i just installed zello on my cp. it's a ptt app that allows you to use your phone as a ptt walkie-talkie. just started using it today. great to be able to talk to another user without having to pay for call charges. this should be great for keeping in touch with your group when in the mall, on a hike or even when on different vehicles in a convoy.

- converts your phone to a ptt radio
- can talk to a single user on your list without the others hearing what you said
- can talk to a group that you can easily add from your list.

i have not tested the range yet. kasama ko sa work mga kausap ko and we are just maybe 200 meters apart.

search nyo.lang sa google "zello". note when setting up you need to at least allow voice recording to be able to transmit. all other permissions can be set to off (like your address book and pictures).
