Ari is your app for Zürich: a map that knows the city, and widgets you put together yourself. Made in Zürich by people who live here, with data from Switzerland. WHAT YOU CAN DO WITH ARI - See what's on today: concerts, parties, markets and exhibitions from several sources, on one map and sorted by day. - Eat well for under 20 francs: proper meals near you. - Find water, for your dog too: almost 1,000 drinking fountains in Zürich, sorted by distance, with a filter for fountains with a dog trough. - Discover queer Zürich, all year round: events, bars and community spaces. - Find the nicer way home: on foot through the old town, along the water and down quiet streets. - Plus weather and UV index, what to wear today, stops and departures, parking, city walks, places to unwind, gluten-free places, new places to eat and drink, sport, games and the moon phase. YOUR WALL, YOUR WIDGETS You decide what you see. Put your wall together: only the widgets that fit your day, in your order. New widgets are added all the time. WAYS THROUGH ZÜRICH You enter your destination, and Ari suggests routes and shows them on the map: sometimes the fast route, sometimes the quiet one, sometimes the better-lit one. FROM ZÜRICH We use Ari every day ourselves. The data is stored in Switzerland. We build Ari in the open, not once everything is finished, but together with you.
