Vibration Meter

Vibration Meter is a professional-grade vibration analysis tool that turns your phone into a precision instrument. Measure vibration intensity in real time with beautiful analog gauges, record seismic waveforms, analyze frequency spectra, and monitor vibration 24/7 — all from your pocket.

Whether you need to check floor vibration from construction, monitor earthquake activity, assess structural integrity, or detect environmental vibration — this app provides everything in one place.
