I wouldn't have thought it was possible to get an iPhone to capture barcodes clearly, but Occipital has done it with a new $1.99US iPhone app called RedLaser [App Store]. Why capture barcodes? One good use is to find better prices for a product. Scan a product in the store, then RedLaser captures the barcode and does a quick Google or Amazon search to give you quick price comparisons.

I tried the app at a bookstore and my local Best Buy and was surprised how well it worked. You need pretty good light to capture a barcode, which is an issue with the iPhone camera, not the RedLaser software. You need to hold the camera steady. The best way is by holding down the button to take the picture, then release when you are steady.

RedLaser gives you the option to try again, and guides you on how far the camera needs to be away from the barcode. Then RedLaser instantly goes out to the internet and gets you the price comparisons.

In practice I had some misses. The camera wasn't at quite the right distance, or I was a bit shaky holding it. In most instances, however, I was able to get the barcode and see the price comparisons I was looking for. It's also important that the camera not be tilted in relation to the barcode. Try to keep everything lined up. And the app will not work at all unless you have an internet connection. It would be nice if it could store the barcodes, then go out and identify them when you have a good signal.

You also get the ability to mail your product list to yourself or a friend to read it on a bigger screen when you get home.

The clever technology in the app is able to sharpen the image a great deal, making the iPhone camera a feasible platform for this app. When you take the picture the barcode will look pretty fuzzy, but after a couple of seconds of processing it looks quite good, which is the magic that RedLaser accomplishes.

I'd expect this will work fine for most people, but there are some negative comments at the iTunes store as well, largely, I suspect, from people who couldn't hold it steady, had bad light, or glare falling across the barcode. When I eliminated those issues, it seemed to work fine.

Note: This app only recognizes US and UK UPC and EAN barcodes. It works works best on standard-sized barcodes, but I had success with some smaller ones as well.

Here's are some screen shots of RedLaser in action:

kip is one of the few applications to take a real stab at helping you organize all your documents, both digital and 'real world'. It combines the look and feel of iPhoto with the real world aggregate paradigm of Delicious Library, then tosses in some really slick tagging and .Mac syncing features for that finishing shine. On the left is a dynamically scaling tag cloud that keeps track of all the tags you've used on all documents. Mouse over it and smaller tags will scale up in size to help you read them better. Mouse over a document (as you see in the screenshot) and a live preview of that section of the document is displayed next to your mouse. Documents can be viewed from within kip or opened externally via Preview.

The 'real world' aspect enters the scene when kip's scan function is used, as this app wants to help you organize all your documents, including those receipts and old tax returns that are just decomposing in a box somewhere.

One of the drawbacks I've found after poking around with kip is that it seems very focused in the kinds of files it will accept. It takes picture files and PDFs, but not text files or (not surprisingly) Word docs. Overall though, this is a clever app with a nice implementation. It offers a lot of handy methods for storing all sorts of metadata, including author and URL, and seems to be one of the first i-app-like applications to do tagging well (hint hint, Apple!).

This initial version of kip is free, but as its product site plainly states: the next version will require the purchase of a license, with the price TBD. Grab a copy while it's hot, and free!
