This entry-level sat nav has plenty going for it. It's easy to use, the screen looks great, and it has a good range of features. It can't plan routes far in advance as some models can, but if that's not an issue for you, this model is a worthy pick.

This is one of our top-performing sat nav apps. The map is clear and easy to read, and it’s great at getting you smoothly through towns. It’s free to download, but you’ll need to buy maps after the seven-day trial to use it.

It may be free, and can calculate routes reasonably quickly, but this app for Apple devices has little going for it other than that. The map and audio instructions can sometimes be difficult to follow, and you'll have to pay extra for speed camera and live traffic information.

Should I buy a sat nav or use my phone?

We put every sat nav and sat nav app through the same series of tough tests using a GPS simulator. And we’ve found some great sat nav apps in our tests, including apps that are good enough to be Best Buys.

A sat nav app is installed on your smartphone. They tend to be cheaper than dedicated devices but might not offer quite the same quality of user experience. Handily, it’s easy to download an app, try it and then delete it if you're not satisfied. Many will include or have the option to add useful features.

We have tested sat nav apps that offer good-quality navigation to rival a dedicated device, but we’ve also found others that have such poor guidance we simply wouldn’t recommend them. If you’re unsure whether you need a standalone sat nav or a sat nav app, try our interactive tool and find out how to buy the best sat nav for you.
