Waze is not like many other navigation apps, as it relies on the input of its users to guide people from A to B. Thankfully, it’s proved to be exceptionally popular and so you can rely on a huge community, which is arguably more reliable than using satellites — the method most navigation apps have to use.
You will be offered the best routes and will be continually updated with the current traffic conditions, and the social aspect of the service feels pretty unique. The more you put in to the service, the more you’ll get out, and you are rewarded for making an effort. This is why the service works so effectively and why Google felt the need to get involved in the project. It works best with friends because you can see where they are and vice versa, and even the maps are continually updated by an army of people who are looking for changes in roads and events all of the time.
Waze may feel too friendly to be taken seriously at first glance, with all the smiley-face cars, but the service works well. Definitely worth a try.
