Watch not syncing with iPhone activity app

Yeah having the exact same problem, its seems to take hours at times even when connected to WIFI. Restarting the app doesn't work but restarting the phone seems to do the trick. Would be nice if it would sync more often or there was at least an option on the phone app to force a sync.

Apple Watch, IOS 8.3

Since I got my new phone, my activity tracker will not synchronize with my iWatch. I've tried all the tricks - rebooting, turning off/on airplane mode, changing progress updates to none, and unpairing. Nothing! Any other ideas. It hasn't worked in a month.

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.

Update to my last message.

Yesterday it came to the point that my Watch (Apple Watch 2) and my iPhone (IPhone 6) did not synchronise at all during the whole day. With much reluctance, I decided to un-pair the Watch and re-pair ir with the iPhone.

In order not to lose any data, I decided to let them a chance to synchronise during the night and do it when I'd wake up. Luckily, they synchronised during the night so I didn't lose any health data. I re-paired the Watch chosing the "safeguard of a former watch" option (as opposed to "pair as a new watch"). The operation enabled to solve the issue - most likely until it reappears. 😕

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.

IM having the same issue. Rebooting phone worked once, but just noticed that all of yesterday's updates didn't get to activity app on iPhone, although the badges I earned for the activity dId! So I know the watch synced since I now have badges that reflect correctly, but don't match the activity level stored on phone. Weird.

My activity app isn't syncing either. It's strange how things USED to work, but no longer do. I've had the watch for 12 days, and apparently have only stood during the first 3 days. Walks outside used to register as workouts, and now I get 0 minutes on the exercise wheel (even when starting the activity using the workout app). It's pretty frustrating since I only got the watch for the fitness aspect. Fitbit is looking pretty good right about now.

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