Google continues to be the dominant force in the map online space. Despite recent setbacks with their partially crowdsourcing Maps, Google Maps team announced the renewal application for Android Wear and adding new API for Wear-developers.
This is much more convenient, because for land navigation is easier to use a wristwatch instead of keeping to a smartphone or tablet. It is also important to note that the clock still must be connected to your main unit.
Google also announced a new API for Android Wear-development that will integrate Google Maps into their programs. At the start of API available only to large companies, but soon an opportunity to introduce Maps will be available to everyone.
