Virtual Slide Rule

As an Electrical Engineering student before calculators these were a mandatory tool for most engineering courses.

This should easily be my favorite slide rule app, as this was the rule I used in electronics school and for years later. This app works great, except for one flaw - the top cursor rail protrudes down into the top scale. This simply should not be. The bottom rail is as it should be, not interfering at all. Other than this one irritating issue, the rule looks great, is easy to read and use. It’s almost perfect.

In high school and college my slide rule was an essential tool in Chemistry. Physics, and Math classes. Now I have this really cool reincarnation of a classic and it works great on the iPad. It also brings back all the great memories of those times back in school. And if you've never used a slide rule, the instructions make it straightforward to learn. And for those Millennials in the crowd, it's a unique app to have on your iPad. Kudos to Interrobang Group!

Had a hard time believing my eyes...make that my anal eyes. Woke my wife up searching for my ancient Dietzgen multiplex manual. Found it though and this app is guaranteed to keep me up all night. Great app though I'm worried there aren't enough of us old dudes left to give it it's well deserved appreciation.

This is really a fantastic app. It works exactly like the real thing, and it is terrific to look at. It's a great app for a math or science teacher to show to his class. This app keeps a part of math history alive. I love it.
