I’m a fan of screenwriter John August. Not just his writing (Big Fish, Go) but of his blog as well. Now John has written an app for screenwriters (and readers).
If you read screenplays on your iPad, FDX Reader is must. It works in conjunction with Dropbox (another must have app). It converts final Draft 8 files (.fdx) in your Dropbox to PDFs — automatically. Now you can review works in progress on your iPad without having to remember to save it as PDF and email it to yourself.
But why listen to me? Get more information from the horse’s mouth here: FDX Reader for iPad | johnaugust.com.
And then subscribe to John’s blog. Whether you’re screenwriter or just play one on TV, it’s a great read.
