Voxer Remember walkie talkies? They were the coolest, back in the day. (I recall using them on the ski slopes...before cell phones)! These days, Voxer aims to be a modern walkie talkie. Voxer's app lets you send audio messages to friends anywhere. There's no need to call and wait for it to hit voicemail. Send a photo while you're at it. Voxer also makes it easy to send texts. The best thing about Voxer is it lets you send audio messages to groups. Instead of calling all your friends and leaving voicemails, just record a quick voice note to share the same story with everyone. Keep the conversation flowing, by saving all your close friends in one group. In this era of typing and texting, sometimes it's just better to hear someone's voice. This free app is compatible with iPhone, iPod touch, and iPad, and requires iOS 5.0 or later. It's also available for Android.
