This little app Hey Tell allows you to use your phone like a walkie-talkie and leave small voice notes for your friends and family. Sure helps when you are walking and want to send someone a text, just push to talk. And it is FREE! You can, of course, add on a little bit and get the ability to “push your voice” out to multiple people. Could be handy for sending out reminders to a list of say, students. Just saying.
