Thanks to instructions posted here: http://roundandroidwatches.proboards.com/thread/1369/android-wear-apps-work-tygryst I was able to convert some Android Wear apps to work on the Amazfit Pace. You will also find a dozen or so apps on that site as well. (Registration required for access)
Seems to be kind of hit or miss as to whether or not an app will work. So far as I can tell, if the Android Wear app requires communication back to the phone (eg: Spotify, Calendar, etc) it’s not going to work. But apparently, some apps are using an out of date framework that doesn’t work on Amazfit Pace regardless.
Here are the ones I converted. I take no credit for these – they’re all the work of their respective developers.
