Add Runkeeper to the list of companies dropping their smartwatch apps -- albeit not for the usual reasons. The developer is warning customers that it's scrapping its Wear OS app as of the 9.13 release. It's "just not able" to deliver the best experience on Google's smartwatch platform, according to the notice. When a customer asked support for clarification, Runkeeper added that it was a "very buggy experience" and didn't work consistently well for most people. It's a "small team with limited resources," support added.
