Infinirule Virtual Slide Rule

Infinirule Virtual Slide Rule


Infinirule is a virtual slide rule application for Android. It transcends the limitations of real physical slide rules by allowing variable precision--just keep zooming in to get more--and automatically wrapping scales around--like a circular slide rule, but without the bulk. And though it only shows four scales at a time, you can select any combination of the available scale types.

Free Software (GPL).

Recent changes:
16254.1: padlock button to lock slide to body; new scales: 1/(πx) (CIF/DIF), acos° < 8°, √x and √10x (R₁ and R₂), separate asin and atan; long-tap on scales no longer brings up useless legacy message; new 3D-style app icon.

15919.0: support action bar on post-Gingerbread systems; fix one source of crashes; colour-code descending scales in help; drop support for Android 2.1 because of crashing system bug.

A Tool, Not a Toy It's clear Infinirule was developed to be a serious computational tool and not a toy, unlike most other slide rule apps. Expect to be frustrated until you learn these controls, but once you get the hang of it, this thing really is powerful. It will be as accurate as you want it to be, from quick-and-dirty to five or more significant digits. I docked 1 star because the menu that pops up if your finger rests on the screen too long while making a fine adjustment is really annoying. If that could be turned off, this would easily rate 5 stars. If you need to be sure you're getting correct answers and you want to have more fun than stabbing buttons on a calculator, this is the best slide rule app out there.

Finalmente entendi como funciona essa !#%!%. Há anos espero algum modo inteligente de aprender os princípios por trás da régua de cálculo. Esse app cumpre o papel com maestria e sem a chatice de se carregar régua de cálculo para todo lugar. Obviamente não pretendo usá-la como substituto da calculadora, mas por mim valeu cada segundo gasto.

Feels like an alpha version. No zoom or precision controls. Only two scales. Lack of ads and small download size do not make up for lack of features.
