I do not have workout app on my apple watch se? I cannot find it in App Store, help

It should be there, unless you accidentally deleted it. I suggest the following route to troubleshooting.

• Restart your Apple Watch, just in case it's a simple display glitch. The quick and dirty fix is the force-reset method, Restart your Apple Watch - Apple Support
• Try commanding Siri to start a workout, "Hey Siri, start a workout" to see if the app is still present but you don't see it.
• Download again from the App Store It must be there somewhere, but it seems to be well hidden amongst the third party apps and like you I couldn't find it. In the worst case it might be easier to erase your watch and re-pair to download and setup all the software again. The unpairing should create a backup to your iPhone, so just make sure you did a backup of the iPhone to iCloud. Be aware that health and probably also workout data WILL need an encrypted backup (default for iCloud but not if you backup to a local computer).

After trying all the fixes I found here and elsewhere, but still unable to restore workout app and unable to find in AppStore with keys “workout” or “Apple workout” which shows a million 3rd party apps but not apple workout, this is how I restored my workout app:

Went to safari in iPhone and Google searched apple workout. Then texted the link to the workout app related to apple AppStore from search to myself. Then opened the message app in my Apple Watch and clicked the link to App Store link to workout app from the message to myself and finally found the app to download directly to my watch. The workout app cannot be downloaded to iPhone. It can be downloaded only to Apple Watch.

Thankyou so much this worked. After trying for a while. Many Many thanks.

My “workout” app also disappeared. But as you said i searched from the Google and send it to myself via message. Opened message with my watch and download the app. Thank you very much!

Thank you, Thank you, Thank you!! This worked for me.
