FillGap

Snap your meals. Snap every supplement you take. FillGap combines them across 40+ nutrients and shows what's still missing, where your supplements overlap, and what's over your limit β then what would close each gap. Built for people eating less on GLP-1, women in perimenopause, plant-based eaters, and anyone already taking supplements. WHO FILLGAP IS FOR - On GLP-1 medications: smaller appetites make protein, fiber and key vitamins and minerals harder to reach. FillGap tracks nutrition only; it does not track doses or injections. - In perimenopause: keep an eye on nutrients like calcium, vitamin D, iron and protein as your needs change. - Plant-based: check protein, B12, iron, zinc and omega-3 from food and supplements together. WHY FILLGAP IS DIFFERENT Your meals and supplements should work together, not sit in separate logs. FillGap combines both in one nutrient calculation, so the supplements you take count toward the gaps your food needs to cover. One portfolio. Both inputs. All 40+ nutrients. Supplement overlap: see when more than one supplement gives you the same nutrient β and whether the combined total is more than you need. HOW IT WORKS 1. Snap a meal photo or scan a packaged food's barcode. Snap your supplement labels β FillGap reads the Supplement Facts and dosages β and save them to your collection. 2. FillGap uses AI to identify foods and estimate portions, with nutrient information from USDA and other food databases. Review and edit before confirming. 3. Log the supplement doses you actually take from your saved collection, with unit and dosage selection. Log several at once; repeat doses stack into one row. Confirmed meals and logged doses contribute to your nutrient totals. 4. Review today's intake and your 7-day nutrient portfolio. See what's below target, within range, or above a recommended limit. 5. Get practical food and supplement suggestions based on your remaining nutrient gaps. YOUR NUTRIENTS, AT A GLANCE Buy, Hold, Sell, and Profit turn nutrient tracking into a portfolio you can understand and act on. Open any logged day in your history, or compare each nutrient's average intake with its target by month or custom range.
