## What is RTK Health?

RTK Health is your private health diary and AI coach — one place to log your whole health story and actually understand it.

Track vitals, nutrition, sleep, workouts, mood, and symptoms in seconds. RTK Health's AI reads everything together and gives you a clear, personalized analysis that connects the dots most apps miss — then turns it into simple goals and coaching you can act on.

WHAT YOU CAN DO
• Log fast: vitals (heart rate, blood pressure, weight, temperature), meals (barcode scan + AI photo estimate), sleep, workouts, mood, and symptoms
• AI analysis: a personalized read of your trends, written for you — not generic tips
• Goals & streaks: turn insights into habits, with reminders and progress tracking
• Workout programs: import a coach's plan or draft a multi-week program from your goals, with per-set tracking
• Labs & documents: upload blood panels and clinical documents; the app extracts the values and tracks them over time
• Cycle, pregnancy & postpartum tools, veterans' health prep, and mental wellbeing check-ins

CONNECTS YOUR WEARABLES
Apple Health, Fitbit, Oura, Whoop, and Strava — RTK Health consolidates them into one record so your sleep, HRV, recovery, and activity all inform the same picture.

PRIVATE BY DESIGN
You are pseudonymous. We do not ask for your name, phone number, or address — your account is a cryptographic ID. Your health data is never sold in a form that identifies you and is never shared with advertisers. Sign in with Apple, Google, email, or a crypto wallet.

YOUR RECORD, FOREVER
Export everything any time. RTK Health is built to be the health record that outlives every app you have tried.

RTK Health is for wellness and personal tracking. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Always consult a qualified healthcare professional.


## Version history (last 5 releases)

### 1.4 — 2026-08-24

• Digital Twin — a new home for your measured body. Your heart, recovery, sleep, and aerobic fitness on one page, every number labeled measured or estimated, next to your 3D avatar and tape measurements. Then take it for a run on the simulation bench: ruck-march standards, race predictions with plain-language training plans, multi-day trip planning with food-and-water math, stair climbs, and a what-if slider that shows how losing or gaining weight would change every result. Free accounts get a fully interactive sample body — Premium runs it on yours.
• Fitness tests — log push-ups, plank, 2-mile run, deadlift, grip strength, jumps, shuttles, loaded carries and more, with how-to instructions on every test and context from published standards. A timed 2-mile or Cooper run measures your aerobic ceiling — no lab needed.
• Google Health connection — link your Google/Fitbit account for richer sync: per-workout heart-rate curves, max heart rate, and 1-minute heart-rate recovery.
• Garmin support — import activity files or a full Garmin export, including sleep.
• Coach upgrades — a redesigned messaging hub and richer client views, always under your sharing controls.
• Cycle tracking — tap any calendar day to log flow; predictions and fertility windows use it.
• Honest calorie targets — targets adapt only when your logging truly supports it, and a new "how you eat" setting (like two meals a day) keeps daily expectations fair.
• Plus: clearer lab-upload guidance (including a simple spreadsheet format), easier time entry, and a fix for a stuck zoomed-in screen.

### 1.3 — 2026-08-06

Coach messaging — a chat button on every screen for coaches and clients, with message notifications. Delete your account any time in Profile → Data & Privacy, and change your sign-in email without losing your data. Log HIIT and Tabata intervals, more supplement schedules, and a smarter coffee counter. Updated Terms and Privacy Policy.

### 1.2 — 2026-07-31

• Apple Health sync goes deeper: sleep, resting heart rate, heart rate variability, blood oxygen, VO2 max, and body composition now sync alongside workouts and steps — your tracker stays the source of truth and Apple Health fills in the gaps.
• Blood glucose tracking (for users who've added a diabetes diagnosis):   log readings or sync from Apple Health, see your time-in-range and trends, switch mg/dL ⇄ mmol/L, and keep a record of insulin doses — always your own record to discuss with your doctor, never dosing advice.
• Blood pressure & daily weight: users with hypertension see a 7-day home reading average; heart-failure users get a daily-weight card that makes day-to-day changes easy to spot.
• Migraine tracking: log attacks with severity, aura, and what helped — and see your monthly attack and medication-day counts at a glance.
• CPAP support: import your machine's data (OSCAR export) to see nightly usage, AHI, and leak trends alongside the rest of your health picture.
• Kidney health: users with CKD can see their lab trends — eGFR over time and key kidney values — pulled from lab reports they upload.
• New navigation on phones: a bottom tab bar puts Home, Log, Diary, Analysis, and More one thumb away.
• Women's health: import your Natural Cycles data, log basal temperature to the hundredth of a degree, and see spotting, LH surges, and pregnancy tests right on the cycle calendar — with your full multi-year history.
• Fitbit account exports can now backfill your history — days already covered by your live sync are skipped automatically.
• What fits you: your body measurements power a personal fit guide — body-shape read, size guidance, and tailoring notes.
• Faster everywhere: sign-in, dashboard loads, and marking a medication taken are all dramatically quicker, plus many fixes.

### 1.1 — 2026-07-12

• 3D Body Scan (Premium): record a short 360° video and get a personal
 3D avatar with body measurements you can track over time — with clear
 consent, automatic face blur, and delete-anytime controls.
• Deeper nutrition: meals now include fiber, sugar, sodium, saturated fat
 and more (shown as estimates), saved meals for one-tap logging, a 14-day
 fuel trend, and your eating window — inferred automatically, no timers.
• Supplements now count: link your supplement to its official label and its
 nutrients join your daily totals on days you mark it taken.
• Your coach can now see nutrition detail and (only if you share it) your
 body-scan progress — never your video.
• Cleaner dashboard: your daily focus and streak now take one line each, so
 your data is front and center.
• Sleep accuracy: interrupted nights now count fully — matching what your
 tracker’s own app shows.
• Many fixes and performance improvements.
