Pepti vs Dose Track: which peptide tracker fits you?

By Tessaro Pty Ltd, the maker of Pepti · Reviewed October 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, with its price and platforms re-checked in October 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 we have said so rather than guess.

Where Dose Track is stronger

Dose Track's core is free (Oct 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 bloodwork reading from a PDF or photo, which its site says is processed by Google Gemini and not stored (Oct 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 records it. 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 two opt-in exceptions we state plainly: the AI coach and lab-report import, both behind one consent switch. Turn them on and 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; leave them off and your protocol and health 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 health records stay on the phone by default, leaving only for AI answers, lab reading or an optional encrypted backup (Oct 2026), and Pepti keeps protocol and health data local apart from the opt-in AI features described above. Both include injection-site rotation; Dose Track also includes a reconstitution calculator, which Pepti removed from the app in October 2026. 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, learn what a peptide tracking app does, 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 record-keeping tool with cited evidence and no dosing information.

Common questions

Is Dose Track free?

Dose Track is free to start (Oct 2026). An optional Pro tier unlocks unlimited compounds, pharmacokinetic charts and bloodwork analysis; its website and App Store listing show Pro at $6.99 a month or $69.99 a year (Oct 2026). 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 — unless you turn on the AI coach or lab-report import, both behind one consent switch. 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.

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 logs it. 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 tool, not a medical device.
