Biostacks vs VitalFill

Biostacks is a supplement tracker. It does not tell you what to take. It shows the research behind supplements, additives, and interactions, with sources, and lets you run your own experiments on your own numbers. We make no health claims. Sources are research papers and meta-analyses on PubMed, NIH fact sheets, FDA and EU regulators, and the bodies that certify and license brands. Stack Analysis and research: • Supplement and medication interactions, from NIH Office of Dietary Supplements fact sheets and PubMed studies, each with a link • Synergies between supplements, from PubMed meta-analyses • Research coverage for 18 health goals, from sleep to longevity: what the meta-analyses found and the doses they studied • Upper limit warnings and RDA coverage for vitamins and minerals, from NIH and USDA reference values, with the harm NIH lists for going over • Additives checked against FDA GRAS rules and the EU food additive regulation • Brand records: NSF, USP, Informed Sport, Kölner Liste, NZVT, and Eurofins certifications, Health Canada licences, FDA warning letters, and FDA, UK, and French recall notices • Nutrient overlaps between products Experiments: • Daily check-ins on mood, energy, sleep, and focus • Metrics: weight, sleep, resting heart rate, HRV, steps, or any custom number, with Apple Health sync • Scan a lab report, blood test, body composition, or aging report from a photo or PDF, read on your phone, never uploaded • Run an N-of-1 trial: three weeks off and three weeks on, alternating weekly. The result says whether a metric moved, or "no effect" when it did not • Experiment results appear only after enough logged days Supplement scanner and vitamin tracker: • Barcode scanner with your camera, for supplements, vitamins, pills, and medicine • Search NIH DSLD and Open Food Facts, with popular brands available offline • Enter supplements, medications, doses, and nutrients manually • Ask Apple Intelligence (iPhone 15 Pro and newer) • Use your own assistant like Claude, ChatGPT, Grok, or Gemini to manage your stack with a copy-and-paste prompt Supplement schedule, pill and medication reminders: • Daily, specific weekdays, or on/off cycles like 5 days on, 2 off • Multiple times of day, from multivitamin to magnesium • Peptide tracker and peptide calculator: vial size, reconstitution, and draw volume • Dose reminders, with smart tuning when you keep logging late Dose log: • One tap per dose, mark a whole stack at once, long-press to skip and keep your streak • Progress rings, streaks, and dose logging by asking Siri • Taken, due, and upcoming groups, and a calendar with mood dots • Search, filter, notes, reorder, and dark mode • Adherence and Stack Analysis trends over 30, 90, or 365 days, with CSV export • Monthly cost per supplement and per stack, and running-low refill alerts On-device AI chat: • Review your routine, explain an ingredient, or change your stack by describing what you want • Every suggested change appears as a review you accept or reject, with undo Privacy first: • Works offline with no account • Your health data stays private, on your device • Optional backup and sync to your own iCloud • Snapshots and version history to roll back any change • Export everything as JSON or PDF, or share a stack as plain text Everyday intake tracking is free: dose logging, streaks, reminders, check-ins with trends, the library and barcode scanner, export, import, and backups. Biostacks Pro, an annual subscription with a 7-day free trial, adds Stack Analysis insights, check-in correlations, experiment results, report scanning, Apple Health metrics, historical trends, cost tracking, smart reminder tuning, cloud sync, and the on-device AI assistant. Whether you take vitamin D, omega-3, zinc, magnesium, creatine, collagen, or protein, or run a supplement stack with nootropics and peptides, Biostacks keeps the log, the research, and the experiments in one private place.

VitalFill turns nutrition into something you can see. Log what you ate. Pick any nutrient — vitamin D, iron, magnesium, leucine. A human figure fills up to show exactly how much of YOUR daily need you've covered. Not a generic label percentage. Yours. WHY IT'S DIFFERENT Most trackers count calories and stop there. VitalFill asks what actually matters: are you getting enough of what your body needs? Free, your targets are the standard FDA reference — the same numbers on a Nutrition Facts label. Upgrade and they switch to your own numbers, calculated from NIH Dietary Reference Intakes using your age, sex, height, weight and activity level, and adjusted for pregnancy or breastfeeding. Two people logging the same meal can then see different results, because their needs differ. FOUR WAYS TO LOG • Search — over two million foods from the USDA FoodData Central database • Barcode — scan any packaged product, unlimited and free • Photo — snap your plate and let AI identify it (1 free scan/day) • Voice — just say "two eggs and a slice of toast" (3 free logs/day) WHAT YOU CAN TRACK Calories, protein, carbohydrates and fats — including saturated, monounsaturated, polyunsaturated and cholesterol. Every vitamin from A to K. Every essential mineral. All nine essential amino acids. Fiber and sugars. Every one of these is free — see below. BUILT FOR PRIVACY No account. No sign-up. No email address. We never ask who you are. Your profile and food log stay on your device — we hold no copy. Voice logging transcribes speech on your phone; no audio ever leaves it, only the resulting text is sent for parsing. Photo and recipe scanning send the photo to Anthropic's Claude API for recognition only; it's never stored. There are no ads, no analytics, and no tracking of any kind. SEE THE WHOLE PICTURE • Daily status for any nutrient, as a filling figure • Coverage view showing every nutrient at once • Biggest gap — what you're most short of today • Which foods contributed what • Look back at any previous day DATA SOURCES Nutrient values come from USDA FoodData Central. Daily targets come from NIH Dietary Reference Intakes. Every nutrient links to its source. VITALFILL FREE Every nutrient, every score, unlimited barcode scanning, one AI photo scan a day, and 3 voice logs a day — all measured against the standard %DV reference. No nutrient or score is hidden behind a paywall; only personalization is. VITALFILL PRO Pro switches your score and every target from the standard reference to numbers calculated from your own age, sex, weight and activity level. It also adds: • Scan any recipe or ingredient list and get a nutrient density score for the whole dish • Save a favorite meal once, log it again in one tap • Full history and 30-day trend charts, by day or by individual meal • 14 photo scans a day and 60 voice logs a day (vs. 1 and 3 free) SUBSCRIPTION DETAILS • VitalFill Pro Annual — 1 year, with a 3-day free trial • VitalFill Pro Lifetime — one-time purchase, no subscription, ever Annual: payment is charged to your Apple ID account at confirmation of purchase.
