Is there any function on, or app for, the Galaxy Watch 3 that allows me to set a strong vibrating notification to mark each move or rest interval during HIIT? Something similar to the HIIT function on the Fitbit (but with a vibration notification that a human being can actually feel!).
I'm asking forums for the Galaxy Watch and HIIT. If I get a useful response anywhere I'll happily post the answer in the other forums and credit the responder.
Apparently the WOD Insight app does what I need it to. The app designer sent me a video of a Galaxy watch vibrating during the HIIT setting on the app, and it appears to be stronger than the wimpy effort of my Fitbit.
