What it does

Built for people running
more than one thing.

Live levels, not a checklist

Most trackers store what you typed. This one runs every dose through the compound's half-life, so the chart shows an estimate of what may still be active in your system — not the last thing you logged.

  • One-swipe dose logging
  • Titration phases and on/off cycles
  • Reminders for every cadence
Live levels, not a checklist

Your bloodwork, on the same axis as your protocol

Log a panel by hand for free, or let Pro read it straight out of your portal's PDF. Then put a dose, a body metric and a lab marker on one chart and see whether they actually move together.

  • Reference ranges and plain-language explanations
  • Retest reminders
  • Biological Age from your own panel
Your bloodwork, on the same axis as your protocol

A goal with a date on it, not a hope

Set a target weight or body-fat percentage and the app projects when you will reach it from your own recent trend — not a generic curve, and measured from the day your protocol started. The band updates as the trend does, so a stall shows up as the date moving, which is the earliest honest signal that something needs changing.

  • Time-to-goal projected from your own rate
  • Weight, body fat and waist against the same timeline
  • What reaching it will cost from here
A goal with a date on it, not a hope

Every vial, counted down to the day it runs dry

Lots, suppliers, cost per vial and reconstituted expiry. The reconstitution calculator draws the syringe filled to the exact unit to pull, so you are not doing concentration arithmetic at the counter.

  • Doses left, not just millilitres
  • Low-stock and reorder warnings
  • Certificates of analysis kept with the vial
Every vial, counted down to the day it runs dry

Every vial, and what it costs you

Put the price on a vial once and it follows every dose you log — per dose, per week, per month, and what is still sitting in the fridge. Then every vendor you have bought that compound from is ranked by cost per mg of actual compound, cheapest first, so a bigger vial at a bigger price cannot flatter a worse deal.

  • Cost per dose, month and compound
  • Your sources ranked by cost per mg
  • Remaining inventory valued by fill level
Every vial, and what it costs you

Where it goes further

Most trackers log.
This one gives you evidence.

Half-life curves, injection maps and reconstitution maths are table stakes now — this app has all of them, free. The difference is what happens after you have been logging for three months and want to know whether any of it worked.

And a warning that counts what is inside a blend

Blends are stored as structured components, so if the same compound reaches you from two protocols on the same day, Today adds them together.

Arithmetic on the numbers you entered — not medical advice. It never blocks logging, and it is free on every plan.

The evidence, drawn

Four charts a checklist
will never give you.

Every one of these is generated from what you logged — no manual charting, no spreadsheet, no export step.

The handover

A document your prescriber
will actually read.

Thirteen pages generated from ninety days of logging, in one tap. It opens with the answer — every headline metric as start → current, with dates and change — then the charts and the full detail behind it.

Four pages of a generated BioHack Track protocol report: the At a Glance summary with weight, body fat, waist, muscle mass, blood pressure and sleep; active protocols; key insights; and behind it the estimated-active-levels, weight-trend and symptom-severity charts
A real report, generated from the demo protocol — not a mock-up. Pages 1, 2, 3 and 6 of 13.
At a GlanceEvery headline metric as start → current, with the date of each reading.
Estimated active levelsThe pharmacokinetic curve for each compound over the period.
Labs, flaggedEvery marker with its reference range, and anything out of range called out — 400+ recognised by name, no cap on how many you track.
Weight, BP & body compositionTrends over the same window, on the same dates.
Symptoms by weekAverage and peak severity, so a pattern is visible rather than recalled.
Full dose historyEvery logged dose with date, time, compound and amount.

The other report

What it costs, and
what it costs to finish.

The same one-tap export, pointed at your money. Monthly spend, spend by compound, a cumulative curve, every vendor ranked by cost per mg — and the number nobody else works out: what reaching your goal will cost from here.

