I dunno. This just doesn't quite compute to me as some universal principle.
I paid $30 for a year of Strong (an iOS fitness app), for example. What do you see as the "allotment of resources" there? They're delivering maintenance upgrades and feature releases periodically that I'll use any time I log a workout; the app runs on a phone that I own; the data is presumably sitting on a server of theirs, so it needs to be ready for whenever I want to use it.
I've logged ~40 workouts so far, so let's hope I stay consistent and end up with 80 for the year. That's ~38 cents per workout.
I just don't feel ripped off here, especially since I moved off of a fitness app that I liked less and cost $50/year, the price has stayed the same over four years while improving steadily, and I'm not aware of anything that does what I want for a better price. I'm not sure I'd even want some kind of metering system; psychologically I don't like the idea that I'd have to spend a second thinking about if I want to pay more to log more workouts.
