Unpopular opinion: my fancy smartwatch is a total waste now
I was at the gym in Tempe last week and my $400 watch died right in the middle of tracking my run. I had to finish the last two miles with no data, and it made me realize I don't need half the junk it tracks. What's a good, simple fitness tracker that just does the basics without all the apps?
You're throwing the baby out with the bathwater because of one dead battery. That data is the whole point, it shows your progress over time. A basic tracker won't give you the same insights on heart rate zones or recovery. Maybe just charge your watch before the gym next time.
