My Writing Spot
My favorite writing app so far, this lets you write, edit and backup your document on the web. It has a powerful dictionary and thesaurus tool, lets you specify your own font and best of all, gives you the option to password-protect.
Evernote – capture notes and sync across all devices. Stay organized.
This uber versatile app lets me write from whichever gadget – iPhone, iPad, MacBook Pro and syncs every change I make.
