Can you connect the Galaxy Watch4 to iPad Air 2 or iPadOS 15 or above

Short answer: no.

Longer answer: Unfortunately, the Samsung Galaxy Watch4 is not officially compatible with iPads, including with either iPadOS 15+ or the iPad Air 2. Samsung's Galaxy Wearable app, which is required to set up and manage the watch, is only available on Android devices and not on the App Store for iPads or iPhones.

Why It Won't Work:

• No iOS/iPadOS Support – Samsung's Wearable app is required to set up and sync the watch, and it is not available for iPad or iPhone.
• Bluetooth Pairing is Limited – Even if you manually try to pair via Bluetooth, you won't be able to sync notifications, install apps, or use Samsung Health.
• Android-Only Setup – The Watch4 requires a Google account for setup, which is only possible through an Android device.
