Watch not syncing with iPhone activity app

I had the same problem, and contacted Apple Support as well. Did unpairing and pairing again as they suggested, but it didn't work.

Then I noticed that in the Health app, the Activity section didn't work at all, there is a "reset data" button, but it does nothing. So I chose to erase and restore my iPhone, then reset and paired the Watch as a new device. Everything finally starts work, but I've also lost all my data.

I also have this problem. I have tried all the suggested solution, but non of them worked. It doesn't take a while to sync, sync AT ALL!

I have restarted my iphone and apple watch, set the progress update to none and deleted all other activity apps on my iphone but the problem still remains! Any new solution?

Even though the original question's been long answered, I'll add my bit in case others find this discussion in the future. My solution was discovering I had BlueTooth turned off on my phone. Once I turned that back on, all good again.

So, I just got the Apple Watch 2 and it does the same thing, will not sync for days. I rebooted the phone and that seemed to work. However, I got a warning on my watch that it was in Airplane mode, which was weird because I checked the phone and it was not.

This has happened to me also in the last few days. I know that my data is still saved somewhere on my watch (and potentially phone) as I am getting achievements for hitting goals, however nothing bar these achievements and saves workouts (previous to Jan 5 2017) are syncing. It is very frustration and disappointing!

Same problem. Many of the solutions previously proposed have been working, but this seems to be one-shot. I read somewhere that the iPhone and the Watch need to be left charging next to one another for 8 hours a day - a target difficult for me to achieve because I only sleep 5 to 6 hours a day.

Eventually the data on the Apple Watch are not lost, as they end up charging on the iPhone, but that is VERY slow.

I wish Apple coulkd come up with a solution to fix this.

I think this might be a good answer. I use "Human" app to sync as mentioned earlier and even so all day Sunday I couldn't get a sync. Finally I noticed my phone had Airplane mode on for some unknown reason. When I turned it off, everything synced.

I seemed to have solved the problem by removing the battery save mode. Once I did everything synced. I noticed that the app refresh wasn't on because on battery save mode it won't do the push sync. Hope this actually solved my problem and it's not a temporary fix

I got a week ago my Apple Watch 3 and I am so frustrated the activity app is not sinking plus it only lasting 1 day and I need to charge my Apple Watch again. How can fox this?

I am super close to return this Apple Watch!! Help!

I have an iPhone 8 and watch 3 and they stop syncing on a daily basis and I don’t get an accurate record of my activity. Very frustrating. Come on Apple, way too much money spent for this level of reliability!

Mine syncs, but it takes a WHILE. I haven't figure out what triggers the dump, but I have noticed it definitely takes some time after I finish a workout before the activity app on my phone updates.

YYep mine synced the first three days then nothing since despite restarting. Unbelievable Apple missed this.

TThere is a setting on the iPhone watch app. Scroll down to activity / progress update. I switched mine to none and it synced straight away.

Same here. I used to reboot the phone and it would sync but not anymore.
