How did you think for example notifications were pushed to Bluetooth smart watches?

[esrauch]

I would have assumed there is an os notifications api, and the apps have no idea what surface the notification will be shown on.

You are assuming they were aware of that capability.

Not OP: I have a fit band but it only gets notifications if Bluetooth is on. I'd be (ie, I am) surprised to find you couldn't turn Bluetooth off and that they purposefully provide a switch that doesn't work so they can fool you to thinking you can turn it off.

Presumably only Android works like this?
