Bitcoin Balance Scanner is a free application on the Android Market that allows you to scan a QR code of a public Bitcoin address. This will then use the BlockChain API to lookup the current balance. History is saved to allow quick and easy lookups.
Not much more I can say about it, it's simple and to the point.
This is the product of about 4 hours of work, so it has the ability to grow based on suggestions.
Get it on the Android market:
