For the past weeks I've been working on a brand new OS X app and now I'm finally able to announce it: Ceceree.
Ceceree lets you easily create lists of apps available on iTunes, keep track of the apps you're interested in and share your lists with others.
If you're interested in Ceceree and want to get notified when it's available, please sign up on the bottom of the page. I've also posted it on ProductHunt. I'd love to hear your impressions, feel free to contact me!
