How to pick a
peptide tracker.

Most apps in this category log a dose and set a reminder. The difference shows up three months in, when you want to know whether any of it worked — and that is a question about levels, labs, body composition and cost, not about checkboxes.

The five things that actually differ

1. Does it model levels, or just store entries?

A checklist tells you what you typed. A tracker worth the name runs every dose through the compound's half-life so you can see estimated active levels — which is what makes a twice-weekly protocol legible at all. Ask whether the app knows each compound's half-life, or whether it is just a list with dates on it.

2. Does it count the vial down?

Doses come out of a physical vial that expires. An app that tracks doses but not inventory leaves you doing reconstitution arithmetic at the counter and guessing when to reorder. Look for doses remaining rather than millilitres, and for a reconstitution calculator that draws the syringe.

3. Can it take your bloodwork?

Typing a panel in by hand is the reason most people stop. Importing the PDF straight out of your lab portal is the difference between a tracker you keep using and one you abandon in month two. Ask how many markers it understands, too: BioHack Track recognises over 400 by name and charts any marker your lab reports, with no cap on markers or draws.

4. Does it produce something you can hand over?

Appointments go better with a document. A dose list is not that document — protocol, adherence, labs, trends and photos in one PDF is.

5. What does it cost you, and what does your data cost to leave with?

Two separate questions. Per-dose and per-month cost tracking is rare and genuinely useful. So is being able to export everything as CSV and take a full backup without paying — an app that charges for the exit is telling you something.

What each app says it does

Every cell reports what that app's makers say publicly — their App Store listing or their own website, read on the date above. A blank means neither mentions it: not a claim that the app cannot do it. BioHack Track is held to exactly the same standard, which is why it has blanks too. Read on .

A dot means that app’s listing does not mention the feature. It is not a claim that the app lacks it — only its makers can say that. Three of these apps require a subscription to track at all and do not publish the price on their listing; we have said so rather than guessed a number.

A word on free tiers

Watch for a free tier that caps the number of compounds or the length of your history. Those are the two things a tracker is for, and capping them makes the free tier a demo. BioHack Track leaves both unlimited on the free plan, along with reminders, the half-life chart, titration and cycling, the compound library, the reconstitution calculator and manual bloodwork entry.

A dash means that app’s listing does not mention the feature — not a claim that it cannot do it; only its makers can say that. It cuts against us too: we deliberately have no AI answering questions — Evidence Check retrieves and grades real papers instead, so there is nothing that can invent a citation. Three of the nine require a subscription before you can track anything, and none of those three publishes a price. The full detail, with every quote →

BioHack Track is free. Unlimited compounds, protocols, doses and history, no ads and no account — and the backup and CSV export are free too, so your data is never held hostage.

Questions

What is the best peptide tracking app?

It depends on whether you want a reminder or an answer. If you are running one compound on a fixed schedule, almost anything works. If you are running several, titrating, and want to connect the doses to your labs and body composition, you need half-life modelling, lab import and inventory — which is a much smaller field.

Is there a free peptide tracker?

Yes. BioHack Track is free for unlimited compounds, protocols, doses and history, with reminders, the estimated-levels chart, titration and cycling, the 200-plus compound library and the reconstitution calculator included. Backup, restore and CSV export are also free.

Do I need an account?

Not for BioHack Track — it works entirely offline and syncs through your own private iCloud if you want it on more than one device. Anything that forces an account before you can log a dose is collecting something.

Can one app handle peptides, GLP-1s and TRT together?

It should. They are all injectables on schedules with bloodwork attached, and splitting them across apps is what pushes people back to a spreadsheet. BioHack Track treats them the same way and puts them on one timeline.

What about tracking more than one person?

Rare, and usually absent. Household profiles keep a second person's schedules, doses, inventory and labs completely separate from yours rather than mixing them into one log.
