What? Almost none of those features require costs to maintain:

- Car Ride Mode - adds extra bounces

- Level Lock - don't change rhythm

- Sleepytime Sounds - play sounds before and after sleep

and so on.

The only ones I can see? Tracking, Sleep Logs (but I'd also argue that given that this is a smart device, I'd say that they could be expected baselines).

But as for the other, without being argumentative, I am sincerely struggling why it seems reasonable to you that "extra bounces", etc. are a Premium "subscription" feature.
