If you’re heading out to meet someone, there are plenty of ways to inform them of your location and estimated arrival. Chat apps like WhatsApp, Messenger, LINE, and iMessage, for example, offer location sharing functionality, while navigation apps like Waze and CityMapper and even ride-sharing apps like Uber offer live updating ETAs. Now, Google Maps’ own ETA feature is at last coming to iOS. The feature also getting a few tweaks following last year’s launch on Android, the company says.

In May 2017, Google Maps first introduced its own take on location and ETA sharing.
