Hello, iOS and the Mac app always offer quite different workouts on the trainnow feature to each other. Are they using different algorithms. Which app would be the most accurate? Has anyone else noticed this?

TrainNow suggests optimal workouts for your current abilities, based on your Progression Levels in each power zone and your desired workout duration. Because our workout library is so extensive, there are usually multiple workouts available that fit the bill. Pressing shuffle or looking on another platform prompts TrainNow to suggest different options from within this list of suitable workouts. ✌
