I thought I would make this theme so that everyone could see each other's favorite paid/free app. Feel free to post screenshots and maybe an explanation of why this is your favorite.
My favorite app right now is (Vonage) it allows me to call and text friends and family in the US for free if the app is installed on their phone.

I have a favorite application with which can you fax from iphone. This is a really cool app that helps you scan and send documents in a few taps. Most importantly, it can send secure fax from anywhere, you just need to select files and phone number. This is one of the best apps, it has helped me out more than once.
