Biostacks vs VitalFill

Biostacks helps you track, understand, and improve your supplement routine while keeping your data private. Build your supplement library by: • Scanning barcodes with your camera • Searching NIH DSLD and Open Food Facts data (well-known brands and popular supplements available offline) • Entering supplements, doses, and nutrients manually • Asking the built-in Apple Intelligence assistant (iPhone 15 Pro and newer) • Asking your own AI assistant with a ready-made copy-and-paste prompt Create routines and schedules that match how you take things: • Daily, specific weekdays, or on/off cycles (like 5 days on, 2 off) • Multiple times of day, from a morning multivitamin to an evening magnesium • Peptide support: vial size, reconstitution volume, and a draw-volume calculator Then get insights into your stack: • StackScore, a 0 to 100 quality score for your whole routine • Potential interactions based on public research, each with a source link • Warnings when a nutrient total goes over its safe upper limit • RDA coverage across your vitamins and minerals • Nutrient overlaps between products • Brand quality and trust signals • Adherence history and score trends over 30, 90, or 365 days, with CSV export • Monthly cost per supplement and per stack • Running-low refill alerts Log doses with one tap, mark a whole stack taken at once, and long-press to skip a dose without breaking your streak. Reminders keep you on schedule, and smart tuning suggests a better reminder time when you consistently log late. Progress rings and streaks show your consistency day by day. You can also log a dose by asking Siri. Your day, organized: • Doses grouped into taken, due, and upcoming • A calendar of every past day, with mood dots from your check-ins • Search and filter once your stack grows • Notes on stacks and on individual supplements • Reorder stacks and items to match how you take them • Dark, light, and system themes Check in daily on your mood, energy, sleep, and focus. View your trends, run on/off experiments, and see whether a supplement moves the numbers. Correlations only appear once there is enough data behind them; Biostacks will not show you a pattern it cannot stand behind. Ask questions in the 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. Prefer your personal assistant? Copy the prompt, paste the answer back, and review the changes the same way. Privacy first: • Works fully offline • No account and no sign-up • Your health data stays on your device • Optional backup and sync to your own iCloud • Snapshots and version history, so you can roll back any change • Export everything anytime as JSON or PDF, or share a stack as plain text Everyday tracking covers dose logging, streaks, reminders, check-ins with rating trends, the library and barcode scanner, export, import, and backups. Biostacks Pro, an annual subscription with a 7-day free trial, adds StackScore insights, check-in correlations, historical trends, cost tracking, smart reminder tuning, and cloud sync. Whether you take a daily vitamin D and omega-3 or manage a full stack of supplements, nootropics, and peptides, Biostacks gives you one private place to log your intake, stay consistent, and understand how your routine fits together.

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.
