User reviews

Only metric

Bought the app but no option for imperial measurements

Doesnโ€™t work

Gives me wrong pulley size ever time

Perfect, but only metric units

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. Shouldnโ€™t make a difference for speeds, but belt speed isnโ€™t useable without conversions. Wish there was a toggle to convert to imperial measurements
