Scalado's latest 99 cent app for iOS only does one little thing, but it does it well. Its singular mission is to let you share an image from your Camera Roll to any web-connected display in front of you, without having to navigate through a more sophisticated file-sharing platform or use extra hardware on the receiving device. That recipient can be anything -- a smart TV, tablet, PC, Mac, games console, whatever -- so long as it has a browser pointed at the Photobeamer homepage. That page displays a QR code, which provides all the clever linkage you need: you simply load up the app on your mobile, pick the image you want to share, and then point the rear camera at the QR code to beam the image across via the web.
Having given it a quick test, we'd say it's definitely up to regular domestic challenges where you just want to display a few photos rather than perhaps videos or presentation slides, and where there's no need to print or store shared images. You can swipe left and right between different pictures in your gallery, and also choose whether you want those images to be fitted to the recipient display or resized to fill it. There's a video after the break to help you decide if that's worth a dollar, while the Photobeamer app itself waits patiently at the iTunes link below.
