Ping wasn't the only Apple service to go offline at the tail end of September. Chomp, an app search engine purchased by Cook and Co. earlier this year, also closed up shop. In the spring, the service discontinued support for Android apps, and now its entire website and iOS application have been shuttered. Folks who still have the app installed are greeted with the bad news upon launching it: "Chomp has been discontinued as of September 30. Thanks for being a loyal user." If you're mourning the loss, we hear Yahoo would be delighted to make your acquaintance.
