Observe vibration. Explore its frequencies. Keep a record of change.

Oscivra uses your iPhone's built-in motion sensors to capture three-axis acceleration and organize measurements around your equipment. Follow a complete workflow from machine profiles and live capture to frequency analysis, baseline comparisons and shareable reports.

A WORKSPACE FOR YOUR EQUIPMENT
Create profiles for motors, fans, pumps, compressors, machine tools or custom equipment. Record operating speed, location and reference parameters. Add measurement points, direction, mounting details, equipment photos and position markers.

REAL SENSOR CAPTURE
Capture X, Y and Z acceleration using gravity-compensated user acceleration or raw accelerometer data. Set the requested sample rate, recording duration and placement countdown. Watch live waveforms and X-axis RMS, peak and peak-to-peak statistics. Pause the display while acquisition continues.

EXPLORE THE SIGNAL
Browse saved waveforms with zoom, pan and time cursors. Select an interval to calculate RMS, peak, peak-to-peak and mean values for the selected axis or vector magnitude.

Use FFT spectra to inspect dominant frequency components. Choose Hann, Hamming or rectangular windows, adjust the FFT length when enough samples are available, and enable segment averaging. Inspect frequency and amplitude with a cursor, or add harmonic and RPM-based reference lines.

SEE FREQUENCY OVER TIME
Explore a spectrum waterfall with frequency-range and time-window controls. Inspect individual time slices and read the amplitude color scale.

BUILD A BASELINE
Save named baseline versions and compare two measurements. Overlay spectra, review changes in acceleration statistics and check the recorded measurement conditions. Follow per-machine RMS or peak trends and add observation or maintenance notes with photo attachments.

KEEP AND SHARE YOUR WORK
Generate measurement, comparison and historical trend PDF reports. Export raw acceleration or spectrum CSV files and annotated chart PNG images. Use local backup and restore, choose whether to retain raw samples, and display acceleration in m/s² or g.

OFFLINE BY DESIGN
No account is required. Measurements, notes and photos are stored locally. Sharing and backup exports are initiated by you. Clearly labeled generated examples let you explore the workflow before taking your own measurements.

KNOW THE MEASUREMENT LIMITS
Real capture requires a compatible physical iPhone. Actual sample rate is calculated from sensor timestamps, and the displayed frequency range is limited by that rate. Sensor hardware, mounting, contact and operating conditions affect the results. Features that reprocess samples require retained raw data.

Oscivra supports preliminary vibration observation and trend recording. An iPhone is not a calibrated industrial vibration analyzer. The app does not diagnose equipment faults, certify safety or apply industrial vibration severity standards. Acceleration values are not vibration velocity or displacement measurements. Use only safe, stable measurement positions away from moving parts and hot surfaces.
