Layout is a great iPhone photography app from the same developers as the very popular Halftone app. Usually Layout retails for $1.99/£1.49 but this weekend you can pick it up for only $0.99/£0.69. Click here to download.
Swipe your finger to quickly split a frame into sections, and use the radial menu to add photos directly from Facebook, Instagram, or Flickr. Enhance images with built-in filters and effects, adjust saturation and contrast, add some stickers, and a whole lot more. Then, add a caption to each photo, apply a background color or pattern, and share your layout with friends and family via e-mail, Facebook, Twitter, and Flickr. If you want to go back, Layout includes undo and redo, and best of all, you can store your projects in iCloud to share them with other devices.
