It's opt-in, and an early foundation we'll keep building on. • Search now includes your saved places, alongside visits, trips, and notes. • Better recording underground. In metros, subways, and tunnels where the phone loses GPS, Arc now recognises the situation and does a better job of following your actual route instead of stalling at the station entrance.
