VibraUnits vs Mechanical Formula
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
VibraUnits and Mechanical Formula both sit at 4.6 stars, but that hides the real split: 88% of VibraUnits's written reviews are positive against 0% of Mechanical Formula's. VibraUnits also leads on in-app purchases (none vs 1) and iOS requirement (7.0 vs 13.0). Mechanical Formula's advantage is update cadence (every 4 months vs every 10 months) and ratings volume (34 vs 9). On price, rating, ads and device support there is nothing between them.
