Comparison

Peptide Plug vs Peptide Tracker

Q: Is Peptide Tracker really free?

Yes — Peptide Tracker (peptidetracker.ai) states outright that it is 100% free with no subscription and no paywall. Peptide Plug also has a free tier (1 active cycle, calculator, one forecast, full research library, no card required), with a paid Pro tier for unlimited cycles and automated alerts.

Peptide Tracker (peptidetracker.ai) is free, has native iOS and Android apps, and carries a 4.9★ rating across 1,500+ App Store reviews — it's a strong, established option. Here's an honest, feature-by-feature look at where it's ahead of Peptide Plug, and where it isn't.

Short version

If you want free logging, reminders and a compound library on your phone, Peptide Tracker is a solid, proven choice. If you're running a real cost-per-dose protocol — blended vials, titration steps, and knowing what's left to spend before you run out — that's the gap Peptide Tracker's own published feature set doesn't cover, and it's what Peptide Plug is built around.
