Moves is that rare thing on the modern App Store — a free app that has an enormous amount to offer. It’s magical in its simplicity, an app that asks no more than you switch it on and forget about it.

All you have to do is carry on with life. Moves tracks your movements, intelligently works out whether you’ve been walking, running, cycling or using transport of some kind, and provides you with a helpful summary at the end of each and every day.

Best of all, though, it does so without any need for input from you. You don’t have to tell it that you’re going out for a run. You don’t have to tell it you’re walking from A to B.

It just knows.

New interface ideas are few and far between on the App Store these days, but productivity app Sooner is crammed full of them. It’s also elegant and speedy and rather fun to use.

FioWriter is a text editor for iOS, outwardly similar to many that have gone before it, but with a style all of its own. One important difference is that it provides keyboard shortcuts of the sort you’re familiar with on your desktop computer. Their usefulness, however, depends on the device you’re typing on.

Hey! Hi there! Grab a chair, pull it closer to the fire. It’s cold outside isn’t it? And you look like you could do with thawing out.

Yes, it’s a lovely fire, isn’t it? Feel free to add some more fuel – anything you like. Your chair, for example. Or your aunt. Or yourself. This fire burns anything. ANYTHING.

Mr T is now 60. Let me repeat that for you, fellow children of the 1970s and 1980s: Mr T is 60 years old.

He could have left all that “I pity the fool” and “I ain’t getting on no plane” stuff behind him many, many years ago. But why let a good catchphrase go to waste? Especially when there’s a whole App Store’s worth of money to made from it.

Another week, another todo list. Given the fundamental simplicity of todo lists as we used to know them (scraps of paper with stuff scribbled on), it’s amazing that there’s so much endless innovation in the field of virtual ones. But so it goes, and Finish is one of the latest apps to try and add a new twist. And mostly, it succeeds.

Hands up if you remember Dial-a-song. You don’t? Man, those were the good days. Even if you don’t remember them, now’s the time to re-live them on your iPhone. Like it’s an old phone. A dial-a-song phone.

Vine is a new, free toy from Twitter. It replaces text with video, but only six seconds of it at a time, shot instant-by-instant. And it’s much cooler than I expected it to be.

The Bookcase is a three-dollar pocket database for your book collection, one that takes its role very seriously and might be best suited to people with a professional requirement to manage a large library.

Meet Carrot, the getting things done app with an attitude. If you’re good and you actually do the things you add to its list, you’ll be rewarded. But if you don’t … actually, things get much more fun if you don’t.
