The Best Peptide Tracker Apps in 2026: 24 Apps Compared

Disclosure, up front: We make LynkDose, one of the 24 apps below. That is a conflict of interest and you should read this with it in mind.

Here is how we have tried to handle it. We do not rank LynkDose first — we do not think it is the best app for most people, and its own section says plainly who it is and isn’t for, including the things it does not do. Every price, rating and feature here was verified against the App Store, Google Play or the developer’s own pricing page on 3 September 2026 (PepMinder, added later, on 16 October 2026), including for apps that beat ours. Where a competitor is better, we say so.

Credit where it is due: My Pep Calc does the same thing in their roundup and ranks themselves last, on the reasoning that leading with your own product destroys credibility. They are right.

Quick picks

How we evaluated

Peptide tracking has jobs that generic medication apps do badly:

1. Reconstitution math. You have a 10mg vial, you add 2ml of BAC water, you want 250mcg. How many units on a 100-unit insulin syringe? This is the most common and most consequential mistake in the category, and it is the main reason a notes app is not enough.
2. Vial lifecycle. When it was mixed, how much is left, when it expires, when to reorder.
3. Injection site rotation. Which sites you have used, and how long they have rested.
4. Adherence across a cycle. Peptides are usually run on/off. Did you actually run the protocol you intended?
5. Outcome correlation. Did it do anything measurable.

We checked all 24 against those, plus platform support, price, export and how much review volume stands behind the star average.

On star ratings. Several apps here show 4.9 or 5.0 on fewer than 25 reviews. That is not a meaningful number — one good week produces it. We print the rating count next to every average so you can weight it yourself.

The full comparison

US storefront prices as of 3 September 2026 (PepMinder: 16 October 2026, Google Play). Several developers run concurrent price tests, so what you are shown may differ — the specific cases are noted below.

The apps, in detail

Peptide Tracker (Log & Reminder) — the one to try first

Flat Six Labs LLC · 4.9 stars, 1,874 ratings · Free

This is the app we would point most people to before paying anyone, ourselves included.

It is genuinely free — not freemium, not a trial. There is no paywall. The only in-app purchases are voluntary "Founding Member" tips between $5 and $80. It launched in May 2026 and gathered roughly 1,900 ratings in four months, the strongest adoption signal here outside Shotsy.

Strengths: Reconstitution calculator in-app and free on the web. Vial inventory that distinguishes mixed from unmixed and tracks BAC water. Estimated plasma-level curves. Injection site rotation. Progress photos with alignment tools. A "Peptide Assistant" educational chat. A 25-lesson course and an anonymous community forum, neither of which anyone else here ships. iOS and Android.

Trade-offs: No Apple Health sync. Data export is "contact us at any time" rather than self-serve, which is a real limitation if you want your own history on demand.

Best for: Almost anyone starting out, and plenty of people who aren’t. Start here. Only pay for something else once you hit an actual wall.

Shotsy — the incumbent, if it tracks what you take

Shotsy Co. · 4.8 stars, ~31,000 ratings

Roughly seventeen times the review volume of the next-largest app here. Shipping since May 2024, 16 languages, and medication-level charts built on peer-reviewed clinical data for semaglutide, tirzepatide, liraglutide and dulaglutide.

The caveat that decides it: Shotsy is built for prescription GLP-1 pens — Ozempic, Wegovy, Mounjaro, Zepbound. It has no reconstitution calculator and no vial inventory, because pen users need neither. If you are reconstituting lyophilized powder, this is the wrong tool regardless of how good it is.

Pricing note: Shotsy runs at least five concurrent price points ($9.99, $14.99 and $19.99 monthly; $39.99 and $59.99 yearly) and publishes no price on its own site. What you are quoted depends on which test you land in.

PeptIQ — the most featureful, and the most expensive

Kris Chase · 4.7 stars, 609 ratings

The widest platform coverage here: iOS, Android and a full web app. Also the deepest integrations — Apple Health, Google Fit, Whoop and Oura, plus bloodwork from Quest, LabCorp and Function. AI Companion with research citations, protocol audit, vial scanner, doctor-notes scanner.

Trade-offs: No free plan at all. Monthly runs $19.99–$24.99, the highest here. Annual is $99 in-app against a discounted web price, though web discounts appear to be promotional rather than standing — check both at the moment you buy.

Privacy note: PeptIQ’s App Store label discloses identifiers used to track you across apps, and identifiers and user ID shared for third-party advertising. If on-device-only data handling matters to you, compare that against Peptide Tracker & Calculator and Protocol, both of which Apple labels as collecting nothing. (Our own label is not clean either — see our section.)

Peptide Tracker & Calculator — the best inventory, and a clean privacy label

David Dzeveckij · 4.8 stars, 509 ratings

The highest rating at meaningful volume, and the most thorough vial tracking we found: concentration, units, vial size, reconstitution liquid, mix date, storage temperature, source, batch number, expiration, and low-stock alerts.

