The transit display that tells you when to leave
Know exactly
when to leave.
Shows only the buses you can actually catch — and tells you the moment to walk out the door.

How it thinks
Anyone can show a countdown. This one tells you what to do with it.
Drop a pin, not a stop code.
Drag it to any corner, or tap “use my location.” It finds the nearest stops and every line that serves them, in both directions.
It learns which buses to trust.
Predictions drift and ghost buses vanish. It watches how each line actually performs — so “4 minutes” means four minutes, not a guess.
One line tells you what to do.
Walk time plus the live prediction, distilled to a single call: leave now, or in three minutes. No mental math at the door.

Try it nowWhat it does
Built to look right and behave like the real thing.
Stop-by-stop live map
Rotate to a clean map where every line has its own color, stops are marked, and each bus advances stop by stop along its route.
Articulated-bus indicator
A single walking figure marks a standard bus; two figures mean a longer articulated bus is coming.
Works anywhere by coordinates
Not tied to one neighborhood — set any location by pin or device geolocation and it re-centers.
Respects the API rate limit
A built-in budget batches requests and backs off automatically, so it stays within the data provider's limits.
Reduced-motion friendly
Honors your system's reduced-motion setting, easing the carousel and transitions when you ask it to.
No API key to hunt for
On the paid and hardware tiers, live data is handled for you — no token to request, paste, or manage.
Run a building, gym, or office?
Put a branded next-departures board in your lobby — an amenity residents and members actually use.
