If you want to present an idea or just create a cool word cloud, Wordsalad for iPhone and iPad takes a bunch of words and generates a beautiful image that you can export in full HD in PNG or PDF formats. The app is able to pick out the most important words and bring those forward, filtering out unimportant words like articles, prepositions, and pronouns. You can customize the result by changing fonts, colors, and word layouts. Great for posters, presentations, and brainstorming, Wordsalad is $2.99 in the App Store.
