Show clock after sending intent?

That's great!

I think at minimum having an app that started the voice assistant would be good - but as you say for it to be properly useful you'd want it with the pattern launcher.

I use a clock with 'Clock Info' and a Clock Info that sent the VOICE_COMMAND intent would be really handy. Then it'd just be 2 taps on the clock (1 to select, 1 to run).

Also worth adding that you could paste something like:

Bangle.on("tap", function(e) {
  if (e.dir=="front" && e.double) {
    Bluetooth.println("");
    Bluetooth.println(JSON.stringify({
      t:"intent", 
      target:"activity", 
      action:"android.intent.action.VOICE_COMMAND", 
      flags:["FLAG_ACTIVITY_NEW_TASK"]
    }));
  }
})

into the Custom Boot Code app so that just by tapping hard-ish on the watch screen twice (even with the watch locked) you can start voice commands
