I do not see a forum listed for the Vivo line, so I apologize for posting here.
I'm a longtime user of the vivoactive HR watch and I love it. It does exactly what I need with a long-lasting battery, even still, years later. The app is great and other than the occasional bluetooth hiccup where I have to delete the watch from my phone and re-sync, it generally works fine.
That said, I am considering a newer option, or at a minimum want to have something ready to order without having to do a lot of research in the event this one fails. I see there is still a vivoactive 4 on the website, but is it discontinued? What are other watches that have a touchscreen which are similar but perhaps more updated (multi color display, maybe some app integration such that I don't always have to take my phone with me on shorter runs, etc.)?
