GLP-1 Tracker App

GLP-1 Tracker App is a fitness tool. Peptide Tracker is a local-first iOS app for logging GLP-1 and peptide doses, managing inventory, visualizing half-life curves, and syncing health metrics without sending data to a server.

Peptide Tracker is an iOS application built for people managing GLP-1 or peptide treatment protocols who want detailed logging without handing their health data to a server. It covers the full lifecycle of a protocol: dose logging with site and timing detail, multi-phase titration ramps, on/off therapeutic cycling, injection site rotation across 13+ zones, and side effect tracking with photos and severity ratings. A compound library with more than 100 entries and brand presets for products like Wegovy, Ozempic, and Mounjaro speeds up setup by auto-filling concentration and vial size. Beyond logging, the app models what is happening inside the body and in the medicine cabinet. A half-life visualizer plots decay curves and steady-state levels, a dose calculator handles reconstitution and syringe-unit math, and a consistency heatmap shows adherence patterns over time. Inventory tools track vials, pens, sprays, and compounded blends down to bacteriostatic water usage, with auto-deduction on logging and alerts for low stock or approaching expiry. Health context is layered in through Apple Health sync for weight, heart rate, HRV, and other metrics, plus bloodwork tracking with custom ranges, CSV import, and report scanning. Users can export provider-ready PDF, CSV, or TXT reports, set goals against health metrics, and keep dated progress photos with side-by-side comparisons. All of this runs locally with no sign-up requirement and opt-in iCloud backup only, positioning the app as a privacy-first alternative to cloud-based health trackers or generic logging spreadsheets. It suits self-directed peptide and GLP-1 users, biohackers, and patients who want to bring organized data to appointments, rather than casual users looking for a simple weight-loss app. The depth of the calculators and inventory system assumes some familiarity with dosing terminology and reconstitution concepts.
