Adding lab results

On the Health tab, open Lab Results. You can:

• Add manually — enter a marker, value, unit, and reference range (there's a toggle for qualitative results like “Negative” or “Trace”).
• Import from a lab portal — bring in a PDF, a CSV, or a .zip of your whole history. The importer reads full panels, including censored values (like <15), one-sided ranges, and CBC-style units.

Results are grouped by draw date, and you can tap View All Lab Trends to chart any marker over time.

Importing a whole lab history at once

Most portals have a Download All button that hands you a .zip of every report. Import that file directly — BioHack Track opens the archive and reads every PDF and CSV inside in one pass. You don't need to unzip it or import reports one at a time.

Re-importing is safe. Every result is checked against what you already have, matched on marker, draw date, and value. Import the same file twice and nothing doubles; import next month's download and only the new draws are added. You'll see exactly what happened — for example *“Imported 64 new results (56 already in your history, skipped).”*

That also covers the messy real case where an archive contains the same panel twice (say a CSV and a PDF of one draw) — it's counted once.

Different labs, one chart. Providers spell markers differently — “T3 Free” vs “Free T3”, “HDL-Cholesterol” vs “HDL Cholesterol”. These are recognised as the same test, so switching labs doesn't split your history into two trend lines. Genuinely different measurements stay separate, so an absolute count is never mixed with a percentage, and an inflammation-adjusted ferritin is never merged with a raw one.

Fixing or removing lab results

Imports aren't permanent. On the Health tab, open a draw date under Lab Results and:

• Tap any marker to correct its value, unit, date, reference range or notes — useful when a PDF was read slightly wrong.
• Swipe a marker to delete just that one.
• Swipe the draw date to delete every result from that day at once — the quickest way to undo an import that brought in the wrong thing.

You can also delete a single result from inside its editor. Trends, lab markers and your biological age all recalculate immediately.

Understanding a result — ranges & what high/low mean

Tap What does this mean? under any marker's chart for a plain-language explanation of what it measures and what a high or low reading commonly indicates. Over 400 markers are covered, from a standard CMP to specialty panels — organic acids, heavy metals, mycotoxins, allergy IgE, and autoimmune antibodies.

Where it helps, you'll also see two ranges:

• Your lab's range — taken from your own report. This is the one that counts.
• Typical adult range — a general reference, shown for orientation when your report doesn't include one.

Ranges legitimately differ between labs and by age and sex, so when the two disagree, go by your own report. Everything here is educational — not medical advice.

Biological Age (PhenoAge)

Once you've logged a lab draw with the needed markers and set your date of birth (Settings → Date of Birth), the Health tab shows your Biological Age — an estimate of how old your body reads based on your bloodwork, using the published Levine PhenoAge method. A chip tells you whether you're testing younger or older than your calendar age, and the detail view shows what's helping and hurting the number over time. It's derived from your labs on the fly — nothing extra to enter.

Weight, fitness & correlations

The Health tab charts your weight and fitness trends and offers a Correlations card that lines up a metric (like weight or mood) against your dosing so you can eyeball what's moving together. Add data via Daily Check-In or Apple Health.

Every chart in the app uses the same control to choose what it plots: tap the metric dropdown at the top of the chart and pick from the list (longer lists are grouped into sections). Whether you're on the Health & Fitness chart, Body Metrics, Wellness vs. Protocol, or a symptom correlation, the picker works the same way.

Apple Health sync

BioHack Track can pull weight, steps, active energy, calories, sleep, lean body mass, and the full heart family — resting heart rate, walking heart rate, heart rate variability (HRV), and VO₂ max — from Apple Health, and write your logged doses back as medication records. You're asked for permission on first launch; you can adjust it anytime in the iOS Health app → Sharing → Apps. Sleep and the heart metrics are read-only by design. The heart metrics show up as comparison lines on the Progress tab's Wellness vs. Protocol chart.

Body composition from a smart scale

Beyond weight and body fat %, BioHack Track tracks a full body-composition panel: muscle mass, fat-free mass, bone mass, body water %, visceral fat, subcutaneous fat, BMR, and metabolic age. Three ways to get it in:

• Type it — Daily Check-In has a Body Composition section for every field.
• Apple Health — lean body mass syncs automatically if your scale writes to Health.
• Import a CSV — export the readings from your smart-scale app (Withings, Renpho, Eufy, etc.) and use Settings → Import from Another App. The importer matches columns by name, so most scale exports just work.

Everything you add flows into the comparison charts and both the Doctor and Financial reports.

Menstrual cycle tracking

BioHack Track includes an opt-in period tracker — turn it on in Settings → Cycle Tracking. Once enabled, a Cycle card appears on Today:

• Log Period records a period's start (and optional end) and flow. Logging your period starts is what powers the projections — the more you log, the more accurate they get.
• Log Symptoms tags cramps, headaches, mood, and anything else onto the current cycle.
• The card shows your current cycle day and phase, a phase bar (menstrual / follicular / ovulation / luteal), and a projection of your next period and estimated ovulation.

Tracked against your protocol: on the Progress tab's Wellness vs. Protocol chart, choose Cycle Phase from the metric menu to see your cycle phases as colored bands with period-start and protocol-start markers — and the phases also shade faintly behind your energy/mood/sleep lines so you can spot cycle-linked patterns. Your cycle history is also included in the Doctor Report.

Projections are estimates for tracking and conversation — not for contraception or medical decisions.
