It is a great app. The only thing that could make it better would be if you could freeze the thread as you scrolled over to see all the way to your clearance fits.

This software is quite vital at work where I rely on it for programming and setting up CNC machines, as well as performing maintenance machine shop work. No annoying ads means no leeching of my data, so that is a plus.

The chart is great, however, an inbeded tap drill size calculator would be cool too for calculating special non standard tap drill sizes.

Really easy to read layout. Haven't had to use it yet, but it's already better than any that come up when using google. Definitely love the "closest to" for jumping between metric and English.

The app itself is very well laid out, but there is no metric tap/drill chart. So you can look up what the direct sizes are but you still have to find what drill to use for metric. Other than that it looks very nice. For a metric chart use the FSWizard Lite app. I found they have a nice chart for metric there using the common US drill sizes when necessary. I only use these once in a blue moon but it's very handy to have the information when you need it.
