Peptide Tracker & Calculator is a private iOS app for managing peptide and GLP-1 treatments, combining dose logging, scheduling, inventory tracking, half-life visualization, and health metric imports into a single local-first tool.
What is Peptide Tracker & Calculator?
Peptide Tracker & Calculator is an iOS app that lets individuals privately log peptide and GLP-1 doses (including Semaglutide and Tirzepatide), schedule daily/weekly/interval reminders, and model plasma concentration curves. It accepts manual dose entries, Apple Health data (weight, heart rate, HRV, body fat, glucose, blood pressure), and CSV bloodwork files, then produces adherence heatmaps, half-life decay charts, and exportable PDF/CSV/TXT reports. The app is developed independently by one person, stores all data locally on-device, and requires no sign-up or server connection.
Key Features
- Dose Logging — One-tap quick log with optional details (amount, unit, time, injection site, notes); edits and deletions auto-adjust inventory.
- Half-Life Visualizer — Plots decay curves and steady-state levels for one or more compounds based on dose history and built-in half-life data.
- Reconstitution & Dose Calculator — Converts peptide powder to liquid volume and syringe units; includes dedicated reconstitution calculator and dose-to-volume converter.
- Inventory & Stock Alerts — Tracks vials, pens, sprays, topicals, and orals with expiry, batch, price, and storage; auto-deducts stock on log and warns on low/expired items.
- Apple Health Sync — Imports weight, heart rate, HRV, body fat, glucose, and blood pressure; correlates treatments with health metrics over time.
- Therapeutic Cycling — Automated on/off week treatment cycles with current phase status and next phase timing.
- Bloodwork Management — Log lab results against custom or standard ranges; scan lab reports to extract values; bulk import from CSV with column mapping.
- Smart Notifications — Custom reminder templates with variables (e.g., compound name, dose amount) and auto-cancel after logging.
Who is it for?
- Individuals on GLP-1 therapies (Semaglutide, Tirzepatide) — Logs doses, schedules weekly injections, and models half-life to track steady-state and missed doses.
- Peptide protocol researchers or self-experimenters — Manages custom compound blends, titration ramps, and cycling phases, with inventory tracking for vials and bacteriostatic water.
- Healthcare providers or coaches — Reviews patient adherence via consistency heatmaps and exports filtered PDF reports with graphs for clinical collaboration.
What can you do with it?
- Schedule a multi-phase Tirzepatide titration — Build a dose ramp with custom durations and maintenance phases, then view the phase timeline with active/upcoming status.
- Visualize Semaglutide decay — Enter dosing history and see real-time plasma level modeling alongside the built-in compound half-life library (100+ compounds).
- Log and analyze injection site reactions — Select from 13+ injection zones, track rest days, and attach photos to side effect entries with severity and intervention notes.
FAQ
Is Peptide Tracker & Calculator free?
The app is free to download and start using. There is no subscription or paid tier mentioned on the product page.
Does the app require an internet connection or account?
No. All data stays on-device. There are no sign-ups, no servers, and no third-party analytics. iCloud backup is opt-in and uses your Apple account.
Can I export my data?
Yes. Reports can be exported in PDF, CSV, or TXT formats with optional graphs and summary statistics, suitable for sharing with a healthcare provider.
Does it support brand-name GLP-1 drugs?
Yes. Presets are available for Wegovy, Ozempic, Mounjaro, and more, with auto-filled concentration, vial size, and titration schedules.
