Very useful, very helpful, one issue v

I'm a systems geek, and this is an exceptionally useful calculator. Pretty much everything I need is here, and it's well laid-out.

But I have one problem, and it's the same one I have with mist calculator apps -- VoiceOver integration is terrible. I'm visually handicapped, and VO is helpful. I would love to see someone step up to the plate and do a good job of implementing it, and it would be great if it ere this app.

Otherwise, fantastic.

5/5 stars


Best engineering calculator!
