iSlideRule

iSlideRule is a simple 12-scale slide rule application, with the scales configurable via the "Settings" application on the iPhone™ or iPod® Touch devices from Apple, Inc. Currently, it is supported on the iPhone and iPod Touch.

See the new weblog for more information on requirements, updates, and upcoming features of iSlideRule. I appreciate the support and feedback received. If you haven't already, please consider reviewing the application on Apple's App store as well, whether you like the app, or not. Feedback here, and there, is very much appreciated (both good and bad! I can't improve things if I don't know that they're "broken"! THANKS!!!)

Configurable Rules

Each of the three rules of the slide rule can have up to 4 scales configured and placed on it. By default, each rule has 4 pre-selected scales. The default scale configuration of the application has the following settings. For more information on scales added in updates, see the relevant log entry (linked by version number):

Top Rule: "A", "K1", "S", and "ST" scales enabled
Other scales that can be placed on the top rule: "DF", "LL", "P", "LL\0", "LL\1", "LL\2", "LL\3", "T1", "T2", "LL0", "LL1", "LL2", "LL3", and "L".
In the 1.0.2 update, added additional scales: "DIF", "S(mannheim)", "Ln", and "F(2π)".

Bottom Rule: "D", "R1", "R2", and "Q1" scales enabled
Other scales that can be placed on the bottom rule: "DF", "DI", "P", "S", "ST", "Q2", "Q3", "LL0", "LL1", "LL2", "LL3", "SH1", "SH2", and "TH".

In the 1.0.2 update, added additional scale: "CIF".

Using Settings

When the default settings are not what you need, launch "Settings" from the home screen on your handheld. Scroll down to the area for changing application settings and select "iSlideRule". The following screen will appear.

To change the rules, select the desired rule, and view the list of selectable scales for that rule. You may select up to four scales for each of the three rules. Selecting fewer scales will result in a blank space inserted in that area of the specific rule.

      

The color scheme can be changed to provide a different look to your slide rule. Select from one of eleven different colors; blue, red, yellow, green, orange, purple, gray, cyan, magenta, brown, or white. Additionally, the slide itself may either be slightly colored to match the selected color scheme, or can be just white. The color and slide color can be selected from the main settings screen for the application. Colors are selected from a submenu.

Here are some sample screenshots showing the different orientations, colors, and scale changes. Nearly any type of slide rule can be configured with this application, for most common slide rule uses. For more information on slide rules, there are numerous websites available on the Internet, some with extensive libraries of guidebooks and tutorials on the use of slide rules. Simply search for "slide rule" using your favorite search engine and enjoy!
