Not at the moment.
We'd like to support as many devices as we can. But currently we have limited engineering resources and we want to get it right for iOS and Android devices. Once that is done, we will see what we can do to expand Wishbone support.
We are working on iOS 8 HealthKit integration at the moment.
Please note that HealthKit is currently designed to track one person (usually owner) health status while Wishbone is meant to monitor multiple users' temperature data. So we need to find a way to share the right profile's data.
