If it's a business, you might also see options like map, Yelp, Bing Local, Web search, and Twitter -- all incredibly handy stuff to have just one tap away.

For any contact you can also tap the accompanying CallApp icon for a pop-up list of powerful options: note, reminder, set meeting, share location, and so on. Or, if you just want to call that person, simply tap the phone icon.

What's especially nice is that CallApp works its magic with incoming calls as well, displaying as much information as possible about the person on the other end.

The app could use a few improvements. For starters, it displayed the wrong photo for at least one of my contacts -- though it did give me the chance to fix that. Also, it seems to work only with contacts that have phone numbers. I don't know about you, but my address book is full of number-less contacts, and I'd welcome the option of leveraging CallApp's capabilities with them as well.

If you've found Android's standard Contacts app lacking, especially in the social-media department, CallApp is well worth a look.
