11. Google Maps (free)
Google's data was also ousted from iOS 6, with Apple instead using its own data, with - to be charitable - decidedly mixed results. This free app is a better bet; it's fast and beautifully designed, and the iPhone 5's bigger screen is handy for browsing and also checking out step-by-step directions. On the move, turn-by-turn on 3G also proves effective.
12. Fantastical (£2.99/$4.99)
Apple's own Calendar app is fine, but Fantastical has two advantages: excellent natural input for events, and an emphasis on a list view, thereby making it easier to see upcoming appointments at a glance. Naturally, the iPhone 5 means being able to view more of these at once, which is fab (unless any of said events mention 'dentist').
13. Soulver (£1.99/$2.99)
With lots of people banging on about skeuomorphism in apps, it's perhaps surprising more products like Soulver don't exist. It rethinks and reinvents the calculator, making it relevant for modern computing, and the result is half spreadsheet, half 'back of an envelope'.
On the iPhone 4, it feels cramped, but on the iPhone 5 there's plenty of room for its line-based calculations.
14. 30/30 (free)
Task managers are commonplace on iOS, but we have a real sweet spot for 30/30. It's beautifully designed, and the straightforward manner in which you can set up task loops makes it perfect for Pomodoro-style time management. IAPs provide extra icons or a thank-you to the author, and the iPhone 5 screen really shows off the sleek interface.
15. Dropbox (free)
Apple's vision of the future is files existing within apps, which is fine if you only use few apps with few documents. For the rest of us, a file system is still required and Dropbox brings this to iOS. On the iPhone 5, the taller screen enables you to see more items at once, but even if Sir Jony Ive had given the device a two-inch square screen, we'd still be recommending Dropbox.
16. Infinity Blade II (£4.99/$6.99)
Swipey swordplay with RPG levelling up is what Infinity Blade II is all about. The visuals are gorgeous and the iPhone 5's full resolution is supported. Given the demanding nature of the app, you'll be grateful for that A6 chip, too.
17. Need for Speed Most Wanted (£2.99/$4.99)
The best arcade racer for iOS, Most Wanted is a stupid amount of fun as you speed about, smashing up cops, drifting for miles, and generally being a menace on wheels.
On slower hardware, though, dropped frames periodically pull you out of the experience; no such problems on the more powerful iPhone 5.
18. Super Hexagon (£1.99/$2.99)
The perfect twitch arcade experience, Super Hexagon is a bit like playing a wire loop game in fast-forward while being flung about the place on a merry-go-round.
Although visually simple, the game is far more fluid on the iPhone 5 than other iOS devices, and the widescreen display keeps your thumbs out of the way as you wrench your tiny ship left and right, avoiding infinite walls of doom.
19. Beyond Ynth (£1.49/$1.99)
iOS isn't what comes to mind when you think of platform games, and virtual controls often make us shudder, but Beyond Ynth bucks trends by being brilliant at both.
This puzzler/platformer is all about helping a bug traverse 2D levels. Its method of travel: increasingly complex boxes. On the iPhone 5, the game looks lovely, your thumbs cover less of the screen, and you see a fraction more of what's coming.
20. The Room Pocket (free)
The most atmospheric iPad game of recent times loses little in its translation to the widescreen iPhone 5. The demanding graphics means The Room's perfectly suited to Apple's newest smartphone, and the game is a masterpiece.
You're alone in a room with a strange box, left to become immersed in a creepy, frequently chilling few hours of discovery. Our advice: avoid the hints, wear headphones and play in a dark room. Just don't blame us when you leap out of your seat.
