Apple Watch - workout app freezes

I just started having this problem a little while after installing 4.3.1 on S3 (no LTE).

Workout app would freeze upon opening and then be responsive 10-20 seconds later, another symptom was my battery life had decreased. I wear the watch overnight (sleep tracking) and it has a 100% charge before bed. In the morning it would be sitting at 94-96% consistently then this problem arises and it started sitting at 80-84%.

I also noticed that when I checked the Usage section in General settings (first thing in morning) of the Watch app on the phone it was saying that watch was active for ~5 hr and standby of ~9 hr. This has been going on for at least a week now.

So today woke up and watch is at 95% charge, usage is 25m, 9 hr standby and Workout app is completely responsive no lag?

The only thing that I can recall doing differently yesterday was installing 3 apps to the watch ( and checking that they worked after install). So I'm wondering if somehow some previous app install was stuck in limbo i.e. trying to install but not quite getting there and thus constantly putting a drain on the CPU and battery and interfering with Workout app being able to start up quickly. Just a theory but perhaps my installing the other apps kickstarted it?

I also have this issue. It seems to be getting worse and it's super frustrating when trying to start a workout. It also does it consistently every time I use the workout app. Might try taking it in to the Apple Store

I have the same freezing on a brand new iphone x (setup as new) and my first apple watch s3. I suspect it's trying to get a GPS lock. I need test if it's better in an open space or not.

Same here. After one of the updates the workout app gets stuck as soon as I open it. I need to wait a minute before it works again.

That's because you're reset the watch. I got a new series 3, reinstalled from backup. Worked great for a week. After a week it started to lag again.

I'm having this exact issue with my Apple Watch Series2... Whenever I'm launching the workout app - Doesn't matter if I do it from the "widget" or from the app menu. I get the Workout main screen but the screen is unresponsive for ~30secs. After that time it works just fine... Until when I'm finishing my workout. Again when I swipe right to get to press the finish workout I get another period of unresponsivenes...

I've tried to factory reset both - My iPhone 7 and my Apple Watch but nether did anything to the issue... What ***** that this is pretty new issue - can't remember that this was an issue ~month ago...

Hi

Whilst I can't say why that is happening, the following steps may help:

Close certain apps and restart both your iPhone and your Apple Watch:

• Close the Watch app, Activity app and Health app (if open) on your iPhone:
  • Double-click the Home button, then swipe up on each app preview to close the apps.
• Turn both devices off together, then restart your iPhone first:
  • Restart your iPhone, iPad, or iPod touch - Apple Support
  • How to restart your Apple Watch - Apple Support

If the issue persists, next unpair and re-pair your Apple Watch:

• The Watch app on your iPhone takes a backup of your watch automatically when unpairing via the app.
• Initially choose to Restore from Backup during set up (most data and settings will be restored, with some exceptions, such as Apple Pay cards, passcode).
• If the issue persists, consider instead unpairing and setting it up as a new watch.
• Unpair your Apple Watch and iPhone - Apple Support
• Set up your Apple Watch - Apple Support

If the issue still persists, then I suggest that you contact Apple Support (remote diagnostics and/or mail-in service may be available, if required), make a Genius Bar reservation or visit an Apple Authorised Service Provider for assistance:

• US: Apple Watch Service Answer Center - Apple Support
• Elsewhere: Apple - Support

Still struggling with the issue... Don't know if it sheds any light, but I noticed that it's the first start of the Workout app thats sluggish... And in the matter of fact it seems that nearly every app that I launch for the first time In the watch behaves nearly the same: Apple Music, Shazam, Reminders, Mail - Get the pattern? Every app takes a ton of time to load... Feels more like watchOS1 then watchOS4 that supposed to improve the launch times of watch apps.

i have the exact same issue. whenever i open the workout app, it freezes for ~30 sec or so and then finally start to work.

all the rest of the app are a bit slower after the 4.2 update but still acceptable.
while the workout has become almost impossible to use.

i know have to anticipate and open it a couple of minutes before my workout which is ridiculous.
i hope there will be a fix for this as it's very annoying

I have the same issues as others in this thread, and none of the suggested fixes have worked for me. Thanks for bumping it up for support. I suspect it is a software issue, no problem for me at initial 4.0 launch.

Add me to the list of people with this same problem. Mine locks up for 10-15 seconds on the first launch in a day... then will run fine through my workout. But when trying to relaunch the app the next day - I get the freeze. It's almost like it's trying to load itself back into ram. Very frustrating when trying to sync to start running with the treadmill starting.

I also have this problem! I have tried all the things suggested in this thread. Nothing works 😟

It has started happening since watchOS 4.0 on my Watch Series 2.

I loved my watch now it is really annoying to use as I mainly need the workout app and it almost always is frozen for a long time at first.
