Apple Maps vs Google Maps
Apple Maps and Google Maps are two of the most well-known sat nav apps, and many people will have put the navigation skills of one or both of them to the test. Neither is perfect, nor as good as the very best sat navs we've tested, but they're free and come as standard on Android phones or iPhones, so are incredibly popular.
If you're buying a smartphone and the built-in mapping is a major consideration, it's worth knowing that although Google Maps is available as a download for iPhones, Apple Maps can only be used on an iPhone. Both have their pros and cons, so read on to find out which sounds right for you.
A key consideration when picking any sat nav app is whether it is compatible with your smartphone, and this is the most notable difference between the apps offered by Apple and Google. As mentioned above, Google Maps can be used with both Android and iOS, so whether you’ve got an LG or Samsung or other brand's Android smartphone, or an iPhone, you have the option of using it. Apple Maps can only be used on iOS devices, so it’s limited to iPhones or iPads.
There are plenty of free sat nav apps around, and Google Maps and Apple Maps are no exception. Both are free to download and use.

If you’re a regular driver, the quality of the guidance will be the most important factor. But you’ll also want an app with traffic information to help you traffic jams. Both the Google and Apple sat nav apps display traffic data for free, but you will need a constant mobile data connection on your smartphone to make the most of it.
The majority of sat navs and sat nav apps come with at least some maps at no extra cost, and the Apple and Google sat nav apps both offer worldwide maps for free. Not all sat navs or sat nav apps come with free map updates though, meaning you could be left wondering where that new roundabout came from, and which exit you should take. That’s not a problem with Google Maps or Apple Maps – both have automatic map updates, and you won’t have to pay any extra.
Using Google Maps, you can download a part of a map so that you can access it offline – useful if you have a mobile data allowance cap or suspect you’re heading to an area with poor signal. These downloads are size limited, with a maximum download size for each of 1.5GB, but you can download as many areas of a map as your phone’s storage will allow.
With Apple Maps a part of the map is downloaded after a route is calculated, but other than that you can’t download the maps.
One of the great things about a sat nav app is the convenience of using it on the go – perfect if you take a wrong turn or meet an unexpected diversion. However, this can have an impact on your mobile data usage. Our tests have revealed dramatic differences in how much data different apps use, with the worst using a whopping 5MB and the best using only a few kilobytes.
