Pep Journey — Today screen
A guided tour

Everything, one tap away

Six of the screens you'll live in. Swipe through the app the way it actually looks.

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.
