A: Apologies for the delay in response.
Couple of primary differences between Friday and Rork. Friday is a general purpose coding agent, which means you can build mobile apps, web apps, wp sites, desktop apps, along with automating your marketing, asset generation etc. Rork is specialized specifically in mobile apps, and its a web based platform (vs Friday is desktop based).
Friday builds React Native apps, so you can easily publish IOS and Android apps from the same codebase. Rork uses Swift UI which is not reusable. Overall, you can accomplish building mobile apps with Friday and much more.
