A neat little iTunes and App Store wishlist app that lets you save applications, music, movies, TV shows, and more for later. I started using the app about a week ago and it’s a huge improvement over my old method — creating a new note in Simplenote every time I found something I wanted to return to. And with an in-app purchase of $4.99, Lookmark will send a push notification whenever something you’ve saved goes on sale in the next six months.
