Pinboard is a web service that allows users to bookmark and cache webpages easily. While it has a full suite of social features, it also can be used fully privately.

Sadly, Pinboard isn't the most beautiful service on the web. It loads fine in Safari on iOS, but isn't the easiest way to interact with bookmarks.

Pushpin is a great iOS app that solves this problem. In addition to allowing users to browse, search, add, edit, and delete bookmarks on the go, it's a great way to filter content from other users, share with services like Instapaper, Pocket, Evernote and Twitter.

Check it out on the iOS App Store, where the universal app is $9.99.
