Best Messaging App: WhatsApp
Sure, you can send messages and pictures with your phone's regular texting service, but a full-featured messaging app lets you send richer content, such as location info, fun stickers and more. With Whatsapp, you can also chat with up to 50 friends in a group to organize reunions or potluck dinners. And when those large conferences get out of hand, you can leave the group or mute the conversation for up to a week. Set statuses so your friends know when to leave you alone. The new iOS 7 version packs a Facebook-like broadcast list feature on top of a fresh sleek look.
