Answers about Peptide Tracker app and GLP-1 app features for GLP-1 dose logs, reminders, Apple Health sync, injection sites, exports, and half-life tracking.
Peptide Tracker includes a large compound library covering a wide range of peptides. This includes FDA-approved GLP-1 receptor agonists like Semaglutide and Tirzepatide, research peptides, and compounds in various stages of approval, clinical trials, or international use. The app is a tracking tool - it does not make claims about the legal or regulatory status of any compound. You can also create custom compounds and blends if yours is not in the built-in library.
All data is stored locally on your device by default. The Peptide Tracker iOS app collects zero treatment telemetry, uses no in-app analytics or in-app third-party tracking, and does not operate any servers that receive your health data. If you enable iCloud sync or Apple Health, those services are handled by Apple under Apple's own terms. The app has no access to that data. See the full Privacy Policy for details.
The half-life visualizer models how compound concentration changes over time based on pharmacokinetic decay. It shows decay curves between doses and estimates steady-state levels based on your schedule and the compound's half-life. You can visualize multiple compounds at once to see how overlapping protocols interact.
Yes. Peptide Tracker reads nine health metrics from Apple Health: weight, resting heart rate, heart rate variability (HRV), body fat percentage, lean body mass, waist circumference, blood glucose, and blood pressure (systolic and diastolic). Data syncs automatically each time you open the app, with daily averages calculated for each metric. You can toggle individual metrics on or off in settings. The app also includes correlation analysis that charts your health trends against your dosing timeline, so you can see how metrics like weight or blood glucose change relative to your protocol.
Schedules support three frequency types: daily, weekly (choose specific days of the week), or interval-based (every N days). Each schedule has optional start and end dates with pause and resume support - pauses can be indefinite or date-bounded. Dose titration lets you define multi-phase ramp sequences with configurable dose amounts and durations per phase, including a final maintenance phase. Therapeutic cycling supports on/off week patterns for compounds that require breaks. You can save reusable schedule templates and titration templates for quick setup. Notifications support customizable title and body text.
The calculator includes six modes: Dosage (dose-to-volume conversion), Reconstitution (bacteriostatic water ratios), Steady-State (time to reach stable blood levels), Blend (component breakdown for multi-peptide mixes), Cycle (on/off protocol planning), and Half-Life (decay timing between doses). You can also try the web dose calculator and reconstitution calculator. Each mode shows a real-time syringe visualization with insulin unit markings so you can see exactly where to draw. It handles the full reconstitution workflow: enter vial size in milligrams, water volume in milliliters, and target dose - it outputs the volume to draw and equivalent syringe units. For blends, the calculator breaks down each component's individual contribution per injection.
The app maps 11 body areas with up to 15 positions in the abdomen alone, covering all standard subcutaneous injection zones. Four preset packages (Quick Start, Abdomen Full, Upper Body, Lower Body) let you set up rotation quickly, or you can define custom sites. Each injection is logged with date, compound, and optional reaction tracking across six reaction types with severity rated 1 to 5. The rotation algorithm suggests the least-recently-used site and enforces configurable rest days between uses. Sites are color-coded by status - ready, resting, or recently used - so you can see your rotation at a glance. Learn more in the Injection Site Rotation Tracker guide.
Yes. Peptide Tracker supports 34 biomarkers across nine categories: Hormones (testosterone, estradiol, IGF-1, growth hormone, cortisol), Liver (ALT, AST, GGT, bilirubin, albumin), Lipids (total cholesterol, LDL, HDL, triglycerides), Blood (hemoglobin, hematocrit, RBC, WBC, platelets), Kidney (creatinine, BUN, eGFR), Thyroid (TSH, free T3, free T4), Prostate (PSA), Metabolic (fasting glucose, HbA1c, fasting insulin), and Inflammation (CRP, ESR, ferritin). You can set custom reference ranges with unit conversion for each marker. All bloodwork data is stored locally on your device.
Enable opt-in iCloud sync in settings to back up automatically across all your Apple devices. Sync triggers when you open the app, after any data change, and via background polling every 15 seconds while active. Your data is stored as a single backup_data.json file in your private iCloud container - covering all 17 data collections including peptides, doses, schedules, inventory, bloodwork, injection history, and preferences. Conflict resolution uses last-write-wins merging. You can also export your data manually in CSV, plain text, or PDF formats, including a medical-format report suitable for sharing with your healthcare provider. iCloud-stored data remains in your Apple account.

Yes. Peptide Tracker can log Semaglutide injections with dose amount, unit, date, time, injection site, notes, reminders, and schedule history. You can use it to track medically prescribed Semaglutide treatment patterns, monitor consistency, rotate injection sites, and compare your dosing timeline with health metrics such as weight, glucose, heart rate, or blood pressure when Apple Health is connected. Peptide Tracker is a tracking and education tool, not a source of medical advice. See the Semaglutide Tracker App guide.
Yes. Peptide Tracker supports Tirzepatide dose logging, weekly or interval-based reminders, titration phases, inventory tracking, injection site rotation, side effect notes, and provider-ready exports. You can track your treatment history over time and review how schedule changes line up with health metrics. Always follow your prescribed treatment plan and consult a qualified healthcare professional before changing dose timing or amount. See the Tirzepatide Tracker App guide.
Peptide Tracker can track custom compounds and blends, including pharmacy-compounded or user-defined entries, when you need to record inventory, concentration, dosing schedules, and notes. The app does not verify the legality, quality, safety, or regulatory status of any compounded medication. Confirm all medication details with your prescriber and pharmacy before entering or following a protocol. See the Peptide Inventory Tracker guide.
Yes. Peptide Tracker can export filtered reports in PDF, CSV, or TXT formats so you can share dose history, schedules, inventory notes, side effects, injection site history, bloodwork, and health metric trends with a healthcare provider. Reports are generated from data stored on your device and can be used to support a medical conversation, but they do not replace professional diagnosis or treatment guidance. Side-effect recordkeeping is covered in the Peptide Side Effect Tracker guide.
No. Peptide Tracker is for informational, educational, and tracking purposes only. It helps you record treatment details, visualize schedules, model half-life curves, and organize health data, but it does not diagnose conditions, recommend medications, prescribe doses, or replace a licensed healthcare professional. Always consult your physician or another qualified provider before making treatment decisions.
Yes. Peptide Tracker stores your GLP-1 and peptide tracking data locally on your device by default. Dose logs, schedules, inventory, notes, bloodwork, side effects, and health metric records remain under your control unless you choose optional integrations such as iCloud sync or Apple Health. Peptide Tracker does not operate servers that receive or store your treatment logs.
