Why don't I see the Apple Fitness app in the Apple App Store from my iPad Air (updated to latest iOS)?

Your iPad needs more that just the app.

Your iPad needs to be updated to the latest iPadOS 14.3, or later.

You need a compatible Apple Watch ( series 3 or later ) updated to its latest WatchOS version and, also, Bluetooth connected to your iPad before the iOS App Store will let you download/install the Apple Fitness+ app.

You need to have or purchase an Apple Watch series 3, or later.

No options.

Also, make sure all connected Apple devices ard using the same Apple ID/password account information.

Best of Luck to You!

You also need an Apple Watch Series 3 or later running WatchOS 7.2 or later.

If you continue to have issues, contact Apple support via the contact support link located at the upper right hand corner of every Webpage of these Apple support communities OR by installing and using the Apple Support app found in the iOS App Store.

Best of Luck to You!

You just connect your Watch just like any other Bluetooth device.

The Watch should just come up in the Bluetooth settings in the Settings app.

And you need to be using two-factor authentication.
