It's the very same application in terms of features and functionality. Here are the differences between buying Fade In Professional Screenwriting Software for Mac OS X directly from http://www.fadeinpro.com and buying it from the App Store:
- If you buy it from the App Store, you receive the benefit of easy, integrated updating. Updating with the non-App-Store version is still pretty easy, but you'll have to install any update yourself.
- However, the App Store version will very likely be updated less often. This is because, during times of heavy development, new builds of Fade In have often been released two or three times a week. Since Apple's application approval process can take up to several weeks, the latest will be submitted to the App Store once it has been out long enough.
- If you purchase from the App Store, you will get the full version of Fade In Professional Screenwriting Software for Mac OS X only, linked to your Apple ID. If you purchase directly from the website, you will receive a registration key for the full version enabling you to use it on OS X, Windows, and Linux. Apple does not currently provide a way to transfer App Store purchases to non-App-Store purchases and vice-versa.
