The Best TRT & Peptide Tracking Apps in 2026

I built one of these apps, so take this with that bias in mind, but here is an honest, fact-checked look at six real competitors, what each one does, and exactly where Frontload fits and where it doesn't.

I built Frontload because I wanted one app that tracked everything I actually needed, for me: my inventory (what I’m taking, how much I have left), injection sites, and reminders for my shots, without paying around $9 a month for the privilege, which is what most of the other apps in this category charge for just the basics. So yes, I have a bias writing this list. Here’s the honest version anyway.

Quick answer

Judge a peptide or TRT tracker on four things: does it model blood levels, is the AI (if it has one) grounded in your own logged data instead of generic answers, is core tracking free or paywalled, and what does it do with your data. Among real competitors, PeptidePal and Pep AI have the deepest track record by review volume, and Injectly stands out for pairing genuine privacy with its own blood-level projections. Frontload's honest edge is free core tracking with no account, plus an AI coach tested with an automated eval suite before every update, not being the single most-reviewed app in the category yet.

What actually matters in a peptide or TRT tracker

Most of these apps look similar in a screenshot: a calendar, a compound list, a chat bubble labeled “AI.” The differences that matter show up after a few weeks of real use:

Blood-level modeling. Does it show a real pharmacokinetic curve (peak, trough, the shape between doses) or just a static list of what you logged?
Compound-grounded AI, not a generic wrapper. Is the assistant reading your actual logged doses and labs, or answering from general web knowledge with your data bolted on as context?
What's free vs. paywalled. Some trackers put basic logging behind a subscription. Calculators and tracking are safety tools, not premium conveniences.
Privacy. Is your health data linked to your identity, sold, or used for cross-app tracking? Check the App Store privacy label, not just the marketing copy.

Six real apps, compared

Here is what six current, real competitors offer, pulled from their App Store listings on November 10, 2026. Ratings and review counts are a snapshot. Check the current listing before deciding. One change worth knowing: in late October 2026, PeptidePal, Regimen, Peptide Tracker, and Injectly all removed their dose or reconstitution calculators, each citing App Store rules, so if calculators matter to you, check what the current version still does.

Method, and the obvious conflict

One of these apps is mine. That is stated above and it is worth repeating here, because a roundup written by a competitor is exactly the kind of source this site tells you to be suspicious of. Read it as an informed and interested account, not a neutral survey.
Ratings and review counts are a snapshot taken from each app's store listing on the date of writing. They move, and a small app's average can swing on a handful of reviews, so treat them as a rough signal rather than a ranking.
Feature comparisons come from each app's public store listing. Where a feature exists but is not described there, a roundup will tend to miss it: that has happened to Frontload, where a third-party comparison marked injection-site rotation as absent when it has been built the whole time. The same error is possible in the other direction here.

App Store ratings count (Nov 10, 2026)

App Store ratings count per app as of Nov 10, 2026, a rough proxy for how established each one is. Frontload and Dose Track are not shown: Frontload launched in June 2026 and sits at 62 ratings, Dose Track has 25, and both are far too few to belong on this scale. A 4.98 on 62 ratings carries much less weight than a 4.7 on nearly five thousand.

The six apps, one at a time

Pep AI: GLP-1 Tracker App (Zode Development)

The second most-reviewed app on this list, and the listing has narrowed to GLP-1s: Ozempic, Wegovy, Mounjaro, Zepbound, compounded semaglutide and tirzepatide, and the oral GLP-1s. It plays like an all-in-one organizer: dose schedules and reminders, an injection-site body map, side-effect logging shown next to your dose history, food logging with menu and meal-photo scans, hydration, weight, progress photos, and PDF reports for your provider. It shows estimated medication levels, labeled as estimates only. Best for someone on a GLP-1 who wants shots, food, and side effects in one place. Honest caveats: it is free to download but you need a subscription to use the tracking features, the listing no longer mentions a reconstitution calculator (it says the app does not calculate doses), and if you run peptides beyond GLP-1s, the listing does not speak to them.

