MARC

iPhone app — currently for MARC.

What the app does

Live train tracking

Watch your train move on a live departure board, with a Live Activity that rides on your lock screen so you do not have to keep the app open.

Expected times from real history

Arrival estimates built from how this specific train has actually run recently — not just what the timetable promises.

Real reliability, not guesses

Every train and commute carries a track record built from continuously recorded trips, free to look up for anyone.
