Getting home at night is a chain of small uncertainties. Sharing live location all the time is noisy; doing nothing is worse.

Built a local-first app that stays silent while a trip is on track and alerts a contact only when a check-in is missed.

  1. Shaped a five-step flow across six transport modes, with day/night safety scoring, route comparison, checkpoints, and live trip state.
  2. A route is only as safe as its weakest stretch: the score weights the minimum area above the average.
  3. Extended a v0-generated base into a complete demo with no backend; the whole flow runs on local data.

A complete solo prototype with a working contact view and no server to depend on.
