The update of the sneaker brand's customizing app features Photo iD, a tool that lets you match your shoes' colors to any photo taken with your iPhone, meaning perfect matching to your outfit, your room or whatever you fancy.

The Shoe Salon

New York department store Bergdorf Goodman's application has launched a full frontal attack on your wallet, giving you one shoe per day that can be shopped directly from your phone. Available to US customers only.

OPI

Nails are the ultimate fashion accessory this spring, so it's no wonder that specialist OPI has released its iPhone app. Working closely together with fans of the brand using social networking media, OPI lets you 'try out' all nail polish colors on the phone with this first version. Updates are already in the making.

Chanel

The luxe label has launched a new application that can also be accessed online: the re-interpretation of a slot machine gives you three new gift ideas, sorted by accessory category, each time you spin the wheel.

Highlights of the app include a tool that lets you place the issue's star, Abbey Lee Kershaw, into any picture taken with your phone, which you can then share on POP's website.

Covering the shows in all major fashion capitals, FNO has lots of interesting info but - contrary to what its name suggests - doesn't add anything new to the pool of fashion week apps, pioneered by the likes of style.com.

Shop View - London

Oxford Street in the heart of London is Europe's busiest shopping mile, and finding your way around all the stores and special offers might seem daunting to many. Enter Shop View: the $1.99 app gives you a 3D tour of the local shops plus links to their websites and Twitter feeds of special sales.

The serious approach, however, has a serious price too, compared to other apps: the guide sells for $9.99.

Inditex - Zara

Before the Spanish chain's online store goes live, Zara has released an iPhone app that is designed to facilitate your shopping through collection lookbooks, detailed pictures of the clothes and immediate access to its stock. Plus: the app alerts you of new arrivals.

Target

The US retailer's application is even more extensive than Zara's, featuring a store finder telling you exactly what is currently in stock at your nearest store, special offers, and even a gift finder as part of its offering. In addition, the app lets you comment and review items for other shoppers' reference.

myFendi

The ultimate application for the Fendi fan lets you classify your favorite looks by the label and locate the closest store. As a special gimmick, this app also mixes and matches Fendi items with the clothes in your wardrobe.
