There's plenty of competition, from the likes of Skype and now WhatsApp, but HeyTell stands up well. A bit like voice texting, the sound is clear, and group conversations are possible too. There are add-ons too for extra fun.
The main functionality is great, and it's especially useful when friends who are in different timezones might be sleeping when you want to call them. The Voice Changer add-on is great when you're feeling a bit bored and want to have a laugh.
Sometimes it takes longer than it should to send or receive messages, presumably because of the file size. Of course, the fact that not many people have HeyTell restricts its usefulness, so you'll have to tell everyone to download it!
