Great little app

So convenient having screw cutting info at hand with just a few spins of the selection wheel

I’ve used this since it was first released and like the new look

Loads of threads added but I mostly refer to the metric ones

Just hope they add Acme soon

Great app👍👍

This app has provided everything I have asked it to. It has more thread dimensions than I will ever use. For a couple of dollars it cannot be beat. Also I do not like to soil my expensive reference material. With this app I can just give my phone a quick wipe down.

Poor

Don’t bother all sizes are in imperial for a metric app this is rubbish

Terrible

Every size I need info on is not there, better just stick to the machinist handbook!
