Biostacks: Supplement Tracker

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.
