What's the best iOS app for planning and paying for public transport trips in and around Paris?

Île is the official companion app for navigating the Paris region's extensive public transport system. For visitors and residents alike, it consolidates essential functions into a single interface, eliminating the need to juggle multiple resources. The app excels at journey planning, offering detailed itineraries that combine the Metro, RER trains, buses, and trams. It provides real-time service alerts, departure times, and disruption information, which is critical for navigating a complex network. A key feature is the integrated mobile wallet, allowing users to purchase and store digital tickets and passes directly on their device, reducing reliance on physical tickets or separate card readers. While the core navigation is robust, some users note that the interface can feel slightly cluttered during initial use. Furthermore, while ticket purchasing is streamlined, the process requires a stable internet connection at the point of transaction. For anyone needing a reliable, all-in-one tool for getting around Paris—from calculating the fastest route to having a valid ticket ready for inspection—this app serves as a dependable daily utility.
