TomTom launch free sat-nav app
So what do you get with it? Well, it looks like it has more features than the competition, with live traffic updates and speed camera notifications and all that. Oh, and of course, you can navigate yourself with it. That's pretty obvious though.
You can also take trips to millions of 'points of interest' and if you're worried about hammering your data, you can download offline maps for the 111 countries covered by TomTom.
What's the catch? Well, it is free to download, but that's limited to 50 miles per month. If you're driving in advance of that, then you'll need to look at the £14.99 per year subscription (or £34.99 for three years).
Of course, you could just use Google Maps for free, or indeed, the Google-owned Waze which also won't cost you a penny.
However, Google Maps can be a bit of a faff, while TomTom Go Mobile has big, clutter-free buttons, which is advantageous if you're behind the wheel. Either way, sat-navs as we know them are rapidly becoming a thing of the past, so TomTom need to do something, and with this freemium model, they might be onto something.
Unless Google are scheming something...
