Android/OS X: Apple’s Messages app on a Mac is a neat way to chat with your iPhone without having to pick up your phone. However, it doesn’t work if you have an Android device. Until now. SMS Integration for iChat allows you to send and receive text messages from an Android phone via Messages.
The app runs on your phone and relays your text messages to the Messages app on a Mac. The service gives you a free five messages per day, though if you want to exceed that, it costs $12.99 per year. While that seems steep for six messages, presumably the price tag is more targeted for people who will be texting all the time. If you’re always picking up your Android phone while sitting at a Mac, and you like Apple’s Messages app, this is a nice compromise.