Apple’s privacy label states, verbatim, "the developer does not collect any data from this app." Everything is local.

Trade-offs: Some reviewers report reminders not firing consistently and a text-based injection site picker rather than a body diagram. No way to plan future cycling schedules. Export is limited — bloodwork CSV import and progress photo export; we could not verify general dose-log export.

Best for: People whose priority is vial management, or whose data staying on their device is non-negotiable.

PepTracker: Dose Log — the best export story

Jayven Alan Villagomez Peredo · 4.7 stars, 437 ratings

CSV and PDF export plus Apple and Google Calendar sync — the most complete "get your data out" setup here. Explicitly covers peptides, GLP-1s and TRT.

Trade-offs: The free tier caps at three protocols. No injection site mapping. iPhone only — no iPad. Some reviewers report friction around logging doses retroactively. Support is separately and repeatedly praised as fast.

Regimen — the best-balanced paid app

Awaken Labs LLC · 4.8 stars, 375 ratings

The most honest free tier in this comparison: every feature, one compound, no time limit, no credit card. If you run a single compound you may never need to pay.

200+ compounds. Reconstitution plus split-dose, intranasal and TRT-oil calculators. Half-life plotting against published clinical-trial averages. 50+ daily markers. Apple Health. iOS and Android. $4.99/month or $39.99/year with a real 14-day trial.

Trade-offs: "Signals" is correlation analytics, not a chat assistant — if you want to ask questions in natural language, look elsewhere.

Best for: Most people who are going to pay for something. It is the app we would recommend over ours for multi-compound tracking, and the one we would recommend on Android without hesitation.

PeptideKit — solid, but check your iOS version

Jamal Baga · 4.7 stars, 301 ratings

AI chat assistant, inventory tracking, detailed journaling with dose associations, cross-device sync, export for sharing with providers.

Trade-offs: Requires iOS 18.6 or later, which excludes a lot of devices. No Apple Health integration. $9.99/month is high, though $69.99 lifetime is fair.

OptiPin — the most complete iOS-only option

Vitaloom LTD · 4.8 stars, 155 ratings

Free tier of one medication forever, no account or card. Pharmacokinetic forecasting for testosterone, estrogen, DHT and GLP-1. Granular injection site mapping. Daily journaling with mood, sleep, libido and energy. CSV export. On-device storage. Privacy-conscious reminders that keep the compound name off your lock screen.

Trade-offs: iOS only. No conversational AI — "Protocol Insights" produces summaries, not chat. There are "OptiInsight" credit packs ($0.99 and $4.99) in the App Store listing that the marketing site never explains.

Smart Peptide Tracker — buy it once

Sean Hussain · 4.7 stars, 146 ratings

No subscription. $34.99 lifetime, with optional add-ons. 100+ compounds and 27+ blend formulations, a cycle planner, multi-currency cost tracking, local storage with optional PIN encryption, and an unusual one: partner add-ons that let you track someone else’s protocol alongside your own.

Trade-offs: No Apple Health sync. AI is a metered question pack, not a real assistant. Export is JSON plus a health-report PDF — no CSV.

Best for: Anyone allergic to subscriptions, and couples tracking together.

Peptide AI: Stack Intelligence — evidence grading

Peptide AI LLC · 4.4 stars, 64 ratings

Grades peptides by research quality and tracks biomarkers alongside them. Camera-based body composition. Bloodwork and wearable data on one timeline. iOS and Android.

Trade-offs: $14.99/month is steep, though the discounted annual is competitive. No export stated.

Name warning: there is a second, unrelated app also called Peptide AI, from a different developer. Check the seller name before installing.

The Peptide App — outcomes over logging

The Peptide App LLC · 4.6 stars, 60 ratings

Everything unlocked from day one — no feature gating, just a time-based subscription. Goal-based peptide discovery, an expert-vetted library, progress photos with comparisons, COA filtering. Tracks weight, body fat, waist, sleep, energy, mood and recovery. Member rate of $4.99/month via invite code.

Trade-offs: No iPad. No data export. The injection site content is an instructional guide, not a tracked rotation map.

Dose Track — pharmacokinetics and lab OCR

Ethen Amezquita · 4.9 stars, 24 ratings

Plasma concentration charts across a large compound library, a dose simulator, bloodwork PDF OCR, and a "Pulse AI" protocol coach. Free tier covers one medication with full analytics. iCloud sync included.

Trade-offs: 24 ratings is a thin base. Android availability is ambiguous across the developer’s own surfaces — confirm before buying if that matters. No export stated.

