NoiseCheck turns your iPhone into a fast, accurate sound level meter. Open it and instantly see how loud your environment really is, at work, in your apartment, at concerts and events, in the studio, or anywhere noise matters. A big, high-contrast dB(A) reading you can check at a glance, with color-coded zones that tell you immediately whether a space is safe, getting loud, or loud enough to harm your hearing.

Note: iPhone microphones vary, so for absolute accuracy calibrate against a reference meter; relative readings and zone behavior are reliable out of the box. NoiseCheck is a practical noise-measurement tool, not a certified sound level meter for occupational compliance.
