The Peptide App is a peptide tracking app available on iOS, macOS, priced as free (all unlocked) + membership. Outcome-first: pick a goal → get stacks; body scans, vetted vendors. It holds 4.51/5 on the App Store across 49 ratings. On paper it ships 5 of the 10 standard tracking features and 0 of the 5 genuinely-advanced ones we look for. Like most of the field, it leans on the same core set of features everyone else has.
The Peptide App is the peptide outcomes app, built to help you find the right protocol for your goals, run it confidently, and track the metrics that prove it's working. Every feature is unlocked from day one. Most peptide tools stop at "remind me to dose."…— The Peptide App's own store listing
