Notes / Observations

  • Interactive demos sell better than screenshots. The coach demo showing a real calendar with workouts appearing is way more compelling than static images.
  • Early access gating lets us control rollout velocity and creates urgency. Waitlist → invite flow working smoothly.
  • Garmin error handling was a mess — now there's proper retry logic, classified errors, and server-driven recovery buttons. Users see actionable toasts instead of cryptic failures.
  • Mobile polish matters. Touch targets, keyboard avoidance, action sheets — the details add up.

Momentum Score: 8 / 10

Big landing page refresh shipped with interactive elements. Early access gate gives us control over the beta rollout. Garmin reliability got a major upgrade with retry logic and proper error surfacing. Mobile UX significantly improved. Good breadth across marketing, reliability, and polish.
