Best peptide tracker apps, 2026 — compared

A feature-by-feature look at the trackers people actually search for, including ours. Every competitor cell below is sourced to a specific, dated finding; where we couldn't verify something, it says so instead of guessing.

We make VialMath. This comparison is biased by definition — we wrote it. Every competitor claim below is sourced, and where we couldn't verify it, we say so. Read the sourcing at the bottom of each section rather than take our word for the rows themselves.

Feature and pricing comparison

Pulled from a direct competitive teardown (app-store metadata via Apple/Google's own public APIs, plus each vendor's own pricing and marketing pages) and a separate pass reading each app's own public App Store reviews. Both research passes are dated 2026-08-26/27. "Not verified" means the research did not find a sourceable answer — not that the answer is no.

1 research/peptide-tracker-teardown-2026-08-25.md — direct iTunes/Google Play API pulls and each vendor's own site/pricing page, 2026-08-26. 2 research/low-star-review-mine-2026-08-27.md — quoted directly from each app's public App Store review feed (Apple's public RSS endpoint), 196 reviews rated ≤3★ read in full, 2026-08-27. 3 Absence noted across both research passes — neither a "decision log" / gate-check feature nor a public test suite was found described on any competitor's site, store listing, or review text searched. Absence of evidence, not confirmed absence — flagged as "No — not found" rather than a stronger claim. 4 This site and products/protocol-engine/app/app.js — the one-time license check and no-data-leaves-device claim are the exact scoped wording cleared by counsel (see Privacy). 5 research/low-star-review-mine-2026-08-27.md, section (c)(1): grepped app.js/index.html for "subscri", "account", "login" — zero hits; the app makes no network calls capable of gating a feature behind payment after purchase.

Where they honestly beat us

A comparison that only ever favors the author isn't trustworthy. These are real, sourced advantages the competitors above have — not softened, not buried.

If the wedge fits

One-time price. No subscription, ever.
