IM+ is one of the top-rated Instant messaging clients in the iOS app store. It has universal device support, and a list of features that'll suit any messaging fan. Shape Services, the company behind IM +, is constantly improving its iOS app. The latest update landed today and includes Beep, a new IM+-specific messaging service.
Beep will let you send instant messages to other friends and family who are running IM +. You can compare it to RIM's BlackBerry Messenger service, which lets Blackberry users message each other. The IM+ version is better than BBM because it has more features and is available on Android, iOS, BlackBerry and Windows Phone. I was able to evaluate the latest version of the IM+ app and check out Beep on both an iPhone 4S and a Galaxy Nexus
