“Why did this drop?”
Health, further.
The health data you already have, scattered across wearables, labs, records, and your genes, read together as one private, personalized second opinion.

“Does this affect my Rx?”
Is my HRV crashing because my ferritin dropped?
The data exists. The answer doesn't, and you're the one left to connect it.
Why this matters
Your health is a puzzle, and you’re holding half the pieces. With half, you guess. Read together, the picture is obvious.
Why Further HealthHow it works
Every health marker, unified into one private profile.
Further Health brings in each major kind of consumer health data and reads them together. Most apps cover one slice. Further covers the whole picture and runs the analysis mainly on your own devices.
The core loop
- Connect
- Understand
- Act
- Track
- Improve
A second-opinion engine, not another dashboard.
Ranked hypotheses with confidence levels, supporting evidence drawn from your own data, and clear next steps. Observations to discuss with your clinician, not a diagnosis.
Further Genomics
The deepest layer: your DNA, read on your own Mac, with the positions your chip missed filled in.

Privacy & security
Privacy is architectural, not aspirational.
01 · Storage
Two-tier encrypted vault, on your own devices.
Tier 1 holds your full health record, encrypted column-by-column with AES-256-GCM under a KEK/DEK split derived from your passphrase. Tier 2 is a one-way pseudonymized copy, and the only data premium AI features can see.
- Cipher
- AES-256-GCM
- KDF
- Argon2id
- Password rotate
- re-wrap DEK in ms
02 · Egress
Deterministic privacy filter on every outbound call.
A regex-based firewall, hardened by clinical BERT and RoBERTa NER models as advisory cross-checks. ML never makes the privacy decision. The gate is deterministic. Any layer detecting PHI hard-blocks.

03 · DNA privacy
Your DNA is your fingerprint and stays on your device.
Genomes can never be revoked or changed. Further parses your raw file locally and reads only the SNPs needed for analysis. Your raw data is never uploaded, never logged, never shared. Same SNP, same finding, every time.
- Parsing
- local-only · raw file never leaves device
- SNPs
- 711 read · 81 active risks
- Pharmacogenomics
- 229+ drugs across 19 enzymes

How it compares
Most health apps cover one or two slices. Further reads them together.
