VibraUnits vs Material Engineering
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
VibraUnits
This application facilitates the conversion of mechanical vibration analysis units. It supports conversions between displacement, velocity, and acceleration, along with frequency and various amplitude scales.
- Velocity, acceleration, displacement conversion
- Frequency conversion (Hz to CPM)
- Displacement conversion (mils to microns)
- Velocity conversion (inch/s to mm/s)
- Acceleration conversion (G's to m/s^2)

VibraUnits converts amplitudes of the most commonly used units in mechanical vibration analysis. The vibration equations used for changing units between displacement-velocity-acceleration only apply to vibration occurring at a discrete frequency (sinusoidal waves). Features: - Conversion between velocity, acceleration and displacement - Frequency conversion between Hz and CPM - Displacement conversion between mils and microns (RMS, 0-peak & peak-peak) - Velocity conversion between inch/s and mm/s (RMS, 0-peak & peak-peak) - Acceleration conversion between G's and m/s^2 (RMS, 0-peak & peak-peak) Disclaimer: This app is intended for educational purposes, although the calculations were made with great care, it may contain errors or inaccuracies. Using the results of the calculations is the responsibility of the user.

Verdict
The clearest difference is in-app purchases: VibraUnits at none against Material Engineering's 6. VibraUnits also leads on ratings volume (9 vs 1) and iOS requirement (7.0 vs 17.0). Material Engineering's advantage is rating (5.0 vs 4.6) and update cadence (every 3 months vs every 10 months). On price, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Material Engineering sells 6 in-app purchases, starting at $9.99 per month. VibraUnits asks for nothing beyond the download.
Material Engineering holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: VibraUnits has 9 ratings behind it against 1, so its average is the more settled of the two.
VibraUnits ships an update every 10 months, Material Engineering every 3 months. The most recent releases landed on September 22, 2026 and October 1, 2026 respectively.
