Good App; small error
A fun rule to experiment with, given the multitude of scales you can set up. However, one thing I noticed is that the CIF scale is out of position relative to the other scales, whether it is on the slide or the stator, resulting in an error in calculations.
Hard to beat for free!
This is a wonderful introduction into what a slide rue can do and it is a great way to have one with you without the risk of it being damaged. Slide rules are not cheap today, as if the really ever were. Carrying one about can be a risk. Mine are very important to me. I do not want anything to happen to them so having one in the iPad is a significant boon. No it isn’t perfect, but then, it’s FREE!

The definitive slide rule app
Works exactly as described. Effective and intuitive interface, good use of screen space and touch controls. Sharp and clear scales. Nice customisation with scale options and colours. Actively updated. Most importantly, usable as an actual slide rule.
Fix the slide!
I have most of the slide rule apps. This one has much to recommend it. The size makes it easy to see and enhances the accuracy. I also like the numeric readings at the hairline. It is fully customizable to match most rules out there and it seems accurate. The problem is the slide is independent of the body. I move the slide to where I want it, then move the body and the slide doesn't go with it! You have to move the cursor to keep the slide in position. It's just not natural. When the body is moved, the slide must move with it. Period. Fix that and I'll give it five stars.
