I wish Apple would allow me to connect an Apple Watch to an iPad. My 9 year old daughter would love an Apple Watch. It would be great for her b3cause of some heath concerns and activity monitoring. Plus all the cool factors. She doesn’t have a phone yet but she does have an iPad with unlimited data. If I could connect a watch to her iPad, well that would be great. I could pass down a watch to her.
Connect for what? The next version of WatchOS has its own apps store. The iPhone is not needed to 'squirt' apps or data to the watch. The older watches may not scale up to being independent devices, but at this point the newer "hand me downs" will be mostly independent devices.
Would need to synch data through iCloud if want to view data on device with bigger screen. The gap that Apple has is that they need an "Health data" viewer perhaps on the iPad ( they should have one for Mac also) . Apple's "non phone, small screen" work around is the iPod Touch at the moment, but somewhat too focused on just being a Health data collector and skipping substantive "viewer" issues.
Cellular option probably still wouldn't work since no principle phone number/service to share, but there is no phone in this context anyway.
It is the same generational growth that the iPod and iPhone went through where initial coupled to iTunes on bigger device and then as their internet capabilities got better over time largely became independent computing devices ( with just option sync to a "bigger" computer. )
I doubt Apple is going to put effort into backfilling where the Watch was as opposed to more work where the Watch is going in the future. If put better ( lower power consuming) Wi-Fi in the watch then won't need to sip data on low power bluetooth mode most of the time.
It is extremely likely that Apple could sell
WAY more Watches if it was
not very tightly coupled to the iPhone. It is the same thing that boat anchored the iPods for a while ( needed Mac and Firewire). When Apple let the iPod off the Mac only chain it took off. Watch is ramping up to the same "take it of the chain" point. Wear OS (Android) and others have stumbled pretty badly. It isn't urgent because vast majority of iPhone owners still don't own an Apple Watch ( so can still grow substantially just monetizing the iPhone subset. ). But jumping into the bigger market of Watch + some other non iPhone apple device ( a Mac , an iPad coupled to an Android phone . ) is a bigger group than just iPhone by itself.
P.S. When the Watch goes "independent device", Apple really should add a "back up wireless" option to iTunes to go along with what is still left for the iPhone/iPad. Doing 100% local encrypted backups still should be doable without the "Cloud" for those who don't want to use it.
