Starting a recording session from the apple watch would be useful. So when I start a workout on my apple watch and I can also prompt the ring to record as well. Many watch wearables may not record all of what Oura can collect (for example my watch does not record SpO2). Recording this data by prompting Oura to actively track until the activity is completed would be very useful. Sure, active tracking of some data will put a drain on the battery momentarily, but that's up to the user if they want to be actively recording HR, SpO2, etc during a certain session and being able to start a session besides in the main app would be useful, especially on the apple watch app.
