I love the daily emails - LOVE them. The layout is harsh from a design and conceptualization perspective.

What I’d enjoy is making them more visually pleasing and easier to grok (Lower variability good, unless the previous day was a fasting day). So reducing that down to visualization that always fits well on my phone email would be awesome.

Or maybe spike time expressed as a percentage of the day and how it’s performed relative to my “normal” or others normals would be really informative.

A design goal could be removing the “which direction is ‘good vs bad’ thinking” from the equation.

If you take each piece of information on that page and reduce it to a set of sparklines, that page instantly cleans up and becomes an adaptive layout for different size screens. And then you can start to view packaging of each piece of information more effectively and iterating on them.

It would be cool to offer design options as an “opt-in beta” to allow people to actively participate and provide feedback.
