使用超过400年作为计算/估算工具计算尺。手持式计算器，电脑和智能手机的出现被遗弃的，他们的简约优雅仍然是惊奇的事情。这个程序复制最常见的类型的计算尺：直线，圆弧，螺旋和圆柱。秤的数十名包括在内，也包括可能从来没有在一个物理计算尺存在众多的功能，如颜色选项，在发丝下的数值的数值显示，依此类推。

计算尺被用来去月球，并建立桥梁，摩天大楼，隧道，引水渠和几乎一切。计算尺是简单易用，对于大多数场合不够准确。

请注意，此计划是处理器密集型和大量使用，可能会很快耗尽你的电池。我们已尽力做出让程序有效，但尽管如此，有些功能需要一些时间发生，包括初始加载，这可能需要三四秒，或更长的时间也许有点。近30000“笔尖”在此期间创建的，以及超过3000标签，所以请有点耐心！

因为所有的细节，它看起来最好，最佳运行大幅面的机器上，如平板电脑。也正因为所有的细节，而你只要你放开移动它，然后再返回到“基于矢量图像的”30环螺旋计算尺转换为低解析度“位图数据的图像。”

包括著名的和有趣的计算尺，其中大部分是作者的集合在一份简短的一面展示幻灯片。二是古董计算尺公共领域的照片。

使用注意事项：程序功能包括“双指捏/缩放”。计算尺幻灯片图像也可以旋转。放大由双攻丝的图像中的同一位置。在同一个地方攻丝三次将程序返回到起始位置。攻丝四次会弹出这需要随时随地攻丝移除片头屏幕上的信息。

这项计划最初是在2016年发布，是数字的终身热爱的产品（与30多年的编程经验！）。

特别感谢Oughtred学会在评价这一方案的最早版本，其成员的宝贵帮助。

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.

Every slide rule is animated. App can be moved to external SD memory. It even includes the rather rare "P" and "Q" scales, which solves for the Pythagorean theorem: Let P = 3, and Q = 4. Then P x Q = 5. With android smart phone models introduced after Jan 1, 2020, the sluggishness problem, related to computing new values, is now non-existent. I would gladly pay a fee to remove the ads.

Nice to show the grands how a slide rule interacts with a computer. I would not say it is a way to learn how to use the slide rule. I think it is better to learn to manipulate the physical slide rule. You can teach someone about the slide rule, but not HOW to use it.

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 more work. Some of us actually would like to use the app to do calculations rather than just learn about slide rules. If you just want to learn about slide rules then this app is probably for you.

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
