The full stack

One app for the whole protocol

Peptides, nutrition, labs, recovery and body composition — tracked together, so the patterns actually show up.

Private by design

Your data stays yours

Pep Journey is local-first. Your records live on your device, and the sensitive ones are encrypted at rest. Optional features send only what they need — nothing more.

  • On-device & encrypted. Health records are stored locally and encrypted at rest with a key only your device holds.
  • Apple Health stays put. Read-only, and never sent to the AI. It stays on your phone.
  • No ads, no tracking. No advertising SDKs, no third-party analytics, no selling your data.
  • You're in control. Export everything, or wipe it all, whenever you want.
