Needs you

When a call is yours, it reaches your wrist — short, named, with its reach and undo. Ship it, ask for different, or dismiss.

01Main view

The overview you understand.

Your North Star, the drivers under it, and what the team shipped — one screen, written in sentences a non-engineer reads at a glance.

  • ⌘K to anywhere — apps, proposals, versions
  • Scorecard live in the chrome, not buried in a tab
  • Every line expands: sentence → evidence → full diff

Read a line. See the proof.

First-person and plain: “I noticed checkout dipping, tested three fixes, shipped the one that held.” Click for the evidence behind every claim.

  • Threaded by app, proposal, and version — never raw logs
  • Click → evidence: the real diff and the real numbers
  • Click → undo: put any version back in one move

03The decision

What reaches your wrist.

Short. Named. Carrying its claim, its reach, and its undo — not a backlog. Three lines of text, no scrolling, one decision.

  • Ship it · ask for different · dismiss
  • Ranked by what only you can decide
  • Wrist-shaped: three lines, no scroll, one tap
