A quick roundup of iOS text editors with Dropbox support
First, let's take a look at PlainText (see screenshot above). Hog Bay Software is the same company that publishes the wonderful WriteRoom application for Mac and iPhone, which we've covered many times here on TUAW.
Once PlainText is installed on your iPad (it also works on iPhone and iPod touch), you can tap the settings button to change Dropbox settings, turn on TextExpander support, or lock the screen orientation. Since I wanted to test several of these text editors with Dropbox but did not want to have a ton of new folders created in my Dropbox, I loved the fact that I could link to an existing folder. As soon as your Dropbox credentials have been verified, more settings become available. Most of those are related to when synchronization takes place.
According to a note from Grosjean, there can be an issue when files are not saved on a computer using UTF-8 encoding. If a file is opened with PlainText and appears blank, the computer didn't save the file with the proper encoding. What's interesting is that I had this issue with another text editor app, and the developer of that app didn't seem to know what the problem was.
I personally like PlainText more than any of the other text editors I've used. It's clean, easy to use, allows you to delete files and folders with a swipe, and Grosjean has obviously put a lot of thought into the design of the UI. The app icon is a large, black editor's paragraph symbol on a white background, which is extremely easy to find. The app is free, using iAds to defray the cost. Grosjean wants you to be able to remove the ads by doing an in-app purchase for $4.99, but the in-app purchase option is still in review by Apple.
Next, there's Elements (US$4.99) from Second Gear. This is the app I've used for quite a while, until one of the other bloggers here at TUAW pointed out PlainText this morning. As with PlainText, Elements is a plain text editor. In the file list mode, the newly-updated Elements lets you sort documents by name or modification date. It does not, however, let you create folders in Dropbox, which I find to be a real negative.
Elements has support for spell check and TextExpander, and it's possible to change the font, text size, text color, and background color easily in order to make it easy to read the document. Do you want green text on a black background? You've got it.
I know this is a nit-picking comment, but I don't like the icon for Elements. It's supposed to be a composition notebook with a black-and-white speckled cover, but to me, it looks like static on an old TV instead. Elements is a universal app, running on any iOS device.
Droptext ($0.99) from Invisions Technical Arts is another universal app that works well with Dropbox. It's the least expensive of the apps (if you don't count the ad-supported free version of PlainText), but it has many of the features that the other apps enjoy -- it has TextExpander support, it can create files and folders from within the app, and it allows customization of the writing environment (font, size, text and background color).
iA Writer ($4.99) is an iPad-only app, which makes it slightly less useful than the other three apps we've discussed here. From Information Architects, Writer is probably the most focused on just ... writing. It has a Focus Mode that takes all distractions off of the screen. There's no auto-correction, no spell check, no toolbars, nothing. You can clearly see the last three lines of text that you were working on; everything else is grayed out.
The app has a beautiful monospaced font that it uses to make your text more legible as you're reading over it. There's a tool that calculates how long it will take to read your text; that's great if you're writing a script or speech. Information Architects is planning on adding auto-syncing, subfolders, word count, and other sync services in the near future.
