My Favorite iPhone Apps

Here's a short list of my iPhone favorites:

1) United Airlines -- great app if you regularly fly on United. It allows you to check-in to flights, display QR boarding passes, change seats, and more.
2) Clear -- intuitive To Do list manager. Very innovative user interface and syncs via iCloud with the Mac version of the app.
3) Yelp -- very useful app to find great places to eat near home or while traveling.
4) Instagram -- an app that lets you share photos with others. Large community of users.
