PeptidePal is a peptide and GLP-1 protocol tracker used by over 150,000 people — dose logging, vial inventory, injection site rotation, reconstitution math, scheduling, and a 110+ compound library in one app. Whether you're on a prescribed GLP-1, running your first protocol, or managing several compounds on different schedules, PeptidePal keeps it all in one place. WHY PEPTIDEPAL? ◉ BUILT FOR PROTOCOLS, NOT PILLS: Generic medication apps track one pill, once a day. PeptidePal handles mcg, mg, IU and mL, cycles, on/off weeks, site rotation, and vial lifecycle. ◉ NO DRIFT: Three weeks in, it's easy to lose track of whether you're on day 9 or day 12. PeptidePal keeps the protocol you designed and the protocol you're running the same thing. MAIN FEATURES: ▶ PROTOCOL BUILDER Build from the library or from scratch. Set dose (mcg, mg, IU, mL), frequency (daily, every other day, twice weekly, 5-on/2-off, custom), days, start date, notes, and reminders. Run multiple protocols side by side. ▶ DOSE LOGGING & CALENDAR One tap to log. A week strip and monthly calendar show completed and planned doses, injection site, and time. Streaks keep you consistent. ▶ VIAL INVENTORY & SUPPLY ALERTS Log fill size, concentration, and expiry. PeptidePal projects each vial's run-out date from your live schedule and warns you about a week ahead. ▶ RECONSTITUTION MATH Enter vial size, diluent volume, desired amount, and syringe size. PeptidePal does the mg/mL arithmetic and shows it on a syringe diagram, with an over-capacity warning. Unit conversion only — PeptidePal does not recommend a dose. ▶ INJECTION SITE ROTATION Tap-to-select on an interactive body map, with recently used sites heat-mapped so your rotation is visible at a glance. ▶ COMPOUND LIBRARY 50+ profiles in plain English: mechanism, half-life, research status, reported side effects, and considerations. Every entry states its regulatory status. ▶ PROGRESS & LEVELS Weight and body-composition charts, progress photos with compare and time-lapse, and an estimated on-board level curve from your logged doses. Educational estimate, not a measurement. ▶ AI ADVISOR & COMMUNITY Q&A Short, plain-English answers to educational questions, plus a moderated peer forum. The AI will not recommend a dose, titration, or protocol, and routes medical questions to a provider. You're talking to an AI, not a clinician. Does PeptidePal work with prescribed GLP-1s? Yes — track Ozempic®, Wegovy®, Mounjaro® or Zepbound® with the same scheduling, rotation, and supply tools. Dosing decisions belong with your prescriber. Is my data safe with PeptidePal?

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.

Verdict
The clearest difference is ads: Biostacks at none against PeptidePal's shown. Biostacks also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 18.0). PeptidePal's advantage is ratings volume (4.8K vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. PeptidePal sells 19 in-app purchases, starting at $3.99 per 7 days and Biostacks sells 2 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.
Biostacks holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: PeptidePal has 4.8K ratings behind it against 1, so its average is the more settled of the two.
PeptidePal ships an update every 5 days, Biostacks every 10 days. The most recent releases landed on October 20, 2026 and October 6, 2026 respectively.
