If you are reviewing creator tools, DJ apps, or practical audio utilities, LevelCheck is an acoustic advisor — not a commodity decibel meter. It offers 25 guided room and booth checks, plain-English recommendations, Fix-Verify comparisons, and optional Pro depth (LiDAR room scan, AR speaker placement, external mic calibration). The App Clip at levelcheck.live/clip lets reviewers try the meter before install. Privacy story: measurement data stays on-device; no audio is recorded or transmitted.
