Key Points

  • The author is nearing completion of an AI-powered calorie tracker that analyzes photos into individual ingredients and is focused on Apple Health integration before a beta launch in two weeks.
  • They want the app to update dynamically—using activity such as a 500kcal run to adjust future meal macro targets rather than showing only static nutrition totals.
  • The core question for the fitness-tech community is how “active calories” should be handled: strictly based on base metabolic rate (BMR) versus automatically adding earned calories from an Apple Watch to the user’s daily budget.
  • The author is also refining “macro overflow” logic, such as carrying surplus calories into the weekend, and is seeking real-world tracking feedback.
  • Overall, the post is soliciting opinions and design guidance for nutrition-tracking logic and Apple Watch/Apple Health data integration.

Hey everyone,

I'm currently in the final stretch of developing my Al calorie tracker (the one that breaks down photos into individual ingredients). One thing I'm obsessed with getting right before the beta launch in 2 weeks is the Apple Health integration.

Most apps just show you a static number. I want mine to be dynamic. If you go for a 500kcal run, the app should know and adjust your macro targets for the next meal.

My question to the fitness-tech crowd: Do you prefer apps that strictly stick to your base metabolic rate (BMR), or do you want the 'earned' calories from your Apple Watch to be automatically added to your budget? I've seen strong opinions on both sides.

I'm also fine-tuning the macro-overflow logic (e.g., saving surplus calories for the weekend). Would love to hear some thoughts from people who actually track daily.
