If you're a writer, journalist, editor, or student, you've probably heard of AP Style. Well, now you can download the entire style manual as an app right on to your iPhone or iPod touch!
The app is searchable, offers suggestions for writing styles, and allows you to make notes.
The only drawback is that the app costs $28.99, whereas the printed edition costs $18.95.
If you are using the AP Stylebook a lot, and don't want to carry the spiral bound booklet around with you, the app may be worth the price.
