Those who know me know that Byword has become my favorite writing tool. I've been keeping my mouth shut about this release during the beta testing period, but I'm really excited to announce it's arrival: Byword for iOS. The iOS version includes the Markdown-editing features that I love on the Mac, and has full iCloud and Dropbox sync between devices.
There's an update to the Desktop version as well, enabling iCloud support for the multi-device sync. You can start typing on your Mac, pick up your iPhone and walk away, then continue typing wherever you end up. Your text is ready and waiting for you.
Byword for iOS is a universal app, and one price gets you editing bliss on your iPhone, iPad and iPod touch (or whatever combination you happen to have). The price is starting at US $2.99, and will start going up by $1 every three days until it reaches its standard price of US $4.99.
Byword for Mac is available on the Mac App Store for $9.99. Even without the new iOS companion app, it's an excellent writing tool. Portability just makes it that much more useful to me.
If you write on a Mac, and especially if you write in Markdown (see the TUAW Markdown Primer) Byword is a gorgeous and elegant environment to do it in. The feature set looks sparse; everything just works. You don't need to see a bunch of buttons, you can just type. Features such as automatic list continuation, selection wrapping, and unobtrusive word count just happen, and additional requirements are filled by keyboard shortcuts. It's worth every penny to me.
