Re: I'll...
I'll be able to tell if my heart rate is within the necessary range to improve my cardiovascular health when I'm walking and it'll record improvements over time without any hassle unlike some of my previous heart rate monitors.
I don't tend to find silent mode much use when I'm out and about walking in the streets. I usually miss calls because I can't feel the vibrations as I'm not a hipster wearing skinny jeans. YMMV.
