Biostacks vs Rekko

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.

Rekko is the macro tracker built for people who are serious about their nutrition - not another generic calorie counter. Adaptive macro targets that actually adjust as your body changes, an AI coach that knows your real data, and logging fast enough that you'll actually keep doing it. WHY REKKO IS DIFFERENT Adaptive Macros, Not Guesswork Most apps set your targets once and never touch them again. Rekko's adaptive algorithm tracks your real weight trend against your goal and adjusts your calorie and macro targets automatically - so your plan keeps working even as your body changes. An AI Coach That Actually Knows Your Data Ask Rekko Coach anything - "how's my weight trending," "am I hitting my protein," "why did my calories go up this week" - and get answers built from your real logged history, not generic advice. Ask for a trend and Coach can generate a real chart on the spot. Log Food However's Fastest for You Search a real food database, scan a barcode, or just describe your meal in your own words and let AI estimate it - with a confidence level and source shown for every AI-estimated item, so you always know how reliable a number is. See Your Real Trends, Not Noisy Data Weight naturally bounces day to day from water retention and normal fluctuation. Rekko smooths your weight trend so you can see what's actually happening - plus a real TDEE (calorie burn) estimate that updates and charts over time, not just a one-time number. Wearable-Informed, Never Wearable-Controlled Connect your Apple Watch, WHOOP, Oura, or other wearable for recovery, sleep, and HRV insights with a real personal baseline - context for your coaching, never something that silently changes your targets behind your back. BUILT FOR YOUR GOALS Whether you're losing fat, building muscle, improving performance, or maintaining - Rekko calculates your targets using established nutrition science (Mifflin-St Jeor BMR, activity-adjusted TDEE, goal-specific protein/fat ranges) and explains exactly how, if you ever want to know.
