We've already tested the best portable sat-navs, but you can get equally good turn-by-turn navigation on your smartphone with a dedicated app.
These software downloads remove the need to carry a separate device, and are ideal if you want directions in a hurry.
But with a bewildering amount on offer – from free apps to those costing £80 – which is right for you? We downloaded 12 apps to test on three different platforms.
Our preferred smartphone apps had offline maps – they take up more space on your mobile, but stop you having to download data on the move and relying on Internet access.
As in our sat-nav tests, we rated ease of use, accuracy and the time it took to reroute when we went wrong. We also looked at how well the app integrated with a phone’s features.
Apps that could navigate to a contact in a phone address book scored highly. So did those available for more than one operating system – Apple iOS, Android and Microsoft’s Windows Phone.
Live Premium from CoPilot proves you don’t need to spend a lot to get a good sat-nav app. We tried the £20 app on Windows Mobile, but it’s available for Apple and Android devices, too. The instructions are clear, the screen is easy to understand and it comes with a year’s free traffic info.
TomTom runs it a close second, while our pick of the free apps is Waze, as it’s available for Android and iOS phones.
