Peptide Tracker Apps
Is There a Free Peptide Tracker App? What "Free" Actually Gets You
You can track peptides for free — but "free" means very different things depending on the tool. Here is what each free option actually gives you, and where the limits show up.
Search "free peptide tracker app" and you'll get a mix of spreadsheets shared on forums, generic medication reminders, and apps that say "free" but wall the useful parts behind a paywall. "Free" is doing a lot of work in those results. This guide breaks down what each free option actually gives you, where the limits show up, and how to track a peptide protocol for free without ending up with a pile of manual busywork.
The three kinds of "free"
When something is described as a free peptide tracker, it almost always falls into one of three buckets — and they are not equal.
1. Free-form tools (notes apps and spreadsheets)
These are genuinely free and infinitely flexible. The catch is that you are the software: you build the columns, write the reconstitution formulas, remember to rotate sites, and manually check expiration dates. For a single compound it works. Add a second peptide, a reconstituted vial, and a titration schedule, and the upkeep quickly outweighs the zero price tag.
2. Free app tiers
A dedicated app that is free to download gives you the peptide-specific machinery — dose logging, reconstitution math, injection-site rotation, inventory — without building it yourself. Some features may sit behind a subscription, but the core loop is usable for free, and there is no setup tax.
3. Free tools (calculators)
A free calculator does one job well: it converts a vial amount, BAC water volume, and target dose into the exact draw. It won't log or trend anything, but it removes the most error-prone step for free. LynkDose's reconstitution calculator runs in the browser with no signup.

How to track peptides for free with LynkDose
LynkDose is free to download on iPhone. You get the free reconstitution calculator, and a 7-day free trial of the full feature set so you can log doses, rotate injection sites, manage vial inventory, and chart 30-day trends against Apple Health before deciding whether an optional subscription is worth it. There is no better way to find out if a tracker fits your routine than actually running your protocol through it for a week.
It's also local-first: your logs stay on your device, only anonymized, condensed summaries ever leave it to power optional AI features, and your data is never sold or used to train AI models. "Free" should never mean "you're the product" — especially with health data this personal.
Track your protocol free for 7 days
Download LynkDose free, use the built-in calculator, and log a full week of your protocol before you decide anything.
Download on the App StoreThe honest bottom line
You can absolutely track peptides for free — start with the free calculator and a free app download. Free-form spreadsheets cost nothing but make you do the work; a purpose-built free app tier does the peptide-specific parts for you. Pick based on how much manual upkeep you want to own, then upgrade only once you know you'll keep tracking.
Frequently asked questions
Is there a free peptide tracker app?
Yes. LynkDose is free to download on iPhone and includes a free web-based reconstitution calculator plus a 7-day free trial of the full feature set. Spreadsheets and notes apps are also free, but they lack reconstitution math, injection-site rotation, inventory reminders, and trend charts. A dedicated app free tier gives you far more of the workflow without manual setup.
Can I track peptides for free without downloading an app?
Partly. The free peptide reconstitution calculator runs in your browser with no signup, so you can work out an exact draw volume in millilitres and insulin-syringe units for free. For ongoing logging — doses, sites, inventory, and trends — you will want a dedicated tracker rather than re-doing the math each time.
What is the best free way to track a peptide cycle?
The best free approach is a purpose-built peptide tracker rather than a blank spreadsheet, because the app already knows about reconstitution, insulin-syringe units, injection sites, and expiration dates. Start with the free calculator and a free app download, and only consider a subscription once you know you will keep using it.
Are free peptide tracking spreadsheets any good?
A free spreadsheet is a reasonable starting point for a single compound, and it costs nothing. It breaks down once you are reconstituting vials, rotating injection sites, running a stack, and trying to see whether your weight or sleep actually changed — none of which a blank spreadsheet does for you. That is the gap a dedicated tracker fills.
Your peptide tracker, done right
LynkDose logs every dose, manages your vial inventory, rotates injection sites, and charts your results against HealthKit data — all private and on-device.
