iOS/Web: Most apps that automatically generate things like images or web pages end up looking like crap. Adobe's new free app Spark can do a bit better job than most. The app lets you quickly design nice-looking images for Facebook, Twitter, Instagram or your own blog with a handy selection of presets. Pick a size, colour palette and title themes. You can also choose from ready-made templates to design videos and web pages. Spark will guide you through each step, doing all the heavy lifting behind the scenes. Most of the themes are stylish and modern, which gives it a leg up over most of the competition. It also allows a lot of flexibility, if you want to avoid making a cookie-cutter image just like everyone else using the same app. On iOS the app is split into three parts for posts, videos and web pages, which you can find here.
