We're having such fun with the Harrods Magazine app! Yes, there's lots about gorgeous clothes and accessories and lust-object homewares, but we're all about beauty - and what they offer on that front is just genius.

Each edition, Harrods takes several brands, showcasing them in a 'virtual makeover' tool.  First, choose your colouring. (There are five models to decide between.) Next, choose your brand: right now, it's Shu Uemura, Dolce & Gabbana, Laura Mercier.

Then select colours from the swatches in eyes, lips and cheeks, swipe your fingers over the face and hey, presto! Make-up appears. (It won't let you add eyeshadow to lips, or vice versa - but you get a fantastic idea of how make-up changes a look, so fast- and whether a colour might suit you).

The magazine also offers fantastic writing:  it was shortlisted for no less than three Jasmine Awards in the latest line-up from The Fragrance Foundation, in their customer magazine category.

Hours of entertainment, honestly.

Best of all?  It's free, to iPad-owners - just click here to find it at the iTunes store.
