I've been thinking about this quite a bit, and though the DropBox is mentioned briefly, I'd really like to understand more about why we're comfortable with paying a subscription to them, but not other similar apps.

I think we're similar to Whoop in this way. Any Whoop users want to chime in about how they feel about the subscription model?
