Jig Helper will help you figure out which settings to use with your woodworking jigs!

If you have a Kreg pocket hole jig, this is the app you need!
This app helps you determine what jig setting and what screw length to use in all common scenarios, including when you're mating workpieces of different thicknesses.

In addition, this first version comes with a handy conversion chart for common dimensional softwood lumber.
