Zello Walkie Talkie

Almost a perfect product !

• No need phone number to use it (one to one) but if you want to create a group then you need to provide one !?
• can transfer images but nothing else !?
• voice chat is perfect and work fast, one people can talk and the other can lisen in live, you can even replay all the voice message after (the system keep them on their server if you are off line at that time

So a good piece of software too bad that it require a phone number for the group (i'll ask them why)

I've used it to 'virtually' accompany my girlfriend when she walks through shady neighborhoods. It does a good job at this. But Zello has to stay off most of the time for fear that someone will suddenly start telling the people around me things they didn't expect to know.

There needs to be some additional functionality around suppressing uninvited blurts, but at the same time, allowing someone with an urgent message to wake you up from your nap with their voice.

On Android, Zello also screws with bluetooth. My experience is that when Zello is running, sound from other apps doesn't reach my bluetooth headset.
