With so many different kart pieces to unlock in Mario Kart 7, it can be tough knowing what's what and how to maximise your kart's abilities for land, sea and air. That's where the Combo Explorer app for iOS and Android can come in handy.
The application lets you create a custom kart from all in-game parts and see how it stacks up against another configuration, with hidden stats giving you the full picture on your chosen chariot. You can 'lock' certain characteristics, letting you tweak a ride around your favourite character or glider and see how its statistics change accordingly.
It's a nifty little app that could shave seconds off your best times or give you the all-important advantage in online play. Keen MK7 players with an iOS or Android device might want to check it out at Combo Explorer.