PeptidePal (Blank Labs)

The most-reviewed app on this list, and it says it is used by over 150,000 people. It spans GLP-1s, research peptides, and TRT with a protocol builder (mcg/mg/IU/mL, cycles, on/off weeks), one-tap dose logging, vial inventory with run-out projections, an injection-site body map, a compound library (the listing says 110+ in one place and 50+ in another), nutrition tracking, progress photos with compare and time-lapse, and an estimated on-board level curve it calls an educational estimate, not a measurement. Its AI advisor answers educational questions and will not recommend a dose or protocol. Best for someone who wants breadth across compound categories plus a moderated peer forum. Honest caveats: the free tier is gone. Protocol tracking, the full library, analytics, and AI chat now require a subscription, and the October 2026 update removed the calculator features to stay compliant with Apple.

Regimen: Peptide Tracker (Awaken Labs)

Covers TRT, HRT, GLP-1s, and a 200+ compound library, with custom scheduling, dose titration you can plan in advance, vial tracking with low-stock alerts, bloodwork logging, progress photos, Apple Health sync, and hour-by-hour half-life plotting of compound levels. Its actual angle is still connecting your doses to your health metrics and response, flagging patterns against your own baseline, not just logging that you took something. Best for someone who wants that response-tracking angle specifically. Honest caveats: the first compound is free with no time limit, but more compounds and the advanced features need Premium, listed at $7.99/mo or $49.99/yr after a 14-day trial, and the October 2026 update removed the reconstitution calculators from the iOS app to meet App Store requirements.

Peptide Tracker Log & Reminder (Flat Six Labs)

Still the free all-rounder, and it says it is used by over 100,000 people: protocol and stack builder, dose logging with automatic inventory updates, vial inventory (remaining volume, blend components, bacteriostatic water), a body-weight trend, progress photos with alignment tools and side-by-side compare, Apple Health in a "Pulse" timeline next to your doses, an estimated plasma level curve per compound, and a community of people on the same compounds. Best for someone who wants a full feature set with nothing behind a paywall. Honest caveats: as of version 3.1.0 it no longer calculates doses or draws, you enter the draw yourself, and its "Peptide Assistant" is described as general peptide information, not as something that reads your logged data.

Injectly (Matthias Gattermeier)

The privacy-first standout: free, no ads, no subscription, and no tracking, with logging, reminders, and a calendar history, and no account needed for any of it. An optional free Apple or Google account adds cross-device sync and advanced scheduling like on/off cycles. For supported medications, its "Insights" tab projects current and peak serum concentration from your logged doses and weight, which, fairly, overlaps directly with the blood-level modeling Frontload leads with. Best for someone who wants a private, no-account tracker that still models blood levels. Honest caveats: it is a solo-developer app, so expect a smaller feature surface than the bigger apps here, and the November 2026 update removed the syringe-unit calculation to comply with App Store rules.

Peptides & GLP-1: Dose Track (Ethen Amezquita)

The newest and smallest app on this list: on the App Store since December 2025, with 25 ratings there and 48 on Google Play, and it is on both iOS and Android. The listing covers GLP-1s, TRT, and peptides with a library of 800+ medications and supplements, each on its own schedule, one-tap logging of every dose that is due, injection-site rotation with a history of every site, and vial and pen inventory that shows how much is left, when it runs out, and when to reorder based on how long your supplier takes to deliver. It also has a labs section (each marker against its range, grouped by body system, with history), vitals from Apple Health or Health Connect shown next to your doses, an estimated active-level readout it calls an estimate, not a lab result, a "Pulse" briefing and chat that it says reads your own logs, and a community. Best for someone running several compounds who wants inventory and reorder timing in one place. Honest caveats: the track record is thin at 25 App Store ratings, its site lists Pro at $24.99/mo or $129.99/yr while the App Store in-app purchase list also shows $6.99/mo and $69.99/yr tiers, unlimited medications, the Levels chart, Pulse, and the injection-site map are all listed under Pro, and the Google Play listing still describes a reconstitution calculator while the current iOS listing does not mention one.

How to evaluate the AI, not just the pitch

Almost every app in this category now claims its AI is “grounded” or “accurate.” That is a marketing sentence, not proof. Ask what happens when you ask a question the app can't answer from your data: does it guess, or does it say so? Ask if there is any published testing process, not just a feature list. Try the free tier and see how it handles being wrong before you subscribe to any of them.

Where Frontload fits, and where it doesn't

Frontload fits if you want free core tracking: inventory, protocols, the injection calendar, dose/blend/half-life calculators, the blood-level PK chart, progress photos, health sync, and full data export, all free with no account and no time limit, plus a privacy posture with no analytics SDKs. The Pro tier adds the AI Coach, PDF/photo lab parsing, Cloud Backup, and the web dashboard on top of that free base; it doesn't gate the tracking itself.

