Interval Devices And Sensors
A sparse settings screen for the hardware a heart rate reading comes from: three paired devices as hairline rows with a battery figure derived from hours rather than typed, a real heart rate source preference, and one computed note on why the wrist and the chest strap file the same hard minute in different zones.
Paste into Claude Code, Cursor or Windsurf. It builds this screen 1:1 in your app.

The rule this design follows
It ships exactly as previewed: same colors, same type, same copy, same motion. The prompt tells your agent to build that, and not to adapt it to your existing theme.
