Best peptide tracker apps for privacy in 2026: which ones need an account?

By Tessaro Pty Ltd, the maker of Pepti · Last reviewed October 2026

This page is written by the maker of Pepti, one of the ten apps compared; the others were reviewed from their public websites, App Store and Google Play listings and published policies in September 2026 (the account-and-data table below was refreshed October 2026), and which one is best genuinely depends on what you need. We have tried to write the version of this page we would want to read if we were choosing: competitors credited for what they do better than us, our own price and platform limits stated plainly rather than buried, and every claim about someone else's product tied to a date and a public source you can check yourself.

Which trackers need an account — and where your data lives

The sharpest privacy question when choosing a peptide tracker is plain: does it make you create an account, and where does your data actually sit? The table below answers that for the eight most-asked-about apps, next to whether each publishes dosing guidance, the platforms it runs on, and what it costs. Every fact was read in October 2026 from each app's own website or App Store listing; sources follow the table, and anything an app does not state we mark “not stated” rather than guess.

Account, data, dosing, platform and price facts above read from each app's own site/App Store, October 2026. “Not stated” means the app's own pages do not say.

Features and stance

The three things that actually differ

Feature lists across these apps converge more than the marketing suggests. All of them log a dose and keep vial records, and most of them do reconstitution arithmetic in the app (Pepti and Shotsy do not). If you compare them feature by feature you will conclude they are broadly interchangeable, and for day-to-day logging that is close to true. The differences that will actually affect you sit in three places, and none of them appear on a feature grid.

The first is where your protocol lives. An account-based app keeps a copy on a server, protected by a privacy policy, which is a promise a company makes and can revise. A device-only app has no copy to protect. Both are legitimate designs with different failure modes: a server can be breached or a policy can change, while a lost phone with no backup loses the record entirely.

The second is how the app is paid for. Subscription apps are paid by users. A free app is paid by something else, and the honest ones say what in their privacy policy. Neither arrangement is disqualifying, but they point the product in different directions over time, and it is worth knowing which one you are in.

The third is what the app is willing to tell you. Some of these products publish dosing content; some do not. That is an editorial position rather than a feature, and it is the one we hold most strongly, for reasons set out below.

Regimen

Regimen runs the largest content operation in this niche by a wide margin, and that is not a small thing: if you want to read your way into a topic before you track it, there is more there than anywhere else, across more languages. The app itself is genuinely free for one compound, which makes it the easiest way to start multi-compound tracking without paying up front, and it ships on both iOS and Android.

Two things to know before you commit. It is account-based, so your protocol lives on a server under a privacy policy rather than only on your phone. And as of October 2026 the premium price is still not displayed on its website, though its App Store listing now shows Premium at $7.99 and Premium Annual at $49.99. If you like to know the price before signing up, check the listing rather than the site.

Its content is also structured for finding rather than browsing: dedicated pages per compound, per medication class and per country, published across many languages (Sep 2026). If you want to read about a specific compound before tracking it, that structure is a genuine advantage over every other app here, ours included. We would rather say that plainly than pretend our smaller library competes on breadth.

Peptide Tracker

Peptide Tracker, by Flat Six Labs, is the one we would point you to if cost is your constraint. Its website states plainly that it is free with no subscription and no paywall, and the feature set is not a stripped demo: dose logging, vial inventory, plasma level estimates and the compound library are all included. Its compound pages carry real literature citations, PubMed and DOI links rather than assertions, which is rarer in this category than it should be. Its web calculator also handles premixed vials as well as powder, which several tools do not.

The trade is stated in its own privacy policy, and we credit it for stating it: the app earns commissions from health-product partner offers, including from suppliers, and those offers are personalised using what you track, including the compounds and protocols in your account. The policy says this is opt-in, that opting out is one tap, and that health readings are excluded from the targeting. Whether that is a fair exchange for a free full-featured tracker is a judgment only you can make, and it is the exact judgment we would want made consciously. Its compound pages also carry dosing sections, which is an editorial choice we have made differently.

PeptidePal (Blank Labs LLC)

PeptidePal is under visibly active development: its App Store version history shows a steady release cadence rather than an app shipped once and left alone, which is worth something in a category where abandoned trackers are common (Sep 2026). Its listing describes protocol data as held on the device, and it states that its calculator performs unit conversion only and does not recommend a dose. That last point is the same line we draw, and we will credit a competitor for drawing it rather than pretend we are alone in it.

