About Pepti – Peptide Tracker
Pepti – Peptide Tracker is made by Tessaro Pty Ltd in Melbourne, Australia. It is an iPhone app for keeping a record of an injectable routine: what was logged, when, where on the body, and from which vial. It records what you enter. It never tells you what dose to take.

Who builds it
Pepti is designed and built by Rehan Udugala, an indie developer, and published by Tessaro Pty Ltd. Tessaro is a software company. It is not a clinic, a pharmacy or a supplier, and it sells no compounds. Nobody at Tessaro is offering medical advice, and nothing in the app or on this site replaces the person who directs your care.
That matters for how you read this site. Every page here is written by the maker of the app it describes, so treat the parts about Pepti as a description of our own product. Where we compare Pepti with other apps, the page says so and shows where each fact came from.
Pepti - Peptide Tracker (App Store ID 6762118154) by Tessaro Pty Ltd is not affiliated with other apps that use the name Pepti.
What the app does
- Logs each injection — the figure you already have, the date and time, the site, and the vial it came from.
- Keeps vial records — what each vial holds, its lot, the date you reconstituted it, its expiry and use-by dates, and what it cost.
- Tracks rotation — twelve sites, so the next injection lands away from the last.
- Reads bloodwork — lab results you import, shown against published reference ranges.
- Connects WHOOP and Apple Health — recovery, sleep, steps and activity alongside your log.
The guide to choosing a peptide tracking app explains each of these in plain terms. The app does not calculate doses, draw volumes or syringe units; the free reconstitution calculator on this site does that arithmetic in a browser.
How the app is built
Pepti is a native iPhone app written in Swift and SwiftUI, and it needs iOS 17.2 or later. Your records are stored on the device using Apple’s SwiftData framework. There is no account system and no sign-up.
Your protocol and health data stay on the device. There is no cloud sync. That data leaves your phone only if you turn on the AI coach or lab-report import, both behind one consent switch, and then only your coach messages with the app context they need, or the report you import, are sent to Pepti’s server and processed by Anthropic. The private peptide tracker page goes through this item by item.
Subscriptions are sold through the App Store: $12.99 per month or $49.99 per year in USD, with no free trial; you can cancel anytime. There is one tier, and every feature is included.
What Pepti will not do
Pepti does not suggest, recommend or adjust a dose, and no page on this site contains dosing guidance. You supply a figure you already have; the app records it. The editorial policy sets out the rules every page here is written to, including which sources we accept and how to report an error.
What Pepti is, and what it is not
Pepti is a record-keeping tool for an injectable routine. It has been on the App Store since 27 May 2026 under the name “Pepti - Peptide Tracker”, in the Health & Fitness category, rated 12+, for iPhone running iOS 17.2 or later; the current version is 1.5.1, released 14 October 2026 (App Store listing, Oct 2026). It is sold by subscription only, at $12.99 per month or $49.99 per year in USD, with no free trial and one tier. Excerpts from its App Store reviews, chosen by a stated policy, are on the Pepti reviews page.
It is not a medical device, and it is not a source of dosing information: no screen in the app and no page on this site suggests, recommends or adjusts a dose. It is not a pharmacy, a clinic or a supplier, and it sells no compounds. It is not a social product: there is no account, no feed and no community. And it is not a general health app that happens to allow injections; it was built around the specific records of vials, injections and injection sites.
The editorial and citation standard
Every statement on this site about what a compound is, how it acts, how long it lasts or what a trial found is tied to a source we fetched: a PubMed abstract or open-access full text, or a current product label on DailyMed or the FDA’s site. Trial claims name the first author, journal and year, and link to the paper. Sources headings count their links, and the count is checked. Half-lives are stated only where a human study or a label reports one; where none has been published, the page says so rather than printing a number. Competitor facts come from the other app’s own pages and carry the month they were read. The full rules, including what we refuse to publish and the corrections we have made, are in the editorial policy. The site was last audited against those rules in full in October 2026: every PubMed link and every cited statistic was checked, and all matched their sources.
How this site is funded
By app subscriptions, and nothing else. The site carries no advertising, no affiliate links and no sponsored placements, and the comparison pages are not paid for by anyone they name. The one commercial interest on every page is the obvious one: we make the app the pages describe, and we say so at the top of each one.
