Amazfit Watch faces

Hello my dear friends, I have purchased a Haylou RT3 LS16 watches. Now it has a suport on Hello haylou app. You can add a wtchface which is created for LS05S. Small problem is that not every watchface can be uploaded to watch. Hello haylou app is using tbwf format, is there some program in which you can edit those kind of watchface?

I've been looking for the same thing for a long time