Two things to weigh. It has accounts, with sign-in through Apple or Google and in-app deletion, though its pages do not say whether one is required, and its Apple privacy label lists health data and identifiers as collected and linked to your identity, which is a different posture from the on-device claim and worth reading together rather than separately (Sep 2026). Pricing is also spread across multiple price points, from $9.99 to $59.99 across monthly, quarterly and yearly options on its US App Store listing (Oct 2026), rather than published as a single figure, so what you pay depends on which option you land on.

Pepti

Pepti has no free tier and is iOS only. Every other app in the first table on this page is a free download with in-app purchases; Pepti is $12.99 a month or $49.99 a year. On monthly, that is above the entry purchase of six of the seven. On annual, $49.99 is at or below the top purchase listed for every one of them. App Store price ranges don't say what each purchase buys, so treat that as a rough guide, not a ranking. No free tier and iOS only are real disadvantages and we won't write around them: if you're on Android, or price decides it, one of the apps above is the better fit.

What the price buys is a different architecture rather than a longer feature list. Pepti has no account, and unless you turn on the AI coach or lab-report import, both behind one consent switch, your protocol stays on your phone: not anonymised in our analytics, not held under a policy that could change. That distinction only matters if it matters to you, and for a lot of people it will not. Alongside it: a 12-site injection site rotation system, a record for each vial with its lot, reconstitution and expiry dates, bloodwork reading against published reference ranges, and evidence pages for retatrutide, semaglutide and tirzepatide that cite their sources and count them honestly. And a strict design rule: no dosing guidance anywhere, on any page, for any compound. We record the figures you already have. We never supply the figure.

Dose Track

Dose Track, by Ethen Amezquita, is the free-to-start option with the most built-in modelling. Its site describes pharmacokinetic-grade tracking with level charts modelled against half-life and Tmax, and a database of 600+ compounds carrying preset PK parameters, so the curves are populated without manual entry (Sep 2026). It runs on iOS 15.5+ and Android (Oct 2026), includes a reconstitution calculator and automatic site rotation, and states that health records stay on the phone by default, leaving only for AI answers, lab reading or an optional encrypted backup (Oct 2026). It launched in December 2025 per its own site.

The core is free; a Pro tier unlocks unlimited compounds, pharmacokinetic charts and bloodwork analysis, at $6.99 a month or $69.99 a year on its site and App Store listing (Oct 2026). Its site disclaimer states that dosing information is provided for educational and tracking purposes (Sep 2026) — an editorial choice we have made differently, since Pepti publishes none. On breadth of preset data, it is the strongest free option here.

Shotsy

Shotsy, by Shotsy Co., is the pick for branded GLP-1 pens and pills. It calls itself the all-in-one GLP-1 medication tracker for weight-loss injections and pills, runs on iOS and Android, and shows estimated medication levels over time from charts based on peer-reviewed clinical data (Sep 2026). It offers a visual injection-site rotation map, and states a privacy-first design: data stored on the device and synced via Apple’s private iCloud, with a stated commitment that it never sells your data (Sep 2026).

The honest fit line: Shotsy is excellent for branded pens and pills, but it has no reconstitution calculator (Sep 2026) — it is built for pre-filled products, not compounded vials — so anyone reconstituting from powder needs a calculator for that math; Pepti has no in-app calculator either, and the free calculator on this site does it. It is free to download and freemium; its site lists no price, while its App Store listing shows $9.99–$19.99 a month and $39.99–$59.99 a year (Oct 2026).

PeptIQ

PeptIQ, by Kris Chase, is one of the most cross-platform options in this list: iOS, Android and web (Oct 2026). It describes itself as a privacy-first app to log and optimize peptide protocols, with education — not medical advice — as an explicit stance (Sep 2026). It carries a reconstitution calculator, a body-map site rotation, and a half-life visualization, and its copy says data can be private and on-device or synced across devices, an optional cloud-sync mode (Sep 2026).

It is free to download, but its pricing page says there is no free plan and full app access requires Premium; in-app purchases are listed from $9.99 to $129.99 on its App Store listing (Oct 2026). Its FAQ says no account is required for basic use (Oct 2026). If web access alongside a phone matters to you, PeptIQ and Peptide Tracker both offer a web app (Oct 2026).