Four pages of a generated BioHack Track financial report: summary with total spend and average cost per dose, a monthly spend bar chart, the cumulative spend curve, cost-to-goal analysis, and a per-compound cost-per-mg table
Generated from the same demo protocol. Pages 1, 2, 3 and 4 of 6.

Works with

Peptides, GLP-1s,
TRT and HRT.

Over 200 compounds with half-life, dose ranges and mechanism — including the GLP-1s people are actually prescribed, from semaglutide to tirzepatide. There are guides for tracking a semaglutide ladder, reading tirzepatide progress past the scale and keeping a vial inventory that counts itself down.

Also on the timeline

Your cycle, on the same
axis as your protocol.

Weight, appetite, sleep and side effects move on a hormonal schedule of their own. If you are not tracking that, a rough fortnight looks like the compound — when it may just be the luteal phase. BioHack Track puts the two on one timeline so you can tell them apart.

Predictions built from your cycles, not a textbook

Most apps assume a 28-day cycle and a 14-day luteal phase. This one learns your own luteal length from the ovulations you have actually measured, and projects from that — so the estimate gets better the longer you log.

  • Current phase and cycle day at a glance on Today
  • Log an ovulation you measured — it always beats the estimate, and every screen tells you which one you are looking at
  • Basal body temperature plotted straight onto the phase band
  • Phase as an overlay on your correlation charts, beside weight, labs and doses
  • Period and symptom logging, with full cycle history
Cycle tracking on the Today tab — current phase, the four-phase bar with today marked, estimated ovulation and predicted next period

Questions

Straight answers.

What is the best free peptide tracker app?

The honest answer is that it depends on whether you want a log or an answer. BioHack Track is free with no cap on compounds, protocols or history — most free tiers in this category stop at one or two compounds, a limited number of logs, or thirty days of history. Beyond logging, it is the only tracker that reads a lab panel straight out of your portal's PDF and turns your protocol into a report a prescriber will read.

Is BioHack Track really free?

Yes, and not as a trial. Unlimited compounds, protocols and vials, no history limit, no ads and no account. Dose logging, half-life levels, titration phases and cycles, reminders, inventory, the reconstitution calculator, the 200+ compound library, injection-site rotation and manual bloodwork entry are free permanently. Pro is optional.

Is there a plan for clinicians?

Yes. Provider is $19.99 a month or $199.99 a year and adds a patient roster with no cap on how many people are on it. A patient exports a record from their own app and sends it to you; you import it, read every lab, metric and dose as a chart, see what changed since their last record, write private notes and notes meant for them, record visits, propose starting, changing, pausing or stopping a protocol, send lab results and visit notes back into their record, and export a printable patient file for the chart. Patient records are stored only on your device, in a separate database that is never synced to iCloud. Provider includes everything in Pro. BioHack Track is a record-keeping tool: it does not prescribe, and a change sent through it is not a prescription.

What does BioHack Track Pro include?

The part that answers whether it worked: importing a lab panel from your portal's PDF, reading a smart-scale photo, body composition trends, before-and-after photos, dose-versus-lab correlations, Biological Age, a doctor-ready PDF, cost reports, certificates of analysis and household profiles. $2.99 a month or $32.99 a year. No trial — the free tier is the trial, and it does not expire.

Can I track GLP-1s like Zepbound, Mounjaro, Wegovy or Ozempic?

Yes. Semaglutide, tirzepatide and retatrutide are in the library with half-life data, and the app handles the weekly cadence, titration schedules and pen or vial inventory that go with them. It also tracks TRT, HRT, peptides, supplements and anything you add yourself.

Which peptides does it cover?

Over 200 compounds with half-life, common dose ranges, mechanism and cautions — BPC-157, TB-500, ipamorelin, CJC-1295, GHK-Cu, tesamorelin, MOTS-c, KPV, semax, selank and the rest — plus 21 pre-made blends with per-component milligrams so you can dose by a single ingredient. Anything missing you can add yourself.

Does it calculate reconstitution?

