The best smartphone app
There’s a raft of apps to make drivers’ lives easier. We name two we can’t live without
Can I use a phone app in-car? And won’t apps zap my battery? The law states it’s illegal to touch a handheld telephone with the engine switched on. But once you’ve set them up, most in-car apps are designed to run while you drive – although a phone holder is an essential so you can see the screen while on the move. Some apps do use more battery than others, though – it’s wise to get a 12-volt car charger for your smartphone.
What about data usage? Will apps leave me with a big bill? And will they reveal my location? Some apps use more data than others; what this costs you depends on your phone contract. But many don’t eat into your data at all; these often take up lots of phone memory. Just bear in mind that data usage is expensive when abroad. Many apps rely on anonymous location data; they won’t reveal personal details without your permission.
