There are several apps that I can use–but I most often it’s the “Walk” app on a Garmin Vivoactive 4 smartwatch – which then syncs with the CityStrides website.
And I totally get street photography–which is really rewarding too. I call it being in “Photographer Mind”–where I literally interact with the world differently: a much more visual orientation–which can be very meditative and relaxing. I love it!
