The Apple Watch Series 9 is the best choice for iPhone users. It runs on WatchOS and has many apps to keep you from having to pull out your phone. The Series 9 is almost the same as the Series 8 but can process Siri requests on the watch, making it faster and more private (unless Siri needs to search the web).
With the new S9 chip, it’s more efficient and has slightly better battery life, though you still need to recharge it regularly. The coolest new feature is Double Tap, which lets you tap two fingers together to accept or reject calls, reply to messages, start or end timers, and more.
