Whisper for iPhone is a new messaging service that takes advantage of the App.net API in order to bring super fast messages over any network complete with push notifications. For times when services like iMessage and regular SMS messaging fail, it's always good to have a backup, and Whisper is a super exceptional one that's packed with useful features.
If you use ADN on a regular basis, you're probably already aware that one of the coolest parts is that they encourage developers to build amazing apps based on the service, which is pretty much the opposite of Twitter's take on third party clients these days. Not only can you text message over any internet connection like you can with iMessage, but it supports discrete photo and location sharing, stickers, and more. The location sharing portion of Whisper makes it easy to give directions either by walking or driving to a friend without having to leave the app or copy and paste address information.
iMessage can be a bag of hurt at times with messages hanging up or not sending over Apple's servers. With apps like Whisper available now and BBM coming this summer for both iPhone and Android, Apple's got their work cut out for them if they'd like to keep people hooked on iMessage. Particularly when it comes to stability and feature set. A lot of us here at iMore are hoping for some iMessage updates in iOS 7. We should find out on Monday whether or not that'll be happening.
In the mean time, if you're traveling to WWDC this year, it probably isn't a bad idea to have a backup plan for when communications go down in flames. It's not a matter of if, but more like when as anyone who has ever attended in the past painfully knows. Whisper makes a great alternative if you and your colleagues have ADN. The best part? It's fast, and it's free.
