## Most critical reviews (8 lowest-rated)

### 1/5 — Only metric

*2026-04-16*

Bought the app but no option for imperial measurements

### 1/5 — Doesn’t work

*2024-12-05*

Gives me wrong pulley size ever time

### 1/5 — Millimeter or what?

*2022-03-09*

Inches?

### 1/5 — What are we looking at

*2022-02-25*

What are the numbers? Are they Standard or metric? in inches or millimeters?

### 3/5 — Perfect, but only metric units

*2024-03-08*

This is an ideal app for simple speed calculations.  I volunteer with antique equipment association where we commonly use flat belt equipment.  There is a frequent need to do speed calculations for machinery.

My only complaint is that all units are in metric.  Shouldn’t make a difference for speeds, but belt speed isn’t useable without conversions.  Wish there was a toggle to convert to imperial measurements

### 3/5 — Great App, but needs one simple feature

*2018-10-07*

The app does exactly what it’s supposed to do, but needs the option to view/input imperial dimensions.

### 4/5 — Pulley Calc

*2021-07-16*

Works Great, But Needs Landscape Mode for iPad

### 5/5 — Great app.

*2021-12-23*

Simple. Never fails.
