Slide Rule for Android

no log, no star!! (j/k)

Would like the slide rule to remember its position (calculation) when leaving and returning to it. Would like to be able to rotate to all four orientations. Would like support for full Mobile resolution. Please continue compatibility with iOs 3.1.x If I put a value of 4 on B scale under 2 on A scale and look at B scale under 5 on A scale, it does not quite line up to the expected value of 10. Looking forward to these modifications to upgrade my rating to 5 stars. Thank you.

The D scale is wrong. The spacing after pi is wrong, so the C and D scales cannot line up. Pass this by until it is fixed. Pray for Japan.

I installed this mainly for it's inherent irony. I have no idea how it works, well I sorta do just by looking at it, but these predate me. I suspect the missing Trig scales would be on the opposite side of a real one, but that's just a guess. Anyway it is totally cool!

I'm a 20-something engineer, and each year during Engineering Week, my workplace holds a slide rule competition to see who in the office can solve math problems using a slide rule. I like learning useless skills, so I decided to learn how to use a slide rule so I could compete. I found this app last year and it was awesome! It's also a good way to introduce the younger generation to this out-of-date math tool. The only problem I have with this app is that it doesn't include a trig scales or the log scale. Not only would adding those scales improve the quality of the app, but it will also allow me to use the app in the competition (because it always includes trig and log problems). -Jason
