MapKit is a software library that allows you to use Yandex map data and geo technologies in mobile apps
Use MapKit to create an app with Yandex maps for iOS and Android. Your app will be able to search for businesses and place names, plan driving and walking routes with current traffic conditions, and show traffic and panoramas on the map.
The map that you create using MapKit will stay current to show new construction, new roads and interchanges, and recently opened businesses. In short, all the changes that are made on Yandex.Maps will also appear in your app.