A few things have landed since I first wrote this. Progress Photos, under More, is free: a voice-guided camera that lines you up the same way every time, a hands-free Auto run that calls out each pose, and a compare view for any two photos. With Pro, Full physique review sends your latest session to the coach and you get a body-fat range and which areas are lagging. Body Scans can import a DEXA or smart-scale report from a PDF or photo (also Pro). Cloud Backup and the web dashboard at app.frontloadapp.com are part of Pro, and not part of the free trial. On the free side: set a protocol's start date and Frontload offers to fill in the doses you took before you installed it, food you log in other apps comes in from Apple Health or Health Connect with protein, carbs, fat, and fiber, and Try a different schedule under the Blood Levels chart shows how your levels would look on another cadence without changing anything.

The honest gaps. It launched in June 2026 and has 62 ratings, so the track record is thin next to PeptidePal or Pep AI, and it is a one-person project. The photo body-fat read is an estimate, not a measurement: the coach gives a range, never a single number, and says plainly that general AI vision models have no published validation for body-fat estimation. There is no community or forum like PeptidePal, Peptide Tracker, and Dose Track have. And on blood-level modeling it isn't alone anymore: Injectly projects serum concentration for free with no account, and PeptidePal, Regimen, Peptide Tracker, Pep AI, and Dose Track all now list some form of estimated level curve. Frontload's difference there is a chart in real units tied to the same PK engine used across the whole app, plus a coach that reads that data directly, not exclusivity on the underlying idea. Those are honest gaps and an honest overlap, not reasons to pretend otherwise.

Why I built this one

The scope kept growing on me. I started with what I wanted most: track my inventory, my injection sites, and get reminders for my shots. Then titration got added, then supplements and medications, then TRT itself, since I started TRT while I was building this. I have a WHOOP and track nutrition with MacroFactor, so those got pulled in too. What I kept running into the whole time was that there was nowhere to put all of it in one place and have it feed a curated AI that actually gave advice based on my real data, instead of me pasting pieces of it into ChatGPT one at a time and getting back a generic answer I’d have to correct myself: “no, I train five days a week,” “my diet is this many calories.” Now the AI already knows everything I’m doing. That’s the actual reason this app exists, and it’s the lens I’m comparing everything else through.

Frequently asked questions

Which app in this category is actually the most established?

By review volume, PeptidePal (4,924 ratings), Pep AI (4,021), and Peptide Tracker (3,006) currently have the deepest track record in the field, as of Nov 10, 2026. Ratings and review counts move over time, so check each app’s current App Store listing rather than trusting a snapshot from this post.

Do I have to pay to track my protocol?

It depends on the app. Pep AI and PeptidePal both require a subscription to use their tracking features. Peptide Tracker and Injectly are free. Regimen is free for one compound, with Premium unlocking the rest, and Dose Track puts unlimited medications, its Levels chart, and its Pulse assistant under Pro. In Frontload, tracking is free with no account and no time limit. Pro adds the AI Coach, PDF/photo lab and body-scan parsing, label scans, Cloud Backup, and the web dashboard on top of that.

What actually makes an AI coach trustworthy, not just "AI-powered"?

Whether it is grounded in your own logged data instead of generic web answers, whether it is built to say "I don’t know" rather than guess, and whether the people building it can show you a real testing process for catching wrong answers before they ship, not just a claim that it is accurate. Frontload runs an automated eval suite against known failure modes before every update; ask any tracker you are considering what theirs looks like.

Does Frontload sell or share my data?

No. There is no analytics SDK in the app, no cross-app tracking, and your data is never sold. You don't need an account. If you turn on Cloud Backup, it's tied to your email address so you can restore it. Full posture is on the privacy page.

Which app should I actually pick?

It depends what you’re optimizing for. Want the deepest review history behind the app? PeptidePal or Pep AI, both paid. Want a fully private, no-account app that also models blood levels? Injectly is the closest match to that combination. Want free core tracking, a PK chart in real units, and an AI coach tested with an automated eval suite before every update? That’s the case for Frontload. Peptide Tracker, Injectly, and Frontload are free to actually use, and Regimen is free for one compound. Trying the actual app beats trusting any comparison post, including this one.
