Cocoa Touch (iOS) vs Bubbles: What are the differences?

Developers describe Cocoa Touch (iOS) as "The Cocoa Touch collection of frameworks includes everything needed to create iOS apps". The Cocoa Touch layer contains key frameworks for building iOS apps. These frameworks define the appearance of your app. They also provide the basic app infrastructure and support for key technologies such as multitasking, touch-based input, push notifications, and many high-level system services. On the other hand, Bubbles is detailed as "Drop comment bubbles anywhere on the screen, on any website". It is a Chrome extension for UX and web designers. It allows you to drop comments anywhere you click on a webpage. You also get a unique link to share those comments with your teammates. Your teammates can reply and resolve those comments in real-time.

Cocoa Touch (iOS) and Bubbles can be categorized as "Frameworks (Full Stack)" tools.
