— Capabilities

Everything that moves the needle, nothing else.

§ 02 / FEATURES
01 — DASHBOARD
A composite readiness score, computed from your 28-day baseline.

Corpus Index blends HRV, sleep efficiency, training load, and nutrition into a single number — with the contributing factors broken out so you can see why.

02 — ORACLE
Advisor that has every signal in context.

Ask "why is my HRV up this week?" and get an answer that actually weighs your peptide cycle, sleep, and recent training.

YOU
Why HRV up this week?
ORACLE
+18% on baseline. Cut alcohol 12d ago — stronger effect than BPC.
03 — PEPTIDES
Cycle-aware, not just a reminder.

Stack timelines, dose schedules, vial inventory, and reminders that respect your protocol.

04 — FUEL
Snap a plate. Edit if you want.

Vision LLM gives a starting estimate. Barcode for packaged. You always confirm before save.

05 — TRUST
HealthKit is the source of truth.

No proprietary silo. Sign in with Apple. JWT to your VPS. Local-first; cloud is opt-in per signal.

— Process

Three steps. No setup tax.

Corpus reads what you already have. There's no migration, no manual logging marathon.

§ 03 / HOW IT WORKS
01
— Connect
Grant HealthKit access

Sign in with Apple, pick which signals to read. Whoop, Activa, Apple Watch all flow through HealthKit — no per-device integrations.

02
— Log
Snap meals, log peptides

Photo capture for fuel. A few taps for cycles. Corpus handles the data plumbing — you handle the eating.

03
— Ask
Talk to your data

The advisor answers with full context: 90 days of HealthKit, your meals, your peptide stack. No more guessing what's actually working.

— Surfaces

Four screens. Built for one user.

Every pixel earns its place. No tabs you'll never tap, no dashboards you'll never read.

§ 04 / SCREENS
— Pricing

Bring your own keys, or let us host.

Corpus is local-first. The cloud tier exists for longer context and historical aggregation — not because you need it on day one.

The Corpus Index alone is worth it. Wish I'd had this two stacks ago.

Finally a tracker that doesn't pretend peptides aren't a thing.

Local-first + opt-in cloud is the right call. I trust this more than any "wellness platform".
K. — beta
Privacy researcher

The vision estimates are off by 20% but that's fine — I edit and it learns my plates.
