One of the most fantastic advantages of Apple products is their continuity — a seamlessly integrated environment between all your devices (iPhone, Apple Watch, AirPods, Mac) using Apple-only features like iCloud, Apple Pay, AirDrop, or Handoff.

Using iOS integration technology, users can:

• Wirelessly send photos, files, websites, and videos to a nearby Apple device
• Start working on one device and then resume their work on a nearby device without any delays
• Copy content on one Apple device and paste it on another Apple device^[[1]]
• Pay with their iPhone or Apple Watch when shopping online on Mac
• Receive phone calls and SMS on their Mac, share an Internet connection between devices, and do many other activities seamlessly^[[2]]

Due to this well-developed integration within the iOS environment, mobile designers and developers have more flexibility with the app's functionality. For example, a mobile fitness app that tracks running, cycling, and walking is most beneficial when downloaded on a user's Apple Watch. Integrated with the iPhone's Health app, it can share users' progress, distance, steps, or duration and receive optimized activity analysis and health recommendations.
