This is probably one of the best apps when it was working but I haven’t been able to open it with any phone or computer. Please fix this app.

Awesome app very quick to reference

Seriously, if you ever drill holes this reference will come in handy.

Very convenient. This is exactly what I was looking for to add to my other conversion Apps. English, Metric, Fractional & Decimal.

This will be well worth a buck the first time you have an empty slot in the drawer and you need to get as close as you can to that size. Now I won't have to hold up bits and squint to compare. I work the night shift at a forging shop and we have to fix or build whatever breaks. Now. There's no waiting for tomorrow to get an H bit or whatever from the supplier. Yeah, this'll be handy.

I like the various displays given, and especially liked the "All sizes" list that allows me to easily choose a drill size nearest what I want. One thing that could be added as a nice feature would be a drill size chart for tapping threads. A. very nice app worth the cost.

Simple, easy to use, very handy reference tool. Don't lose this as easily as my old reference card!

I got this thinking that I bet I wasted my money, but after messing with the app I think it's grate. There is not a lot to the app but it gets the job done.

Great little quick reference tool. Saves time having to track down a printed version. I agree with others that a tap size reference would be awesome as well.

As a metal fabricator I have to say this a handy app. Especially when working in the field away from my printed chart. I agree with another reviewer that a drill/tap add on would be great! Worth the buck I spent.
