An electronic version of the Engineering Slide Chart. Works just like an actual slide chart to provide a user-friendly interface. Includes technical information from many of the quick references that are commonly found in the work areas of designers, engineers, and machinists. All of this information is compiled for both Imperial (English) and Metric systems in a single screw chart App.

Pretty nice app that could use a tiny bit of polish

There is a lot of useful information in this app for engineers, mechanics, etc. It's obviously more portable than the full-size physical version, but might take a little longer to get to the info you need (an extra few seconds).

The first thing I noticed that I would love to see improved in an update would be to allow swiping sideways to move through the charts instead of having to hit the buttons at the top of the screen. It would be much more intuitive to use that way on the iPhone and seems like a no-brainer.

Overall, a really nice app.

Excellent and Useful

Great 2015 new and improved App. Has Metric and Imperial screw data. Also includes new data on this version: clearance holes, wrench clearances, spring pins, drilled hole tolerances, miniature screws... Too much to list. The slide bar at the bottom moves data around smoothly. Clear graphics. I recommend this App. iPad version is almost as big as the plastic chart!

Updated at last!

this was an app I referred to everyday at work.

unfortunately after the iPhones started updating with larger screens it seemed like it was abandoned without an update.

Now it is installed back in my dock and os essential to my daily engineering tasks.

My only wish is that it could support the new split screen view. (actually I havent tested that though)

Thank you so much for revisiting.
