Elements - Dropbox Powered Text Editor lets you share and edit text (TXT) files on your iOS device via Dropbox. Dropbox is a free program (Windows, Mac, iPhone) that lets you quickly transfer files between platforms with a folder that automatically syncs up between the devices to make moving files a breeze. You'll also need to register with Dropbox in order to use Elements. But with Elements, you'll now have a separate folder in Dropbox where you can place text files and edit them on your iPhone or iPad. Any changes you make will be automatically synced to your desktop computer's Dropbox, making it easy to work on the go.
Elements is an excellent--if a bit expensive, in iPhone app terms--app with several features that will be useful to those who use text editors for writing, coding, or taking notes. The advantage of text editors over standard word processors is that they are flexible, fast, and totally cross-platform. Added features in Elements include full text search of all your files; a handy info pane that tells you word counts, line counts, and character counts; a separate Scratchpad where you can take quick notes; and TextExpander support so you can bring in your commonly used text snippets to save time. Overall, if you use text editors in your work, or just want a way to sync up text files across your iPhone, iPad, iPod Touch, and desktop computers, Elements is a great choice.
