Simplebooklet is extremely easy to use, with bright colorful icons, drag and drop, and not a hint of technical language anywhere. Like any presentations tool it's based around individual pages/slides, to which you can add images, text, files, video, music, webpages (as screenshots), and even your own HTML code. Once the presentation is finished, it can be published via the major social networking tools (Twitter, Facebook etc.) and you can even embed it within your own website via an iFrame, for which the code is automatically generated.

Simplebooklet is free for up to 20MB of content, and allowing the creation of unlimited booklets, with various yearly plans starting at $10 for more storage space.

Working across different timezones can be a pain, and if you frequently travel to other countries scheduling meetings can become a mind-melting exercise. World Time Planner is a simple app that lets you click and drag a slider to see what the time will be in various cities over the next 24 hours. Daytime and nighttime symbols appear alongside each city to indicate at a glance when the working day starts and finishes. Never before has it been so easy to schedule a breakfast meeting in Singapore while you're sitting in your Boston office.

World Time Planner is entirely free of charge and, unlike some of the apps listed here, works if the computer is offline too.
