Peptide Tracker & Calculator

About Peptide Tracker & Calculator

Peptide Tracker is an iOS app for tracking GLP-1 and peptide treatments with a focus on private, local-first data storage. It helps people log doses, manage schedules, and keep treatment details organized without requiring an account. The app is built for tracking Semaglutide, Tirzepatide, and other peptide routines, and it supports both simple logging and more detailed treatment records.

The app is designed for people who want a structured way to follow dosing plans and review their treatment history. Users can record each dose with amount, unit, time, injection site, and notes, then edit entries later if needed. It also supports reminders and schedule management for daily, weekly, or interval-based dosing, including start and end dates, pause states, and reusable templates.

Peptide Tracker also includes tools for more advanced treatment planning. It can model multi-phase dose titration, automate on/off week cycling, and show phase status and timing on a visual timeline. For tracking treatment context, it includes peptide inventory, injection site rotation tracking, side effect logging, missed dose detection, and health marker reporting. The app also offers a peptide dose calculator and a half-life visualizer to help users understand dose timing and treatment patterns.

Privacy is a central part of the product. The site says data stays on the device by default, with no sign-ups and no servers, and sync only when the user chooses. It also supports iOS screen widgets so users can view their next dose and log from the widget without opening the app.
