See the traffic around you and ahead of you at the same time with two maps with live traffic, each with its own zoom level. Traffic Maps is designed to give you a quick view of traffic conditions while driving. Keep one map zoomed in on your surroundings and the other zoomed out to see traffic conditions further ahead. See that your usual highway exit is congested? Spot a traffic jam ahead? If you know the area, a quick glance may be all you need to choose a better route. TWO MAPS, ONE TRAFFIC VIEW - Follow your position on two maps simultaneously - Set a different zoom level for each map - Adjust the relative size of the maps, or use a single map - Choose between north-up and driving-direction views - Customize how the maps follow and center on your position - Your preferred map configuration is remembered for the next drive NAVIGATION AND CARPLAY Go beyond traffic monitoring with a complete set of driving and navigation features: - CARPLAY Use the dual-map live traffic view directly in CarPlay and navigate with turn-by-turn directions and lane guidance. Navigation information can also appear in the instrument cluster on compatible vehicles. - TURN-BY-TURN NAVIGATION Navigate on iPhone and CarPlay with clear driving instructions, lane guidance, speed limits and live traffic information. - PLAN AND PREVIEW ROUTES Create routes with intermediate destinations before you leave. Preview the route together with speed limits along the way. - RECORD YOUR TRIPS Record your journeys whether you are navigating or simply driving, and review your route and your speed throughout the journey. - APPLE WATCH Follow navigation instructions from your wrist, including upcoming manoeuvres and lane guidance. - SHORTCUTS AUTOMATION Use the app with Shortcuts to automate your driving routines. Open the app in CarPlay, start routes and automate other actions. - NO ADS Use all the available screen space for useful traffic and driving information without advertising interruptions. Traffic Maps can be used for free to view live traffic on two maps that follow your position as you drive. Traffic Maps Pro is available as an optional subscription and unlocks navigation, CarPlay, route planning and recording, Apple Watch integration, advanced Shortcuts support and an ad-free experience. Whether you already know the roads and simply want a better view of the traffic, or you need turn-by-turn navigation to your destination, Traffic Maps gives you the information you need while you drive. Continued use of GPS running in the background can significantly reduce battery life.
