I do a lot of kayaking and would love an activity on the Vivoactive 3 to record my trips. I'm using dwMaps to plan trips and record them but the only activities on the watch are rowing and SUP.
Yes it's a pity ! There some 3rd party apps in connect IQ.
I personnaly use a self developped app but it is until now not accurate in measuring Stroke frequency and efficiency... I have to fix it before giving it. The only positive point is that with it my kayak session are immediately appearing as kayaking in my activity report (don't have to rename it).
