I find it useful if it's mostly automated. I use a basis band for sleep & activity, and a fitbit aria scale for weight. It being automated doesn't stress me out and it's useful to have a history to see trends. I also find it fun to start some runkeeper app when I go on bike rides, and that only takes about a minute or two before I start it. I never actually look at the history of my cardio workouts, but it's fun to have the stats while I'm biking, and to see a map of where I went after I'm done.
