Individual metabolism does not differ by huge amounts. It's essentially height x pulse x temperature and if any of those three change you'll be the first to know.
All of those formulas are extremely rough, as is our ability to measure what we're eating. I'd stay out of the calorie hedge maze for a while and focus on making every food have a purpose. Decide your protein and micronutrient-rich foods first then add in clean fats and/or carbs to achieve energy balance. Grok didn't have apps.
