To the North Pole. Into the heart of the Amazon. Or all the way to Mars. Your next adventure starts outside your door. ExoWorld connects real walks with virtual expeditions. Find a new route, head outside and turn the kilometers you walk into a journey toward an extraordinary destination. It is not just about how far you have walked. It is about where your steps can take you. EXPEDITIONS THAT GET YOU OUTSIDE North Pole — beyond the everyday An icy landscape lies ahead, with a destination you will reach through your own determination. Every eligible walk takes you further across the polar ice. You do not have to reach the pole today. Just get closer than you were yesterday. Olympus Mons — your walks, your Mars Set out on a 600 km journey to the foot of Olympus Mons on Mars and take on the challenge of 21,900 meters of accumulated ascent. Distance brings you closer to the mountain; the elevation you gain on your walks takes you toward the summit. Even that familiar hill near home takes on a whole new meaning. The Amazon — into the green unknown Step into a world of rainforest stories and brisk walking challenges. Here, it is not just about kilometers — some sections call for a quicker pace. Start each challenge yourself, when you are ready. You walk your real route while your expedition moves through the Amazon rainforest. Choose an active expedition and let your next walks count toward it. Individual walks come to an end. The bigger adventure continues. DISCOVER A WORLD WITHIN REACH Find walks, stories and places worth stopping for. Take a different route and watch the fog lift from the map where you actually walk. You uncover it with your own steps, not a tap on the screen. YOUR JOURNEY DESERVES ITS OWN STORY Record your route, add photos and save the stops you do not want to forget. Share your walk with others or keep it just for yourself. Need to pause your outing? Your progress stays saved so you can carry on later. A MEMORY YOU CAN HOLD Completing an expedition unlocks the option to buy its commemorative coin. Not just another number in an app, but a tangible reminder of a journey you completed with your own steps. Commemorative coins are purchased separately. They are not included in a subscription or automatically awarded for free. Choose today's walk. Find your next big destination. ExoWorld. Every great expedition starts with a first step. An account is required to use the app. Some features require location access, internet or an ExoWorld+ subscription. Connecting to Apple Health is optional.