Yes, and it draws the syringe. Enter your vial size and the bacteriostatic water you added, and it shows the concentration and the exact unit to draw to on a U-100 barrel. Your vial then counts itself down as you log, in doses rather than millilitres.

What happens to my data if I stop paying?

Nothing is deleted. Every dose, lab result, photo, scan and profile stays exactly where it is; the Pro features lock and the data does not. It all returns the moment you resubscribe, with no restore step. Backup, restore and CSV export are free on every plan and always will be.

Is my health data private?

There is no account and no password, so there is nothing to sign in to and nothing to breach. Your protocol lives on your device and syncs through your own private iCloud, moving between your iPhone and iPad without passing through a server we operate. Nothing is sold, shared or used to train anything.

Can I move my history over from another tracker?

Yes, and it is free. Importing your existing history costs nothing, because charging someone to move in is charging them at the exact moment they are deciding whether to bother.

How much bacteriostatic water should I add to a peptide vial?

That is your decision, but the arithmetic is not. Whatever volume you choose, the calculator on this page turns your vial size and water volume into a concentration and the exact number of units to draw on a U-100 syringe. More water means a larger, easier-to-measure draw for the same dose; less water means a smaller one. The app never recommends an amount to take.

How do I know how many units to draw on an insulin syringe?

Units are just hundredths of a millilitre on a U-100 syringe. Divide your dose by the vial's concentration to get the volume, then multiply by 100. The calculator above does it for you, and the app draws the syringe filled to that mark so you can check it against the barrel in your hand.

What is half-life, and why does it matter for peptides?

Half-life is how long it takes for half of a compound to clear. It matters because it decides how much is estimated to still be active when your next dose lands — BPC-157 halves in about five hours, TB-500 in about two and a half days, semaglutide in about a week. The app models every logged dose against its half-life, which is why the levels chart shows a curve rather than a list.

Can I track injection sites and rotate them?

Yes. Every dose records a site, the next site in your rotation is shown before you log so you know where to go, and a body map lets you override it. Rotation advances automatically as you log.

Can I track TRT and HRT, not just peptides?

Yes. Testosterone cypionate, enanthate, HCG and the rest are in the library, and the app handles intramuscular and subcutaneous routes, oil-based volumes, weekly and twice-weekly cadences, and bloodwork alongside them.

Can I track a blend or a multi-peptide vial?

Yes. Blends carry per-component milligrams, so you can dose by the blend total or by one ingredient and the app converts between them. It also warns you if a compound reaches you from two protocols at once — including the portion hidden inside a blend.

Does it work on Android?

Yes. BioHack Track is on iPhone, iPad and Android. The iPhone version syncs through your private iCloud; the Android version syncs through your own Google account, and both work fully offline.

Can I track a partner or family member in the same app?

Yes, with Pro. A household profile keeps a second person's protocols, inventory, doses and labs completely separate from yours, with its own reminders — no second account and no second phone.

How do I export my peptide log?

Settings has a full CSV export and a complete backup file, both free on every plan. Your dose history, labs, check-ins and inventory come out in a format you can open in Excel or Numbers, or re-import later.

Does it track menstrual cycles alongside a protocol?

Yes, with Pro, and it is deliberately separate from protocol cycling. Turning it on adds a Cycle card to Today with period logging, phase and next-period projections, and a cycle overlay on your wellness charts — so you can see how a compound lands against where you are in your cycle rather than treating every week as identical. Projections are estimates for tracking only, not for contraception or medical decisions.

What is the difference between cycles and cycle tracking?

Two different things that share a word. An on/off cycle is part of a protocol — weeks on, weeks off, with reminders that follow it — and that is free. Cycle tracking means menstrual cycle logging with phase overlays, and that is a Pro feature.

Is BioHack Track a medical device or medical advice?

No. It is a personal tracking and organisation tool. It does not diagnose, prescribe, or recommend doses, and the compound library is general-knowledge reference you can edit. Decisions about what to take belong with you and a qualified prescriber.
