StackCheck is a nutrition tracker that shows what your food is actually giving you, and where it falls short. Snap a photo, scan a barcode or nutrition label, or just say what you ate. StackCheck breaks each meal into 30+ nutrients, not just calories, and measures your intake against recommended daily amounts. YOUR GAPS, UP FRONT Dashboard, Reports and History open with the nutrients your meals are short on. Tap any meal to see exactly what it contributed. FOOD FIRST Most gaps can be closed with food. StackCheck shows the foods that cover a gap, and tells you when a supplement you take is already covered by what you eat. HONEST NUMBERS A meal's total is always the sum of the items you confirmed, and the app flags when its estimates of a portion disagree. Recommendations cite peer-reviewed studies you can open and read. LOGGING THAT FITS REAL LIFE • Log to any day, and fix a meal's serving or date later • Meal Prep: plan your week and log straight from the plan • One evening reminder that skips days you've already logged BUILT FOR YOUR GOALS Energy · Sleep · Immunity · Focus · Longevity. Tell StackCheck what you're working towards and the analysis follows it. SUBSCRIPTION StackCheck Pro is an auto-renewable subscription, available monthly or annually.

  • This app hasn’t received enough ratings or reviews to display an overview.

Your nutrient gaps now lead the Nutrients tab, each with foods that close it — matched to your diet. Reports keep going when you leave the screen. Start one, carry on using the app, and the Reports card tells you when it's ready. Photo scanning survives switching apps mid-scan instead of giving up. Food suggestions now respect vegan, vegetarian and other dietary restrictions. Plus accuracy improvements to your reports.
