My slightly more than weekend project

I run a few calculations over and over again, and got tired of doing so. So I made a little app, the kicker is that the calculations are expressed in lispy like syntax. I thought HN might enjoy it. It is free and yes needs work. I did the absolute minium to get it out.

    My $0.02:

    Cool concept. I remember when I did construction, I had to do calculations all the time, and something like this would be cool. That being said, here were my first impressions:

    --I didn't know that you can make your own calculations until after I downloaded the app, and after I did some digging. If it wasn't cause I was trying to help someone on HN, I probably wouldn't have downloaded it.

    -- Make it more obvious how to add a new calculation. If the edit button is on the upper right, add a "+" button to the upper left. This is what your user will expect.

    -- I like the Lisp syntax for the code. But I'm a nerd. This really limits your audience. Make it look like something a person would see on a high school math board and you will have more luck. Something like: @result@ = @variable1@ * ( @variable2@ + 4.5 )

    These are just my first impressions. I think it's cool, and just needs some iterations to be really good. If you get a chance, check out my app, and feel free to give some feedback http://itunes.apple.com/us/app/follow-my-money/id471808412?l...
