Every "best peptide tracker" list on the internet is written by one of the trackers — including this one. So instead of a ranking, here are the criteria, the table, and the honest notes, with links so you can verify each claim in a minute. Prices checked August 2026.
The criteria
We compared six actively-developed trackers on the things users actually ask for in forums: does it work without an install, can it plan a multi-compound protocol (not just log shots), does it track vials and what each dose costs, does it model medication levels from half-lives, can it hold bloodwork, and does it cite sources for its reference content.
The comparison
| App | No-install web | Protocol builder | Inventory + cost/dose | Levels curves | Labs | Cited sources | Price/yr |
|---|---|---|---|---|---|---|---|
| Zyra Track (this site) | ✓ full web app — any device | ✓ multi-compound, phased | ✓ vials, BAC water, cost per dose | ✓ from published half-lives | ✓ | ✓ 681 papers, inline | Free during the founding period (no card) |
| Shotsy | — iOS | — single med | — | ✓ GLP-1 | — | — | $39.99–59.99 |
| PeptIQ | ✓ web app | partial | — | — | via partner | partial | $99 |
| Pep AI | — iOS | partial | partial (vault) | — | — | — | $39.99 |
| Regimen | — iOS | ✓ titration planning | — | ✓ hourly charting | — | partial | $39.99 (free: 1 compound) |
| MyPeptideApp | ✓ web | ✓ basic | ✓ basic | ✓ | ✓ basic | — | Free (donations) |
Where each app honestly wins
Shotsy is the most polished single-medication GLP-1 tracker on iOS — the app whose charts people screenshot into support groups. If you take one medication and live on an iPhone, it is a fair default. It does not cover research peptides or multi-compound protocols.
PeptIQ has the deepest library of research-peptide compound guides in the category and recently added a web app. Its reference content is where it shines; protocol and inventory tooling are thinner, and its history includes vendor partnerships — worth knowing when you weigh its recommendations.
Pep AI moves fast and its "compound vault" now tracks vials and reserves. It is iOS-first, its AI features are an add-on, and its reference content does not cite sources.
Regimen shipped the category's best titration planner — plan a dose change once and every future dose updates — plus hourly level charting. Its free tier (one compound) is real. It is iOS-only and covers less of the protocol-inventory-labs surface.
MyPeptideApp is free, built by one developer, and covers the core loop well in the browser. If price is the deciding factor, use it — genuinely. It does not have a research corpus, cost tracking, or labs depth, and one-person projects carry continuity risk.
Zyra Track — ours — is built for the whole protocol rather than the single shot: a phased protocol builder, inventory that knows what each vial cost and therefore what each dose costs, bloodwork storage, weight tracking, medication-level curves computed from published half-lives, and an Ask feature that answers from a cited research corpus (681 indexed papers, 79,000+ community reports) instead of from a model's imagination. It runs in any browser — phone, Android, desktop — with nothing to install. The honest trade-offs: pricing after the founding period isn't set yet (the app is free during the founding period, no card), and if you specifically want a native iOS home-screen experience, the iOS-first apps above feel more at home today.
How to choose in 30 seconds
One GLP-1 med, iPhone, want polish → Shotsy. Reading-heavy research-peptide user → PeptIQ. Free, forever, simple → MyPeptideApp. Planning titrations on iOS → Regimen. Whole protocol — multiple compounds, costs, labs, levels — in the browser → start Zyra Track free.
This comparison reflects prices and features as checked in August 2026; apps change fast, and corrections are welcome via support. No tracker here — ours included — gives dosing advice: they do arithmetic and record-keeping, and decisions belong with you and a clinician.
