Goal

The navigation screen.

Acceptance criteria

  • Turn arrow dominates the screen
  • Distance to the turn counts down smoothly and is legible at a glance
  • Street name shown when the backend supplied one, gracefully absent otherwise
  • Small then-turn indicator for the cue after next
  • Remaining distance and ETA on a secondary row
  • Clear off-route state replacing the arrow
  • Distinct route-complete state

Files

  • watchapp/src/c/view_nav.h

Update — 2026-09-02: view_nav has two modes

  • On route: the existing turn arrow, countdown, street, then-turn and ETA
  • Off route: a bearing arrow to the rejoin point and the distance to it, from
    NAV_REJOIN_BEARING / NAV_REJOIN_M (D42)
  • The two modes are visibly different at a glance — an off-route rider must not mistake the
    bearing arrow for a turn instruction
  • Bearing arrow rotates with the rider's heading, since the bearing is heading-relative
