Customer Reviews

Great RPM counter.

I work in a machine shop with several '40s and 50's vintage boring mills and vertical lathes. Setting the spindle RPM on these machines is by the "By guess and by golly method". About the only way to get an accurate idea how fast the thing us turning is to break out the stopwatch and time it for a minute counting how many times it comes around.

This App is almost perfect for my needs. Most of my tools run below 300 rpm. By knowing its diameter and how fast it's turning, it's a quick calculation to come up with a surface feet per minute value. Most of the time our machinists are running their spindles way too slow for their cutting tools because they have no idea how fast the spindle is turning.

The one thing I'd like to see is one decimal place for 30 beats per minute or less. When an 8 foot vertical lathe table is spinning on a big part, the surface foot calculations make a big jump between 2 and 3 RPM.

The nice bonus about this App is that it works just fine on my 2nd gen. iPod touch. I am not allowed to bring a camera / camera phone onto company property.

Used to work

This app used to work great, but for the past few months, the BMP count will sometimes not show certain digits... The numbers just disappear, and will just show blank black spaces. Please fix this!


This is just what I was looking for. Very basic and works as described.
