The clock app in iOS 7 is pretty straightforward. There’s an alarm, stopwatch, timer, and a world clock. The latter allows you to add any number of cities to your list and your iOS device will tell you the time in each city. You can rearrange them into any order you like with a quick tap on the Edit button in the upper left. To add new cities, simply tap the plus button in the upper right.

The world clock defaults to an analog representation of the time to the right of each city. We can fix that.

It’s hard to see why the folks at Barcelona-based Honest&Smile built this crazy contraption into a Moleskine notebook, but that doesn’t make it any less neat — after all, Doc Brown built a time machine into a DeLorean. When closed, it looks like any other overpriced book of blank paper. When opened, it reveals a kind of analog Instagram playground.

I love gaming on my iPad, but for certain titles, virtual controls just don’t cut it. First-person shooters, fast-paced platforms, and even sports simulators are much better with physical controls. And there are plenty of them for iOS devices, but the Audojo for iPad could be the most convenient.

It’s a case with built-in analog sticks and triggers that turns your iPad into a real handheld gaming machine. But there is one thing missing.

Realmac Software, the developers behind Clear and RapidWeaver, have slashed the price of their Mac apps by up to 65% for the holidays. All of their titles are included in the sale, which lasts until January 6, and Clear for iPhone has also been reduced to just $0.99. We’ve got a complete list of the apps on sale below.

At one time, deep back in the swirling mists of time, Polaroid was like the Apple of photography, not only making the best stuff but also inventing new ways to do things. Now, the brand is nothing but a label slapped onto a bunch of crap by the current owner.

But that doesn’t mean that there’s nothing amazing going on in the analog instant film world. Take a look at the Impossible Project’s FPU (Film Processing Unit), an amazing gadget that marries your iPhone to real, instant analog photos.

The Fling controller from TenOne Design (soon to be reviewed) is a great way to add a physical to your iPhone or iPad, just by suction-cupping it onto the screen. This means that it works with any game on your iOS device that uses an on-screen “joystick.”

The downside is that it moves at the worst moments: I have wiped out in more than one GTA car chase this way. But designers at the Keio University in Japan have come up with another idea. A joystick which uses the iPhone’s camera as a controller.
