Or even while cycling if your phone shows well enough in the bright sun and you don't mind the extra battery drain.
The Ant+ or Bluetooth will allow you to use that sensor with most any of the common GPS/Cyclometer makers should you later decide to pony up the money for a decent head unit. IE. Garmin or Wahoo.
This. I use a set of Wahoo speed and cadence sensors with the Wahoo smartphone app via Bluetooth. Both work well indepedent of the weather (at least where I ride). The cadence sensor comes with a rubber case that covers the sensor and attaches to the crank arm. Very easy to install.
