It's a free apps that you can download on your mobile phone. After that, you can start send a voice recording to a friend who has the same apps on his or her phone. The person will play and hear your message.
It looks fun and cool to use it. Someone even commented that instead of typing the message, you could just speak onto the phone and send the message over. And you can hear the person's voice over and over again, especially you're lovers.
And then the brain starts rationalizing.
Why would anyone wants to send a recorded message to another person? If the person is lazy to type the message, wouldn't it be better to just call the other party?
Under what situations will people use this apps? Why would they want to use it in such situations? What are the benefits of using this apps? Will it be useful for boyfriends or girlfriends initiating a breakup? Wouldn't sending an SMS be easier and faster?