PepTracker

PepTracker: Dose Log, by Jayven Alan Villagomez Peredo, is a dose log and protocol tracker built for peptides, GLP-1 medications and testosterone (its words). It includes a reconstitution calculator that turns vial amount, diluent and target dose into millilitres or syringe units (Sep 2026), and it is freemium: Premium is $4.99 a month or $47.99 a year on its App Store listing, its site shows $4.99 a month with no free trial, and the free tier is limited to two protocols (Oct 2026). LynkDose's listing also shows a $4.99 monthly option, plus a $2.99 weekly one (Oct 2026).

Two limits to note. It is Apple-only — its listing covers iPhone (iOS 18 or later) and Apple Vision, and while its site markets cloud sync, no Google Play or web listing was found (Oct 2026). It does not offer injection-site rotation: a developer reply on its listing acknowledges the feature as not yet built (Sep 2026). It makes no on-device privacy claim, and an account requirement is not stated on the pages reviewed (Sep 2026).

Smart Peptide Tracker

Smart Peptide Tracker, by Sean Hussain, positions itself as an all-in-one research companion for managing supplement inventory, scheduling routines and tracking progress (its words). It runs on iOS and Android (Oct 2026), and includes a reconstitution calculator plus a front-and-back body map that auto-suggests your next site for balanced rotation (Sep 2026).

It is freemium — Progress Tracking and Stack Analyzer are Premium (Sep 2026) — and its App Store listing shows in-app purchases from $4.99 to $54.99, including lifetime options (Oct 2026). Half-life or level charts are not stated on the pages reviewed, and no on-device or account statement was found on its first-party pages (Sep 2026). Its inventory and scheduling depth is the strength; its data-handling posture is simply undocumented from the outside.

LynkDose

LynkDose, by Bashir Murtaza, is an all-in-one peptide tracker for iPhone that markets itself as all private and local-first (Sep 2026). It carries a reconstitution calculator that converts vial amount, BAC water and target dose into draw volumes and syringe units, plus injection-site rotation (Sep 2026). Of the ten apps here, its local-first positioning is the closest to Pepti’s.

Where it differs from Pepti: LynkDose’s focus is linking every dose to your biometrics, while Pepti’s is cited evidence pages and a strict no-dosing design. Two caveats on the privacy claim: the local-first wording appears on its site, the App Store listing itself does not state it, and an account requirement is not stated on the pages reviewed (Sep 2026). It is Apple-only (iPhone on iOS 26 or later, plus Mac and Apple Vision) and free to download, with in-app purchases from $2.99 weekly to $39.99 yearly and a 7-day free trial stated on its site (Oct 2026).

Which one should you use

What this comparison cannot tell you

Only one of these ten apps was used from the inside, and it is ours. Everything said about the others comes from what they publish about themselves, which means this page compares public positioning, pricing, policies and editorial stance rather than the experience of actually living with each app for a month. Feature depth, reliability, how the interfaces feel under daily use, how quickly support answers, and whether the reminders fire when they should are all invisible from here.

That matters because those things often decide which app you keep. A tracker with the architecture you prefer and an interface you avoid opening is worse than one you actually use. Our advice is to treat this page as a shortlist rather than a verdict: it should narrow the field to one or two on the criteria you can only check from outside. Install the finalists that are free to start, and for Pepti read the comparison pages above before you pay; the one you still open a fortnight later is the answer.

Methods: the competing apps were reviewed from public first-party sources in September 2026, and every app’s price model and platforms were re-checked in October 2026 — their own websites, App Store and Google Play listings, and published privacy policies. The six apps added in this expansion — Dose Track, Shotsy, PeptIQ, PepTracker, Smart Peptide Tracker and LynkDose — were verified the same way, and any detail we could not confirm is marked “not stated on the pages reviewed” rather than guessed. No app was reviewed from inside except Pepti, which is ours; the one exception is PeptidePal - Peptide Tracker by Blank Labs LLC (App Store id6762102880), whose paywall was also observed in-app. Several unrelated apps share the PeptidePal name, and that listing is the one compared here. Prices, policies and content change, and everything here is a snapshot of that date. Corrections are welcome at support@tessaro.com.au and we will amend this page.

Common questions

What is the best peptide tracker app?

There is no single best one; it depends on the trade-off that matters most to you. For free tracking, Peptide Tracker by Flat Six Labs states it is free with no subscription, and Regimen is free for one compound (October 2026). On Android, seven of the ten apps here have Google Play listings (October 2026). For branded pens and pills, Shotsy is built for them. For compounded vials with no account and no cloud sync, Pepti keeps protocol and health data on the iPhone unless you turn on the AI coach or lab-report import; it is paid, at US$12.99 a month or US$49.99 a year (October 2026).

