Feedback - Snapshots
Because I've been viewing the Cronometer charts, and all of the data (and I'm involved in engineering/data every day), when I saw the "Snapshots" tab, I immediately thought "snapshots" was a point-in-time snapshot of the data (for instance so you could compare today's metrics to a month from now).
Yes, I know there's a camera there, and I get it, but a little UI thing might make it more obvious that it's looking for an actual picture of yourself. Perhaps "No pictures yet" instead of "No snaps yet", since the word snapshots has multiple meanings, might help a first-time user.
Again, may just be my frame of reference. And probably not a huge deal.
