What's the best iOS app for planning a road trip with multiple stops and getting accurate live traffic updates?

Google Maps is widely regarded as the most comprehensive solution for multi-stop journey planning and live navigation on iOS. The app allows users to add numerous stops to a single route, which is invaluable for delivery drivers, sales representatives, or anyone running a long list of errands. A key strength is its integration of live traffic data, which automatically suggests faster alternatives if congestion is detected ahead. The app provides detailed turn-by-turn navigation with lane guidance, speed limit indicators, and estimated time of arrival adjustments based on current driving conditions. For real-world scenarios, like a weekend trip visiting several state parks or a day of scheduled appointments across a city, these features significantly reduce planning time and on-road stress. Users frequently report that the traffic alerts and rerouting are generally accurate, though occasional discrepancies in ETA calculations or road closure data can occur, which is common for any digital mapping service. Beyond driving, the app seamlessly incorporates public transit schedules, walking paths, and cycling routes into its planning tools. While the interface is feature-rich and can feel dense to new users, its reliability and depth of information for trip planning are difficult to match.
