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.

Siamo i ragazzi dell'Istituto ALGERI MARINO di Casoli (CH), l'obiettivo di questo sito è dimostrare quanto sia importante comunicare e trasmettere le nostre riflessioni attraverso la lettura dei giornali e la partecipazione agli eventi organizzati nella nostra scuola. L'idea di digitalizzare articoli ed esperienze nasce dal progetto sostenuto dall'Osservatorio "giovani editori" www.osservatorionline.it a cui la la professoressa De Risio Amalia, docente di lettere, ha aderito e che si inserisce nel PNSD (Piano Nazionale Scuola Digitale) coordinato dal prof.re Iezzi Rocco. All'interno del sito troverete i nostri contribuiti su svariate tematiche...e chissà, un giorno, qualcuno di noi sceglierà di fare il giornalista ...Mai dire mai!

Verdict
The clearest difference is update cadence: Caffè Marino at every 10 days against VibraUnits's every 10 months. VibraUnits's advantage is iOS requirement (7.0 vs 14.0). On price, ads, in-app purchases and device support there is nothing between them.
