Pepti vs Dose Track: which peptide tracker fits you?

By Tessaro Pty Ltd, the maker of Pepti · Reviewed September 2026

This comparison is written by the maker of Pepti, one of the two apps. The Dose Track facts below come from its public website and App Store listing as read in September 2026; products change, so verify current details on Dose Track's own pages. We have credited Dose Track for what it does better than us and stated our own limits plainly. A comparison written by one side is not neutral by default, so we have tried to make ours checkable: every Dose Track claim is dated and points to a public page you can open yourself, and where we could not verify something — the Pro price, for instance — we have said so rather than guess.

The comparison

Where Dose Track is stronger

Dose Track's core is free (Sep 2026), so you can begin tracking without paying, and it ships on both iOS and Android, which settles the choice immediately if you are not on an iPhone. Its standout feature is breadth of built-in data: its site describes a database of 600+ compounds with pre-set pharmacokinetic parameters (Sep 2026), which means the app already knows the half-life and Tmax for what you are tracking and you do not have to enter them by hand. Those Tmax-aware parameters feed level curves that model not just how a compound clears but when it peaks. It also offers AI-assisted parsing of bloodwork PDFs, stated as on-device OCR (Sep 2026), turning a lab report into structured data without retyping. If a large pre-built database and richer modelling are what you want, Dose Track is the stronger tool and we will say so.

The pre-set database in particular removes a step that trips people up in every tracker: getting a compound's parameters right in the first place. When the app supplies them, the curves are consistent from the start rather than depending on what you happened to type, and that is a real convenience for anyone running several compounds at once.

Where Pepti is stronger

Pepti's evidence pages cite their sources with PubMed links and honest counts rather than assertions, so a claim on the page can be checked at its origin. It holds a strict no-dosing-information design: neither the app nor the site provides dosing information of any kind — you supply a figure you already have and Pepti does the arithmetic. Its pricing is a single flat tier with nothing gated behind a Pro upgrade, so the feature you read about is the feature you get. And this comparison itself is written by a maker that does not rank itself first: we have led with where Dose Track is stronger because on several axes it is.

On data handling, Pepti offers no account, no sign-up and no cloud sync, and your protocol and health data stay on the device — with one honest exception we state plainly: the optional AI coach sends that conversation to Pepti's server to answer. Open the coach and only that exchange is sent; leave it unused and your data stays on the phone. We would rather name the exception than round it off.

Where they are close

On the axis people most often ask about — where your data lives — these two are closer than the rest of the field. Both keep protocol data on the device: Dose Track states all health data stays on-device with no server-side collection (Sep 2026), and Pepti keeps data local apart from the optional coach conversation described above. Both include a reconstitution calculator and injection-site rotation. So this axis alone will not separate them; the decision comes down to price, platform, database breadth, and whether you want cited evidence or built-in tracking-and-education content.

Who should pick which

There is no single winner here, only a fit. In short:

For the wider field, see how Pepti compares to other trackers, read the head-to-head with Pepti vs Regimen, try the free reconstitution calculator, or read about the Pepti peptide tracker.

Both apps are actively maintained and both do the core job well. If this page has done its work, it has narrowed the choice to what actually divides them: a free, database-rich, cross-platform tool with built-in tracking content, or a paid, iOS-only, measurement-only tool with cited evidence and no dosing information.

Common questions

Is Dose Track free?

Dose Track is free to start (Sep 2026). An optional Pro tier unlocks unlimited compounds, pharmacokinetic charts and bloodwork analysis; the Pro price was not verified on the pages we reviewed, so check Dose Track's own listing for the current figure.

Does Pepti keep data on the device?

Mostly. Pepti has no account, no sign-up and no cloud sync, and your protocol and health data stay on the device — with one exception: if you choose to use the optional AI coach, that conversation is sent to Pepti's server to generate a reply. Everything else stays local.

Which has more compounds?

Dose Track, by its own account: its site describes a built-in database of 600+ compounds with pre-set pharmacokinetic parameters (Sep 2026). Pepti ships a smaller, evidence-focused set of compound pages rather than a large database.

Does either provide dosing information?

Pepti does not, anywhere, by design: you enter a figure you already have and it does the arithmetic. Dose Track's own disclaimer states that dosing information is provided for educational and tracking purposes (Sep 2026). Neither app's content is medical advice.

Can I use Pepti on Android?

No. Pepti is iOS only, requiring iOS 17.2 or later. If you are on Android, Dose Track ships an Android app and is the option to look at.

Not medical advice. Pepti is a record-keeping and measurement tool, not a medical device.
