Waze
Free and available on Android and iOS
Part navigation app, part social network, and part geo game.
Waze relies on its users' data to constantly evolve and improve, and the results have a hugely positive response from the Waze community.
Luckily, with a community of 190 million monthly active users, it has plenty of information and data to fuel its journey.
Essentially, the app is constantly learning.
The more people use it, the more real-time information is fed back in, so active users get updates on traffic, estimated arrival times, and any police presence such as speed cameras.
If you use Waze on your daily commute, it will learn from your routine and pre-empt any anomalies, ensuring that your journey home is as hassle-free as possible, despite any unforeseen roadblocks.
But it doesn't stop at helpful traffic updates.
Users can update and suggest service stations and points of interest along any route and flag petrol stations by price too.
Drivers travelling to the same destination in separate vehicles can even keep tabs on everyone in their party to ensure no one takes a wrong turn or gets left in the dust.
The developers have even pre-empted any hesitation in allowing data sharing by incentivising users with geo-gaming features and the ability to develop a personal avatar.
