Nike Run Club app update motivates you to run more
If keeping streaks helps motivate you, then you'll appreciate the latest update to the Nike Run Club app on the Apple Watch. It has a new interface that shows "streaks" for running for consecutive weeks. You'd only need to run once a week to keep the streak going, but perhaps that'll incentivize you to keep going.
The app also has other new tweaks, including a new user interface that shows up mid-run. It'll now display your average pace and cadence to help improve your technique.
