I need a chat client that works over the web and Android and iPhone so that users on all three platforms can chat
No advance features are required- just the basic functionality of chatting and maybe the ability of users to set their names and see who else is online.
If you cannot do this within the specified budget please don't bother bidding
If your bid is going to say "Please see PMB" then you also needn't bother bidding
Apart from that, happy bidding :)
