Running and cycling are very different than weight lifting. Easy to calculate automatically with an app.
That said, I think the market of weight lifters with good technique who use barbells is much smaller than the market of casual weight lifters/gym goers.

I use Garmin to track strength training too. I find that peak heart rate during heavy lifts is a good indicator of cumulative central nervous system stress from running.
What do you make of Strava? Tons of elite runners and cyclists use it. I use it, Garmin Connect, Elevate, and various others to track my fitness. I would say that the vast majority of people who are "into fitness" use apps to track their fitness.
