Watch app on iPhone won’t open??

can somebody help me with this? I recently acquired myself a series 5 Apple Watch from my cousin, it’s all good and nice for a day until all of sudden I can’t open my Watch app in my iPhone.

The watch itself is fine. I thought the problem lies with the watch so I unpaired the device with my phone. However when I wanna re-pair the devices, my Watch app keeps stubbornly crashing so I can’t use my watch for now. (As I need to pair it with my phone.. but the Watch app won’t open.) is there any solutions for this problem? I hope someone have an answer for this soon enough.

Apple Watch Series 5, watchOS 7

Hi Niko, 


I was having the same issue and didn't want to factory reset my phone either. So, I kept trying out different things and actually managed to get the app completely erased and then redownloaded successfully, without doing a complete erase and reset of my phone!! I'll share with you the steps that I took and hopefully this works for you too! I'm thinking the issue might be what lam_serge said below.. not having my phone updated to the latest IOS software 14.3 when I paired my watch. If that is the cause, then hopefully Apple fixes the issue because that is ridiculous! Hope they fix it permanently either way. Anyway, see what I did below.


  1. On the watch go to settings > general > reset > Erase All Content and Settings
  2. Go to your Bluetooth settings on your phone and if you see your Apple Watch, click on the 'i' and click "Forget this device"
  3. Go to "appleid.apple.com", scroll down to devices and you should see your apple watch. Click your apple watch and select "Remove from account".
  4. Next you will need to turn off "Find my iPhone", which should turn off activation lock on the watch. On your phone go to settings > click your name > Find My > Find My iPhone > toggle this off
  5. Next step (not sure if necessary) is to go go settings > general > iPhone storage > scroll to the Watch app and "Remove all backups". I saw someone do this somewhere else, saying that there might be corrupt files in the backups, so removing them might be a good idea. If you do have a backup and want to try without this step, it might still work, just wanted to mention this.
  6. These next steps have to be done kind of quickly. What I did next was do a Hard reset of my phone (quickly press volume up > quickly press volume down > press and hold side button until Apple logo appears and then release side button). Once the phone turns back on, you should have enough time to be able to get into the app and then unpair the watch, but you have to do this super quickly before the app kicks you out. Make sure your app is on the first screen once you unlock your phone, because you don't have much time from when the phone turns on from the hard reset to when the app will fail.
  7. Next, go into the app, and once loaded, quickly press "All Watches" in top left screen > Click the 'i' next to your watch > then click "Unpair Apple Watch". Because you turned off Find my iPhone in the previous step, this should have turned off the activation lock, so you shouldn't have to type in your Apple ID password.
  8. After you click "Unpair Apple Watch", you should see a screen where it shows it is unpairing your watch. Once I got to this point, the app didn't kick me out and I was successfully able to unpair my watch.
  9. After the unpair is completed, go back to your apps and you should have the ability to completely delete the Watch app. First remove the app from your home screen and then completely delete the app from the app library.
  10. After you have deleted the app, you can go back to the app store and download it again and you will be able to get into the app and start over with your watch.


So far my watch and the app seem to be working fine. It's only been about an hour, but so far so good. I really hope this works for you and others! I'd be curious to know if this works for you, or if I can explain anything better. I feel bad for all these people who are having this frustrating issue!

Chances are that you have two iPhones working at the same time. Simply try and pair your apple watch with the iPhone that hasn't been used for the apple watch. When you begin to pair your device on another iPhone, you will immediately be able to delete the apple watch app on the other iPhone. Once you delete it, you can stop pairing on the other device and redownload the apple watch app on the device you wanted it on.


Really irritating but worked for me.

Sad to find out a backup and restore was the only way, hopefully Apple is more than aware and comes out with a fix soon, especially with the holidays near. First real major disappointment with Apple I am sorry to say.


I consider myself tech savvy and would not expect my Mom to be able to backup and restore, a very lengthy process and very possible to lose all your data if not very careful and methodical.

Hello guys I have an iPhone X and a few days back I bought the Apple Watch SE. 6 days until today everything was fine. Suddenly the watch app on IPhone didn’t work. I tried everything but the only thing that worked was to reset to factory settings the iPhone and then the Apple Watch. IMPORTANT DELETE THE APP AFTER THE RESET TO IPHONE. If you try anything else is just a waste of time.

Please note that the iOS 14.3 didn’t fix the problem.

Thank you Rach_01.....this worked for me!! I was not willing to do a factory reset, but I was trying everything else that was suggested! Fortunately, I went through all the comments and found this last post! I followed the exact steps as they were written and it fixed the issue!!! A couple comments about specific steps.....


Step 5 - I went ahead and removed the watch backup. To be honest, I am not even sure it had been backed up, but only having the watch for a couple days, there wasn’t much info to lose.


Step 6....”These next steps have to be done kind of quickly.”....For me, it had to be done very quickly!! It took me 5+ times to get into the app fast enough, but once I did, everything went exactly as listed in the steps above!


Again, thank you Rach_01 for taking the time to write all the steps. Hope it works for others also!

Hi Rach,

It worked for me! Thank you very much!

Just additional inputs on:

6. My phone asked for a passcode at startup. It probably burned some extra time (I tried to disable the passcode in the phone settings, but wasn't able due to device management of my phone).

7. The Watch app additionally asked for confirmation after I clicked "Unpair Apple Watch". I actually had no time to read a message, was able to only see Cancel and another option. It was really challenging to do all these steps on time. I put my phone on a table and used several fingers. It took me about an hour of trying to unpair my phone.

iPhone 11, Software Version 14.3.

Thanks for all these suggestions but I was too slow for this to work for me. I have a new SE watch and a recent iphone SE 2020. They worked fine together for 2 days then this problem arose. Eventually I think I've solved it by resetting the watch back to factory settings, resetting the iphone and erasing all data, recovering the data from icloud to a date a week ago (before I had the watch), updating to IOS 14.3, then pairing and setting up the watch afresh. I lost a weeks worth of data on the iphone (not photos or emails though, they all survived), and everything I had on the watch. I think the critical thing was making sure 14.3 was installed before pairing.

Ridiculous problem. I hope you all find a way through

I had this same issue and could not find an appropriate solution until today. Unfortunately, it was quite time-consuming and not a simplistic process.


Background: I had just gotten my Apple Watch a few days prior to the Watch app crashing, so I was not worried about losing the data currently on it. That being said, I erased all of the content from the watch in the hopes that I would finally be able to delete the Watch app from my iPhone and start over with the process. When this did not work and I was left with a Watch app that wouldn't open and a watch that could no longer be paired, I contacted Apple Support.


Solution: After trying a number of small fixes (ex. resetting the devices, updating my iPhone), I ended up having to back up my iPhone to iCloud, erase all content and settings, and then restore my iPhone using that latest iCloud backup. Once the phone was restored, I was able to delete the Watch app, restore the Watch app, pair my watch with my phone, and update the watch to the latest version of iOS. This resolved all of my issues, including with the Activity app.


Hope this helps!
