If there's one thing expectant parents and moms of young children do a lot of, it's write thank-you notes (hello, baby gifts!), and Felt (free) makes the process easy and fun. The app lets you write and send handwritten, stamped cards and photos in the real mail, all from your iPad. Pick a card, with or without photos from your library, handwrite a message with your finger or stylus, address the envelope in your own handwriting, and Felt will send your message within 24 hours. Your first card is free and each card after that is $3 to $6, depending on size and style.
