Clutch.io is a service that allows iOS and mobile developers to easily and quickly do app testing, which helps them track just how customers use their apps. The service has been helpful in the past for a number of app developers and their products, but Clutch has now flipped over to just one client: The company has been acquired by Twitter. Clutch says it will work on the same type of work at Twitter, aiming to grow the company on a worldwide scale.
As for developers using Clutch now, there's both good and bad news. The bad news is that the service is getting shut down -- it will be supported until November 1, and after that Clutch's servers will no longer work. But the good news is that Clutch is basically open sourcing the whole thing. The company says it will release all of the necessary documentation and software for devs to continue to run the testing service on their own servers. And any currently running tests are designed to "fail gracefully" should Clutch's servers go down, so there shouldn't be any issues with end users at all.
All in all, it sounds like a good move for Clutch, and that developers who might be affected will at least have a way to deal with that. As for us Twitter users, I'm curious to see how this affects Twitter's mobile experience going forward. Twitter's one of my most-used services, so anything that makes it even better sounds good to me.
