Yes we have BBM for Blackberry users, and soon iMessage for new iOS users. We have had client for cross platform messaging like the famous WhatsApp on all famous platforms. This time it is something similar called Ping Chat. It allows users to send unlimited text and picture messages, voice notes and do group conversations. Sharing social profiles with contacts is another added feature of this app.
Registration process is unique in a sense that it allows you to register for a Ping Chat ID! Of course, people might have difficulty finding you because of the random id. Anyhow, it can quickly go through your contact list and add the ones using Ping Chat in your list. Contact organization is well planned with adding contacts from Facebook, Twitter contacts easier. Its more efficient, easier to use and well designed cross messaging platform.