Peptify — the most ambitious feature list

Dylan Capshaw · 4.2 stars, 21 ratings

A two-compartment pharmacokinetic engine with what-if dose scenarios. Bloodwork import via camera or PDF OCR across 80+ biomarkers. DEXA and InBody OCR. PubMed citations across 61 compounds with evidence-strength ratings. Multi-page PDF provider reports. Plus a community layer and a gamified 32-lesson education system. No account required, optional Face ID lock. $89.99 lifetime.

Trade-offs: The lowest average of any app here with more than 20 ratings. That much surface area on a solo-developer app raises a fair maintenance question.

PepMinder — private and Android-first

Tr8der_T · 4.8 stars, 17 ratings on Google Play · free tier, or Pro

An Android tracker that does the logistics well and keeps everything on the phone: no account, no cloud, and Google Play's data-safety label says it collects and shares nothing. Reconstitution calculator with a visual 30/50/100-unit syringe, reminders that work offline, vial supply that counts down as you log, expiry reminders for mixed vials, and dose steps over time that the reminders follow automatically. Weight tracking and progress photos sit alongside the log.

Trade-offs: The free version is tight — two peptides, 30 days of history, and ads — and several reviewers say they wish that had been clearer before installing. Export, backup and unlimited peptides are Pro only. No Health Connect sync, no AI, and site rotation is a "last used" log rather than a body map. Seventeen ratings is a thin base. Pro pricing ($4.99/month, $39.99/year or $49.99 once) is as stated by the developer; Google Play shows it only at checkout.

Best for: Android users who want a private, offline tracker and follow a dose plan that steps up over time.

LynkDose — ours, and who it is actually for

Bashir Murtaza · 4.6 stars, 16 ratings · $9.99/month or $40/year, 7-day trial

Sixteen ratings. Nearly every app above has more real-world validation than we do, and if review volume is how you pick software — a reasonable way to pick software — several of them are the better bet. We would rather say that here than have you find it out in week two.

What we think we do well:

• An AI assistant with your actual context. Our chat has your recent logs, current inventory, upcoming reminders and Apple Health metrics loaded, and it can take actions — log a dose, create a reminder, add inventory, write a journal entry. Several apps here have AI. Fewer have AI that can do things rather than answer things.
• Compliance scoring per compound. Scheduled versus completed doses, per compound, with an overall ring. If you run a 12-week protocol, this tells you whether you actually ran it.
• Journaling with real depth. Mood on a 1–10 scale plus energy, focus, pain, libido and anxiety, auto-correlated against same-day doses.
• Full inventory handling across unreconstituted, reconstituted and pre-mixed compounds, with expiration and low-stock alerts.

What we do not do, and where others beat us:

• No Android. Regimen, PeptIQ, Protocol, Peptide AI, PepMinder and Peptide Tracker all have it.
• No dose calculator in the app. Apple's App Review Guideline 1.4.2 required us to remove it in version 1.5.5 (why). The same calculator is free on our website, but nearly every app above still does the math in-app.
• No data export shipped. Protocol and PepTracker do CSV and PDF today. We do not, and that is the gap we hear about most.
• No iCloud sync. Your history lives on your device. Lose the phone, lose the history. Dose Track and PeptIQ sync.
• No home screen widgets and no Apple Watch app. Nobody here ships a Watch app, but the widget gap is ours alone.
• A high minimum iOS version, which excludes devices our competitors support.
• Our privacy label is not the cleanest here. Apple lists our app as using Location and Identifiers to track, via third-party SDKs we use for analytics and attribution. Peptide Tracker & Calculator and Protocol both carry a clean "no data collected" label. If that is your deciding factor, they are the honest answer and we are working on ours.

Best for: Someone on iPhone running several compounds who wants to ask questions about their own data in plain language, and who cares about adherence tracking specifically. If you need Android, exports, cloud backup, or the reassurance of thousands of reviews, take one of the apps above. If it does sound like you, try it free for 7 days.

BodyDex — peptides inside a full fitness tracker

Daniel Bobunov · 4.9 stars, 10 ratings

The only app here where peptide tracking sits inside a complete calorie, macro and workout tracker. AI photo food scanning, barcode lookup, restaurant menu analysis, workout logging. The peptide feature set — BAC calculator, site rotation, supply tracker, adherence — is free; the paywall sits on the nutrition AI side.

Trade-offs: Ten ratings. No mood tracking. $79.99/year is expensive if you only want the peptide half.

Protocol — the privacy and export pick

IMA, LLC · 5.0 stars, 9 ratings

Explicit CSV and PDF export. An interactive 3D body map showing front and back at once, color-coded by rested, recent, today and never-used. Six AI tools metered by credits. Two-way Apple Health — it reads steps, sleep and heart rate, and writes weight, measurements and mindfulness sessions. Peptides, supplements and habits in one protocol under a single adherence score. No account, no cloud sync, everything local, "Data Not Collected" verified by Apple, plus Face ID and a stealth mode.

