The last one I do all the time at the gym. You can say start an indoor run and it pops up, you can also say open workout and it opens the app. Any specific workout you can start. This is while my phone stays in the locker room with no wifi since my gym oddly doesn't have wifi.Just couple of things I would like to see in future watch OS:
1. Native sleep tracking app.
2. Auto detect workout (start with the basics i.e. walking, running and swimming etc.).
3. Always on display for time only while the rest of the complications will show up when either raise the hand or tap on the watch screen.
4. Siri independent of the phone e.g. ask siri to open workout app or start an outdoor walk/run. Is this even possible?
