This is a useful app and certainly worth more than $4.99 to most people who need it. I wish he annotated the graph to show how sales numbers varied with the sales price.

Personally, I'd have a separate site that marketed the product and then directed purchasers to the AppStore. Getting less than $19.99 for something this useful is ridiculous! Make it easy to use with automatic whiteboard cleanup, annotations, and target it to the right industry and it should be worth a lot more.

That's a good suggestion to annotate the graph to show price changes. I'll whip one up and post it later. Thanks.

This sounds like the type of software in the App store that can set a high price and supply a free version. How about a $14.99-ish price and a free version that does everything but stamps it with a watermark? It's a perfect demo which shows the full functionality yet the users will not be able to use it without paying.

Have you considered doing something similar for business cards?

It's hard to do this for business cards due to the combination of low-resolution of the built-in camera and the focal length of the lens.

It's possible using something like Griffin's Clarifi (macro lens), but you can't count on everyone having one.

Exactly. I'm optimistic the next major revision of the iPhone hardware will have a better camera so maybe then.

Just stumbled upon http://cloudcontacts.com

It's not mobile though

I'm sorry if this is a redundant question on HN, but what did you use to create the graphs?

They're from AppViz. It's an application for the Mac that parses App Store reports and generates graphs/etc from them.

those graphs look really similar to the protochart defaults

Glad I asked, AppViz looks like an excellent tool. Thanks!
