Frequently Asked Questions
What is StackCheck and how does it work?
StackCheck is an AI nutrient tracker that analyzes what you eat and provides personalized supplement recommendations. Log meals by photo or text, track 30+ nutrients against your health goals (energy, hormones, longevity), and discover which supplements you actually need based on your diet — not generic advice.
How is this different from MyFitnessPal or Cronometer?
MyFitnessPal tracks calories and macros. Cronometer tracks micronutrients but stops there. StackCheck goes further: we track 30+ nutrients against your specific health goals AND give you personalized supplement recommendations based on what's missing from your diet — all backed by 580+ peer-reviewed citations.
How do I know what supplements I actually need?
Most people guess — or follow generic advice. StackCheck analyzes your actual diet to find nutrient gaps, then recommends only the supplements you're missing. If you're already getting enough Vitamin D from food, we won't tell you to take it. Your recommendations are personalized to YOUR intake, not population averages.
How accurate is AI food logging?
Our AI identifies dishes and ingredients from photos, then pulls micronutrient data from USDA and verified nutrition databases. You can adjust portions and ingredients before confirming. It's faster than manual entry and accurate enough for tracking trends — which is what matters for supplement recommendations.
What nutrients does StackCheck track?
We track 30+ nutrients including Vitamins A, B6, B12, C, D, E, K, Folate, Thiamine, Riboflavin, Niacin — plus minerals like Iron, Zinc, Magnesium, Calcium, Potassium, Selenium, Iodine, Copper, and Omega-3 fatty acids. Each nutrient is mapped to specific health goals like energy, sleep, hormones, and longevity.
Is StackCheck free?
Yes — StackCheck offers a free trial with full access to AI food logging, micronutrient tracking, and personalized supplement recommendations. After the trial, basic tracking remains free. Pro unlocks unlimited AI analysis and detailed reports.
