No more annoying cut sheets

Who does math by hand anymore? This app saves you from having to ever fill out a bitting chart again. Quick and easy!

Awesome app

This app pays for itself over and over and over. I’ve rekeyed 4 casinos and a airport using this handy app cuts my bitting generation times in half. The control finder is an added bonus in tight situations as well. Thanks Phil!

Great tool

Great app

Great app, it is very well thought out. It's interface/layout/GUI whatever you call it in an app is intuitive and attractive. Works very well, I do not do the math for A2 systems often enough to be fast at it and this app is great in the field. Still the best!!

Excellent!

I don't know why it took me so long to think of searching the App Store for locksmith tools, but I'm glad I finally did. This app is fast, effective, and full-featured. I used to do all my SFIC calculations in a web interface tool, which was clunky, and ineffective when no internet was available. This not only works offline, but can do so much more, like calculate an unknown control key easily from the pin stacks in a core. It's easy to use for the basics and advanced features alike. This developer's other apps looks equally as useful. I taught myself long ago to do this stuff in my head, but my brain is fallible and slow, and sometimes just too tired to think. I'm looking forward to much increased efficiency when I'm working in the field.
