Recommendations for Apple Watch face apps available on the App Store

Beware of Facet by Zimbot. Chinese scammers.

1. It appears to be free and doesn't state that there are any in-app purchases.
2. After having the app for a few hours, the app tells you that you need to pay $6.99 to continue to use the watch faces.
3. A day or so later, because you didn't realize the payment was made outside the App Store they will use the bank card that you used for the $6.99 to charge you another $29.99. My bank wouldn't reverse the charge and to stop any further charges I had to blow up my bank account, getting a new account and a card with a different number..

Most of the watch face apps appear to use Apple's own photo watch face and not many of the complications on their high tech faces actually function.

That's my opinion, YMMV.

M1 Mac mini, macOS 15.5;  Watch, series 10 GPS-only, watchOS 11.5; iPhone 16, iOS 18.5; TV 4th Gen, tvOS 18.5 HomePods, audioOS 18.5

I do not use 3rd party watch faces on my Ultra 2, because the default watch faces provided by Apple offer all options I want and need on my watch. Plus, no additional costs involved and they work as expected and advertised.

Apple will only know about which features we users want, if we use the Feedback link.

As with all 3rd party software, Apple does only allow a certain access to the operating system of their devices, to make sure that the system running stable and the data is not altered or compromised.
