Peptide Plug vs Peptide Tracker

Peptide Tracker (peptidetracker.ai) is a free native iOS and Android app with protocol scheduling, detailed vial inventory, injection-site groups, estimated plasma curves, education and community features. Here is where it differs from Peptide Plug’s forecasting-focused web app.

Short version

Choose Peptide Tracker if a completely free native app, detailed supply handling, injection-site groups or its community matters most. Choose Peptide Plug if you want desktop access, cost and run-out forecasting, labs, private progress photos, validated CSV import and downloadable summaries.

Does Peptide Tracker have cost forecasting?
Not currently. Peptide Tracker's published feature set covers dose logging, adherence scoring, inventory, plasma-level estimates and a compound library, but not live cost-per-dose or cycle-cost forecasting.
Which one has a mobile app?
Peptide Tracker has native iOS and Android apps plus a free web calculator. Peptide Plug is a web app that works in modern phone, tablet and desktop browsers and can be installed to your home screen, but does not have a native app store listing.
