Best Peptide Tracker Apps 2026: Free & Paid Apps Compared

Regimen, the most complete peptide tracker: it puts your doses, labs, symptoms and health data on one timeline and runs pattern detection across all of it. It is free for one compound and handles stacks on Premium. PepTracker is the simpler iOS-only alternative, and Smart Peptide Tracker is the one-time-price option.

Regimen. Free for one compound, no time limit; Premium if you track more than one. The free tier is most of the app: lab tracking, the four calculators, side effects and 50+ daily markers, injection site rotation, half-life tracking and pattern detection. Peptide Tracker is free with no paid tier. PepTracker has a free tier with a protocol limit, and Smart Peptide Tracker has a free core with a paid Premium. PeptIQ and PeptidePal need a subscription.

Regimen. It is a free peptide tracker app for iPhone and iPad for your first compound, and it works with Apple Watch: dose reminders come through to your wrist, and you can snooze one or mark a dose as taken from the Watch. If you want a lighter iPhone log, PepTracker is an alternative.

Regimen, PeptIQ, Peptide Tracker, PeptidePal, Smart Peptide Tracker and Shotsy all ship on Android. Regimen is free for your first compound on Android, runs on the web too, and syncs weight, sleep and other health data from Health Connect. PepTracker is iOS only.

Regimen has four reconstitution calculators in the app: standard, reverse (pick your dose and syringe, get the water to add), oil-based and nasal spray. If you only need the numbers, Regimen’s peptide calculator is also free on the web, with nothing to install.

Yes. Any spreadsheet works for one peptide: one row per dose, with the date, the compound, the dose in mg, the units drawn, the injection site and the date you mixed the vial. What a sheet can’t do is remind you, do the syringe math, or flag a vial past its beyond-use date. That is where an app like Regimen, free for your first compound, saves the work.

Log four things every time you dose: the compound, the amount, the injection site, and the date. A notes app or spreadsheet works fine for one peptide. Once you add a second compound on a different schedule, start cycling, or mix more than one vial, a peptide tracking app does the remembering for you, with reminders, site rotation, and the reconstitution math in one place.

Yes. A peptide calendar app shows which compound is due on which day, which matters once you run more than one on different schedules: something daily, something twice a week, something five days on and two off. Regimen shows the week ahead with each dose on its day, marks what you have already taken, and reminds you at the time you set.

Regimen. It suggests the next site on a body map, lets you add your own spots, keeps a separate rotation for each compound, and lets you rest a sore spot until it heals.

Regimen tracks start and end dates across multiple compounds on one timeline with a half-life visualizer, so on-cycle and off-cycle periods are visible per compound.

Regimen tracks vial creation dates with beyond-use-date warnings and inventory across your protocol. For general storage guidelines, the peptide storage guide covers everything.

Yes: Regimen, PeptIQ, and Smart Peptide Tracker as a paid add-on. Regimen scans your lab report and plots each marker on your dose timeline, with pattern detection on top, covering panels like testosterone, IGF-1, fasting glucose, lipid panels, and custom markers.

A calculator handles the math: how many units to draw for a given dose, how much BAC water to add to a vial, what concentration a reconstituted vial has. A tracker logs doses over time, schedules reminders, and records how you feel. Regimen does both. PeptIQ scans a vial label to fill in the reconstitution and inventory fields for you. PepTracker has a forward-only calculator (no reverse mode).

Yes, if the app supports multiple compound categories. Regimen handles GLP-1 compounds and peptides in the same protocol view. Shotsy is GLP-1 only and does not support peptide compounds.

If you want unfiltered takes, r/Biohackers has a long thread asking what people want from a peptide tracker app. Threads like that are where you learn how an app feels after month three. Several Reddit users who tried other apps say they settled on Regimen; their comments are quoted on this page.

Look at how long it has shipped updates, whether the developer is identifiable, and whether the calculator shows its math instead of hiding it. Review counts help, but they reward age more than quality, so treat them as one signal rather than the answer.

Apps like Medisafe work for basic reminders, but they don’t understand peptide-specific concepts. They can’t calculate reconstitution concentrations, they don’t know about cycling schedules, and they treat every medication the same way. Peptide protocols have unique requirements (supply tracking, syringe unit calculations, site rotation, half-life tracking) that general apps don’t address.

No, and they shouldn’t. These are tracking and calculation tools, not medical advice platforms. They help you manage your schedule, log what you’re taking, and do the reconstitution math correctly. Dosing decisions should come from your own research, your provider, or established community protocols. If an app has an AI chat, verify anything it tells you.

Search “peptide tracker” in the App Store and you get more than twenty results. Most have a handful of ratings, no site, and nothing published you could check a claim against. We review the ones with a real user base and enough detail on their own listings to verify, re-checked every month (last on October 26, 2026). General medication trackers, fitness apps with supplement logging, and anything not updated in over two years are out. Two newer ones are not on the list yet: MyPeptideApp, which runs in a browser only, and PeptideKit, on iPhone.
