4 cups popped (~40 g) has about 200 calories.
Why estimates miss: Buttered Popcorn is a multi-ingredient dish. Air-popped is under 120 kcal, but added butter or movie-theater oil nearly doubles it. Generic calorie apps undercount the hidden oil, sauce and portion — CalDesk AI's photo estimate is tuned to catch exactly this.
