Press and slide on the Size button to adjust brush size and make a simple selection of the skin you want to smooth. With the overlay button selected you can easily trace the selection if any parts have been missed (Image credit: Jason Parnell-Brookes) To demonstrate, we'll make some adjustments to the image above. And then there are overlays (two circles), crop options, selection tools, healing, red eye, text options, stickers and borders. The first tab on the bottom gives you preset themes, then you have 'looks' (the icon shows three interlinked circles these are basically filters, from white balance filters to black and white and duo tone). Some of the effects are free, while others are marked with a star to show that they're only available with a premium subscription. Large thumbnails show how each one will affect the image.

You might recognise some of the tools from Photoshop, but the layout looks much like other mobile editing apps, or even a platform like Instagram, offering a range of filters and quick use tools. Photoshop Express sits somewhere between Photoshop and many of the image editing apps available for iPhone. We'll edit this image to show how to Photoshop on iPhone (Image credit: Jason Parnell-Brookes)
