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

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!
