About this app

* An app simulating a slide rule! *

Smart Slide Rule reproduces a slide rule (slipstick) with A, B, C, CI, D, S, L, T, and K scales.
A slide rule is a mechanical analog calculating tool that uses the principle of logarithms.
The slide rule appears as an important prop in the movies "Apollo 13" and "The Wind Rises".
This application reproduces a slide rule on the screen of your device.
The front side of the slide strip corresponds to the B, C, and CI scales, and the back side corresponds to the S, L, and T scales.
You can move the slide strip and the cursor.

* With instructions on how to use the slide rule! *

The slide rule uses a logarithmic scale to calculate multiplication, division, exponentiation, square root, and trigonometric and logarithmic functions.
This application features an explanation of how to use the slide rule, so you can learn how to calculate.
Since the calculation is performed in pixels of the device screen, the accuracy of the calculation cannot be guaranteed.

The slide rule part of the app is clean and simple but the instructions could be improved. As one of the important uses of this app is educational I think some extra effort in teaching how to use a slide rule would be well worth while to make this a really great app. I hope the developers continue this them as there are many mechanical mathematics machines I would like to experience.

The young always-online generation needs a good digital emulation of an old-fashioned carry-it-anywhere analogue calculator. Sorry to say that, without much more attention, this app isn't it. Apart from the controllability issues on this (quite up-to-date in NW Europe) smartphone, the trig scales seem odd (e.g. S-scale angles appear to correspond to values on the A-scale, rather than on the D-scale). For now, I'll be sticking to my good old-fashioned (circa 1973) physical slip-stick.
