you can hear and see the moment it jumps. Mark the hot spots as you find them and they collect into a findings list. Two modes: play a tone from inside, or listen passively to whatever noise is already out there. The scanner locates leaks — it doesn't score the door. THE FIRST 3 ARE FREE Your first 3 Sound Isolation Scores are free, with no account and no trial clock. After that the measurement still runs and the score unlocks with a plan. A retake spends one of your three; a run we can't stand behind, interrupted or too noisy to trust, doesn't. The app shows what you have left before you start. PLANS • Home — unlimited QuietScores, the four-tone breakdown, saved rooms with history and notes, the full Leak Scanner and PDF export • Studio — everything in Home, plus raw dB figures and USB reference-microphone support • Business — everything in Studio, plus branded, client-ready PDF reports FOR PROFESSIONALS QuietScore Business is built for acoustic consultants, property managers, contractors and studio builders who need a number in front of a client before the expensive work starts, with their own name on the report rather than ours. Measure room by room on a single visit, save each to its own record, and export a branded PDF the same afternoon. Every report carries your logo and company name, with fields for the client, site address, project ID and anything else the job needs. Works with any Bluetooth or AirPlay speaker, on iPhone and iPad. Your measurements stay on your device. The Sound Isolation Score is a practical estimate, measured with your phone instead of lab equipment rather than certified by it. It is the number you use to decide what to fix, show what changed, and give a client an answer the same day. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