Which peptide tracker is free?

Peptide Tracker by Flat Six Labs states on its website that it is free with no subscription and no paywall, with an optional Founding Member membership (verified October 2026). Regimen is free to use for one compound, with a premium tier for multi-compound tracking whose price is not displayed on its website; its App Store listing shows Premium at $7.99 and Premium Annual at $49.99 (October 2026). Pepti is paid, and PeptidePal is free to download but showed a paywall in-app (September 2026). Most of the ten apps here are free to download with paid tiers on top: Dose Track, Shotsy, PepTracker and Smart Peptide Tracker list a free entry point with a paid upgrade, LynkDose states a 7-day free trial, and PeptIQ is free to download but states it has no free plan (October 2026). If cost is the binding constraint, the free option is the honest answer, and it is not the one we sell.

Which peptide tracker is most private?

Pepti, by construction rather than by policy. It has no account, and your protocol stays on the device unless you turn on the AI coach or lab-report import, both behind one consent switch; with those off, nothing about it is held server-side for anyone to lose, sell or hand over. Several others also keep data on the device by default; those that are account-based or sync server-side make their commitments in the form of privacy policies, which are promises about what a company will do with data it holds. Both models can be run well. They fail differently.

Do any of these apps tell you what dose to take?

Pepti does not, anywhere, by design: it records figures you already have and supplies none of its own. On the websites we reviewed in September 2026, Regimen publishes dose and titration guides, and Peptide Tracker publishes a dosing section on each compound page. We think that is the wrong call for compounds without an approved label, but it is a real difference in editorial policy rather than a defect, and you should decide which you want.

Is Pepti worth $12.99 a month?

Only if two specific things matter to you: that your protocol stays on the device unless you turn on the AI coach or lab-report import, and that site rotation, vial records and reminders are built in rather than kept by hand. If neither is worth paying for, or if price is the constraint, use the free option instead. It tracks doses perfectly well. We would rather you used a tracker that fits than paid us out of inertia.

Does Pepti work on Android?

No. Pepti is iOS only, requiring iOS 17.2 or later. If you are on Android, Regimen, Peptide Tracker, Shotsy, Dose Track, PeptIQ, PeptidePal and Smart Peptide Tracker all have Android apps on Google Play (October 2026).

How were these apps compared?

From public sources in September 2026, with prices and platforms re-checked in October 2026: each app's own website, its App Store and Google Play listings, and its published privacy policy. Only Pepti was reviewed from the inside, because it is ours. That is a real limitation: it means feature depth inside the other apps is not assessed here, only what they state publicly. Corrections are welcome at support@tessaro.com.au.

Do peptide tracker apps do reconstitution math?

Most of the ten apps on this page do. Regimen, Peptide Tracker, PeptidePal, Dose Track, PeptIQ, PepTracker, Smart Peptide Tracker and LynkDose each list a reconstitution calculator. Pepti removed its in-app calculator in October 2026 (the free calculator on this site remains), and Shotsy does not have one, because it is built for pens and pills. Each entry was checked on the app's own pages in September or October 2026; the Features and stance table has the detail.

Can I track GLP-1s and peptides in the same app?

In Pepti, yes. A weekly GLP-1 and a daily research peptide can sit in the same log, each with its own schedule and vial, sharing one site rotation. Whether another app on this page does the same is something to check on its own pages; we have only recorded what each one states.

Do I need an app, or is a spreadsheet enough?

A spreadsheet is enough if your routine is simple and you keep it up, and we publish a free template. It will not remind you, rotate sites or link each injection to its vial, so those stay manual. An app earns its place when there are several vials, a rotation to keep and dates to track.

Is there a free spreadsheet that can track peptides?

Yes. This site publishes a free CSV template with the columns an injectable record needs: date, time, compound, the amount you were given, unit, vial id, lot, site and notes. It needs no sign-up and holds no figures of its own. It will not remind you, link each injection to its vial or remember which site is next, which is where the apps compared above earn their place.

This page compares tracking tools. It does not recommend any compound, dose, or schedule, and Pepti provides no dosing guidance on any page.

Pepti’s private peptide tracker keeps the log, the site sequence, the vial records and the weight trend on your phone, unless you turn on the AI coach or lab-report import.

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