I’ve also used the Nike Running Club one. I liked it, but not as much. It had workouts for you to do, and soundtracks I think, and it LOVED badges and streaks.
I liked the data and knowing my pace, exact distance. Also, when I ski, it keeps my top speed and top maintained speed.
Also, there was King of the Hill awards for fastest people to do a certain run. Leaderboards and such.
When I did the half, it actually finished at 13.2. This was a certified course. But I figured that was within the margin of error depending on curves and water stations.
However, I’ve tried to use it to track on an indoor track at our local rec. It’s a 1/16th mile track and it doesn’t work at all.
When I did a half, I loved that it kept ur pacing with audio notifications, also your mile splits via ear buds. Also if you tend to run the same course, it keeps track of previous efforts. Also elevation changes in relation to pace. Lots of good data.
I’ve used Strava for years for most all my activities - running, hikes, pickleball, bike riding, skiing, etc.
You can definitely get sucked into the data, which is obviously why you use those sorts of apps.
