It multiplies the calories burned by your characters total level divided by 10. This means as you gain levels in OSRS, you get more experience per calorie. We recommend setting up the app with a partner who can password protect the bonus task feature as well as keep you accountable to staying within your xp limits. You will need a fitness device that logs active calories burned to Apple Health. Apple watch is what this app was tested with.
