The slide rule was used for over 400 years as a calculating/estimation tool. Abandoned with the advent of hand-held calculators, computers and smart phones, their elegant simplicity is still a thing of wonderment. This program replicates the most common types of slide rules: Straight, circular, spiral and cylindrical. Dozens of scales are included and numerous features that could never exist on a physical slide rule are also included, such as color options, numeric displays of the values under the hairlines, and so on.

Slide rules were used to go to the moon and to build bridges, skyscrapers, tunnels, aqueducts and nearly everything else. Slide rules were simple to use and accurate enough for most occasions. 

Please note that this program is processor-intensive and with heavy use, will probably drain your battery fairly quickly. Every effort has been made to make the program efficient, but nevertheless, some functions take a few moments to occur, including initial load, which can take three or four seconds, or perhaps a little longer. Nearly 30,000 "nibs" are created during this time, as well as over 3,000 labels, so please be a little patient!

Because of all the detail, it looks best and runs best on a large-format machine such as a tablet. Also because of all the detail, the 30-loop spiral slide rule converts to a low-rez "bitmap data image" while you move it, then back to a "vector based image" as soon as you release.

Includes a brief side show slide show of famous and interesting slide rules, most of which are in the author's collection. Two are public-domain photographs of antique slide rules.

---------------------------------------------------------

Notes on usage: Program features include "two-finger pinch/zoom." Slide rule slide show images can also be rotated. Enlarge an image by double-tapping in the same place. Tapping three times in the same place will return the program to the home position. Tapping four times will bring up an intro-screen message which requires tapping anywhere to remove.

----------------------------------------------------------

This program was first released in 2016 and is the product of a lifelong love of numbers (and 30+ years of programming experience!).

Special thanks to the Oughtred Society for their member's invaluable help in evaluating the earliest versions of this program.

    I should say that this app is a nicely animated historical lesson on how to estimate multiplication & division using rulers. It's very interesting though if I want to fiddle around more easily, I should but a slide rule by myself and learn from its manual book. Why? Because of the sensitivity of the screen, it's hard for me to align the small lines.

    Slide rules are still handy for getting a quick and dirty estimate of the answer to a complicated problem. This app, however, doesn't give that experience. It's cumbersome to use, zooming is not ideal for this use case. The circular slide rule works well due to limited screen space and should probably be the default, but the controls are still tricky to master.

    Exceptional graphics and animation! Could I just type in "2 * 3", for example, and just have the app display the ruler in a solved position? I won't have to spend time sliding the ruler myself using the touch screen. Thanks.

    Needs to sell a no ads version. I find advertising in general an offence on my senses!

    Thanks for your reply, developer. 2 more stars. But no 5th star until there is a way to get rid of ads. I hate ads.

    Really cool overview of slide rule history, types, and use. The developer put a lot of thought into this.

    Good app to learn the basics of using a slide rule. A little clumsy on a touch screen(for old aged hands).

    Works great! Oh sure a real slide rule would be faster, but for a phone (s8) screen it's terrific. And fun to try to remember how to do things on a slide rule

    3 stars for the great idea, but (at least for me) an awful user experience. Feels extremely sluggish and impractical

    Why does a slide rule app need my WiFi information? Thanks for explaining why it needs it. Changed rating accordingly. Thanks for putting so many hours into this app.