Trade-offs: Nine ratings — the 5.0 means nothing yet. Pricing appears at both $39.99 (founder’s annual) and $59.99 on the App Store, so check which you are being offered.

synqology — a health app that added peptides

M1 Labs · 4.9 stars, 8 ratings

Real strength in Apple Watch data — its AI chat reads live Watch metrics, and there is a color-coded body diagram for rotation.

The caveat: this is an Apple Watch health-intelligence app that added peptide tracking in April 2026, not a peptide-first app. None of its visible reviews mention peptide tracking. It has not been updated since April.

The Pep Planner — for sourcing, not just dosing

Belix Company LLC · 3.8 stars, 8 ratings on Google Play

The only product framed around research rather than personal health: orders, vendors, stockpile, delivery timelines and spending. Plus a buddy system for co-tracking one partner. Free tier includes the full reconstitution calculator, one protocol, ten stockpile items and three AI chats a day. $99.99 lifetime.

Trade-offs: We could only verify Google Play, despite iOS being claimed. Pricing differs between the web and Play listings.

PeptidePal — cheapest, but stale

SIGNALWORKS LABS INC · 3.4 stars, 5 ratings

$2.99/month or $29.99/year is the lowest price here, covering reconstitution, inventory, site tracking, journaling and CSV export.

Trade-offs: Not updated since February 2026 — the stalest app in this comparison. iPhone only. 3.4 stars on iOS and 1.5 on Google Play. Hard to recommend right now.

SHOTLOG — the only one with ads

RoboCFI LLC · 2.8 stars, 10 ratings on iOS, 2.4 on Google Play

Free with ads and a $0.99 removal purchase. Automatic site rotation, vial inventory, nutrition logging, provider reports. Shipping since December 2024.

Trade-offs: The lowest-rated product here on both stores. No reconstitution calculator, no Apple Health, and no website at all. Listed for completeness.

Dosefi — aesthetics first

Pink Pixel LLC · No ratings yet

Listed as "Dosefi: Skincare Routine Log" and built primarily around aesthetic treatments — fillers, microneedling, boosters — with peptides, GLP-1 and TRT as supported protocol types. Apple Health and Health Connect, calendar-synced reminders, treatment site map. $3.99/month.

Too new for ratings. Worth watching if you track aesthetics alongside peptides.

Peptide Pro App — for clinicians

PeptidePro LLC · Web only

The only product here with a clinician tier for managing multiple patients’ protocols. Dosage, order and blend calculators, a 100+ peptide encyclopedia, a cycle and rest-period calendar, dose titration, CSV and PDF export.

Trade-offs: No native apps. No free tier.

My Pep Calc — web, and newest

Web · Free tier plus paid plans

A browser-based tracker, installable as a PWA. Free tier covers three compounds with the reconstitution calculator, dose log, site rotation and half-life charts. Plus at $9/month, Pro at $19/month, and a $149 lifetime founder deal, with a 7-day trial on paid plans.

Trade-offs: No native app and no store ratings, so there is no independent signal on reliability yet. $19/month for Pro is the highest ongoing price in this comparison. Note that their roundup article and their pricing page currently disagree with each other on both the free-tier limit and the Pro price — go by the pricing page.

Peptide tracker vs. spreadsheet vs. notes app

Plenty of people track in a spreadsheet, and for one compound at a steady dose that is fine.

It stops being fine at three points:

When you reconstitute. A spreadsheet will happily carry a units error through an entire vial. A purpose-built calculator will not.

When you run more than two compounds. Overlapping schedules, different frequencies, separate vials with separate expirations. Manual tracking degrades quietly here, and the failure mode is not noticing you missed a third of your doses.

When you want to know whether it worked. Correlating dose history against sleep, weight, mood or bloodwork is exactly the thing a spreadsheet can do and nobody actually does.

A notes app fails earlier, because it does no math and sends no reminders.

How to choose

Start free. Peptide Tracker (Log & Reminder) costs nothing and covers the fundamentals well. Regimen’s free tier gives you every feature on one compound, forever. There is no reason to pay before you know what you need.

Then find your actual constraint — not the longest feature list, the one thing you will hit a wall on:

• On Android? That eliminates about half this list immediately.
• Handing data to a doctor? Sort by export: Protocol and PepTracker do CSV and PDF.
• Reconstituting powder? You need a real reconstitution calculator, which rules out Shotsy and SHOTLOG.
• Privacy-sensitive? Peptide Tracker & Calculator and Protocol carry clean "no data collected" labels. Several apps here, ours included, do not.
• Hate subscriptions? Smart Peptide Tracker at $34.99, or The Pep Planner at $99.99, once.

Weight the review count, not the star average. A 4.7 across 500 reviews is a far stronger signal than a 5.0 across 9. Ten apps here, ours among them, have fewer than 25 ratings.

Check the last update date. Two apps here have not shipped in over four months.
