This Week's Best iPhone Apps

Younicorn: Excusing the terrible portmanteau of a name, this app is wonderful: for adults, as a silly joke; for children who may actually believe in unicorns, as earnest dream fulfillment. Everyone is happy. Also: unihorned. $1.

This Week's Best iPhone Apps

Ratio: Cue Dan, resident culinaire/food terrorist:

Michael Ruhlman, cookbook author demigod and Gizmodo Food Week contributor, is bringing his excellent book Ratio: The Simple Codes Behind the Craft of Everyday Cooking to the App Store. Ratio takes sometimes-threatening elements of cooking like doughs, cakes, sauces, sausages, stocks and batters and breaks them down into more versatile ratios (bread is five parts flour to three parts water, for example). The app looks really great, actually: It has all 32 of the "critical ratios" in cooking, plus a calculator (to figure out exactly how much of everything you need), recipe ideas for each ratio, and ways to both store and share recipes (via Facebook and Twitter).

Fivebux.

This Week's Best iPhone Apps

Pastebot: You know how Microsoft Office's clipboard lets you keep track of everything you've copied and pasted on your PC? This is like that, for the iPhone. Except flashier, and with wireless syncing. Two dollars.

This Week's Best iPhone Apps

Battleship: This board game is such a good fit for the iPhone that it's amazing it took this long to show up in the App Store. Anyway, now it has, and it's quite good. The basic gameplay is pretty much exactly how you'd imagine it, but the extra gameplay modes—Salvo (multishot) and Superweapons (more than just torpedoes)—and the solid multiplayer implementations—Bluetooth, Wi-Fi and and pass-off—are what make it worth the price. $3.

This Week's Best iPhone Apps

Bing: Sitting proudly in that small sliver of the venn diagram of non-Google-users and iPhone owners, the Bing iPhone app does exactly what it claims it will do, for free: It Bings. And it Bings quite well! Maps are included too, if you're tired of the stock nav app.

Type n Walk: Says Adam:

Texting while walking is dangerous, as you can't see what's in front of you. The Type n Walk iPhone app, as predicted on April 1st, solves that by using the camera to make the phone transparent. Sigh.

But it saves lives, man! $1.

This Week's Best iPhone Apps

Gunman: Not the first augmented reality gun app, and not the cheapest. But I will give it credit for being the first to actually work like a game: once players have connected over Wi-Fi and entered their opponent's shirt color, Gunman analyzes shots from the iPhone's camera, taken when the "fire" button is pressed and decides whether or not you've killed your adversary. It's like a real-life FPS—or at least it would be, if the whole process was a little faster slow. The rare occasion where a concept is wonderful enough to trump iffy execution. $3.

This Week's Best iPhone Apps

Dragon Search: Dragon's fantastic speech recognition app was fun to play with, but in order to use it with anything you had to copy text, close the app, open another app, paste it in, and so on. Dragon search jumps straight to a browser. It's a lot like Google's voice search app, but the recognition engine is stellar.

This Week's Best iPhone Apps

Need for Speed: Shift: There are plenty of tilt'n'race iPhone racing games, but this is easily the most impressive to date; the graphics rank among the best I've seen on the iPhone. The wide camera angle and automatic accelerating/tap-to-brake control scheme can make racing feel a bit like you're falling into the track rather then driving through it, but it's not unpleasant or irritating—just a little odd. All that said, $10 feels a bit steep.

This Week's Best iPhone Apps

TikiNotes: Less a notes app than a platform for one of those wacky alternative keyboards, TikiNotes is proud of its learning curve. If you buy into its claims, the keyboard should make one-handed typing much easier and faster, but I honestly didn't have the patience to prove them right (or wrong). That's up to you, QWERTY malcontents: the app is free, so get to it.
