I strongly disagree. I feel like involving my smartphone into any activity that existed in 1990 (like jogging, or riding a bike) tends to make things more complicated, not less. When I go for a jog wanting to listen to podcasts, battery status, headphones, Bluetooth and playlist ordering are additional complexities that, at the very minimum, add additional steps to the process and, at worst, require several minutes of problem-solving before I can get started.
In my experience, involving a smartphone can, but rarely does, make things simpler.
