Navigation apps always need to be updated, just like every other software, to keep the information and data as recent and efficient as possible. But, each developer will release updates and patches at different times and different frequencies. However, to use as an example, let’s take a look at an ultra-popular GPS application Google Maps. Now, Google does not actually release the frequency in which they produce updates but research has shown that it does shift depending on where you are in the world.
In the United States, they generally release an update once every two weeks. But in other places around the globe, they may only release an update once a year. However, The Google Earth Blog made it a little clearer. According to the blog, the more populated a location is the more frequently Google will release updates for it. This would make cities such as Los Angeles and New York prime candidates for weekly updates. Meanwhile, rural areas may have to wait for months for a new update. As an algorithm, it makes perfect sense.
