The same live board, map, and pin-anywhere setup — from a free download to a finished wall unit. Everything shares one engine, so features land everywhere at once.

Get it & the sourceWhat’s shared vs. what’s unique
Build the engine once; each product is a thin layer on top.
Shared everywhere
Live arrivals, walk-time filtering, the learned reliability ratings, the “leave now” advice, pin-anywhere discovery, and the stop-by-stop map — one engine, identical across web and iPad.
Wall display (web · iPad)
Landscape, touch-free, auto-rotating between the board and the live map. Designed to be glanced at from across a room.
iPhone, made mobile
A native touch app: tabs, search any stop, saved boards, a trip planner, and widgets — the one version that leans into being handheld.
What you get when you upgrade
The board, the map, and the on-device smarts are free and open. Pro and the hardware add the things a single free copy can’t do on its own.
