Peptide Library is the peptide tracker and peptide research library in one app, for research peptides and GLP-1 peptides such as semaglutide, tirzepatide and retatrutide. Plan your peptide schedule, get reminders, log every entry, keep your vial inventory up to date and look up any peptide, all in one place. Whether you research one peptide or a full stack, Peptide Library keeps your schedules, log history and inventory organized, on your device first. WHY PEPTIDE LIBRARY? ◉ TRACKER AND LIBRARY TOGETHER: read about a peptide, then add it to your schedule and inventory in a couple of taps. ◉ INVENTORY THAT KEEPS UP: every entry you log updates what's left in your vials, capsules and sprays. ◉ BUILT FOR STACKS: several peptides, several forms, each on its own schedule. ◉ PRIVATE BY DEFAULT: works offline, with optional account sync and backup. PEPTIDE TRACKER • Schedules: daily, every other day, chosen weekdays, or cycles with on and off weeks. • Reminders for every scheduled entry, with one tap to log or skip. • Log entries with time, amount and notes; log several at once and undo a log. • Calendar: month and week views of what you logged, missed or skipped. • Separate schedules for each form of a peptide: vial, capsules or nasal spray. • Site rotation on a body map, with a suggested next site. • Research Streak: counts the scheduled days you complete and earns XP. PEPTIDE STACKS AND BLENDS • Track a whole stack, each peptide on its own schedule. • Save blends and log them together. PEPTIDE INVENTORY • Track every vial, capsule, nasal spray and ready-to-use container. • See what's left, estimated uses left, run-out and reorder-by dates. • Low-stock, reorder and expiry alerts. • Save the price, purchase and opened dates, vendor and COA for each container. JOURNAL, PROGRESS AND BODY METRICS • Journal: daily check-ins for mood, energy, sleep and symptoms, with trends and PDF or CSV export. • Progress photos with a guided camera, timeline and side-by-side compare. • Weight, body fat, lean mass and body measurements, with goals and trend charts. • Works with Apple Health: bring in your weight and body fat (optional, read only). PEPTIDE RESEARCH LIBRARY • Peptide profiles with mechanisms, research summaries, half-lives and PubMed references. • Compare peptides side by side and share the comparison. • Peptide School: courses, guides and FAQs. PEPTIDE TRENDS AND COMMUNITY • Peptide Trends: see what the community is researching and popular schedules. • Community Q&A with other researchers. • Compare vendor listings and prices per mg, with vendors that ship to you listed first, and read supplier reviews. WIDGETS • Home Screen, Lock Screen and StandBy widgets for today's schedule, your next entry, your streak and inventory. PEPTIDE LIBRARY PRO Pro unlocks unlimited tracking, blends, courses, progress tools, Peptide Trends, Community, supplier reviews and sync.

Know what to take, when to take it, what inventory you have left, and how your body is responding. Every dose, check-in, and trend stays organized in one private place, on iPhone and Apple Watch. FEATURES • Personalized protocols — Add any peptide or supplement, choose a product or formulation, then set dose, route, dates, reminders, multiple daily times, custom weekdays, every-X-days timing, pauses, on/off cycles, or as-needed use. Group and color related compounds. • 250+ compounds — Browse categories, aliases, evidence context, timing, GLP-1 options, and research sources. Bookmark compounds and links. • Apple Watch — Take, skip, or snooze doses with amount and injection site, follow estimated levels, log weight, mood, symptoms, fluids, and protein, and check your weekly streak. Add progress, next-dose, or level complications. • Fast logging and widgets — Complete scheduled doses, add unscheduled doses, edit actual times, skip with a note, or undo. View upcoming doses and adherence on your Home Screen, mark doses taken from widgets, and take, snooze, or skip from reminders. • Injection sites, reminders, and Calendar — Pick sites on a front-and-back anatomical map, review recent sites, control reminders per protocol, schedule bloodwork check-ins, and add dose or side-effect events to Apple Calendar. • Detailed inventory — Track vials, pens, pills, consumables, batch or lot, concentration, supply, thresholds, opened and expiry dates, and transactions. See dose coverage and projected refills; logging can deduct from a linked container. • Daily and body tracking — Log mood, notes, activity context, rest days, workouts, weight, and body fat. Record side effects with severity, protocol, injection site, timing, and notes. • Fluids and protein — Log water, coffee, tea, and protein against daily goals and review dated history, from iPhone or Apple Watch. • Apple Health — Import height, weight, body fat, lean mass, resting heart rate, HRV, sleep, and steps. Set a local step goal, and optionally save weight and body fat to Health. • Outcome plans and active levels — Set target dates, optional weight targets, your own pace, and dated milestones. View simplified dose-equivalent decay estimates for supported compounds or a half-life you provide. Estimates are not blood measurements or dosing guides. • Progress and history — Explore adherence heatmaps, body trends, wellness, steps, activity, symptom patterns, doses, skips, bloodwork, and inventory transactions. Export progress, stack, and body summaries. • Ask about your data — On supported devices, ask Apple Intelligence when you last dosed or what is running low. Answers use only your Milos data and stay on device. • Lab records — Store dated PDF reports locally and enter biomarker values, units, and lab reference ranges. Milos does not automatically interpret results. • Personalized setup — Choose goals, experience, treatment stage, compounds, reminder preferences, side effects to monitor, and optional measurements. Milos adapts setup and explanations to your choices. HOW IT WORKS 1. Build schedules and groups. 2. Add inventory and thresholds. 3. Log doses, wellness, fluids, and symptoms. 4. Review and share trends. Access requires a subscription.

Verdict
The clearest difference is monetization model: Peptide Library and Tracker at free against Peptide Tracker & GLP1's free with in-app purchases. Peptide Library and Tracker also leads on ratings volume (30 vs 4) and iOS requirement (16.4 vs 18.0). Peptide Tracker & GLP1's advantage is rating (5.0 vs 4.8) and review sentiment (100% vs 88%). On price, update cadence, ads and in-app purchases there is nothing between them.
