Every feature, and exactly what it's for
VitaLog is organized into ten areas of functionality. Each one below lists what it does and a concrete, everyday use case — not marketing copy.
Offline-first architecture
The app is fully usable with no internet connection at all — scanning, extraction, charts, and search all run entirely on-device.
Skeuomorphic clinical design
Every screen is modelled on real clinical instruments — LCD diagnostic panels, manila folders, hospital pagers — so the interface feels immediately familiar.
Built for the Indian healthcare context
Indian generic medicine names, prescription shorthand (OD, BD, TDS), GS1 890-prefix barcodes, and India-specific banned-drug notifications are understood natively.
Health Vault & Records
Every lab report, prescription, and vital sign — captured once and organized automatically.
Offline-first document scanning
An on-device OCR and extraction pipeline reads blood work, biochemistry, lipid, thyroid, diabetes and vitamin panels, prescriptions, and discharge summaries, then structures every value automatically — no internet connection required.
Photograph a lab report the moment you receive it from your diagnostic centre and have every parameter, reference range, and flag entered for you before you leave the parking lot.
Multi-page document scanner
A guided capture flow with live edge detection, auto-crop, perspective correction, and image enhancement turns a stack of physical pages into one clean digital document.
Digitize a 6-page hospital discharge summary in one continuous session instead of scanning and re-uploading each page separately.
Unified health timeline
Reports, prescriptions, symptoms, vitals, appointments, workouts, and sleep are merged into a single chronological timeline you can search and filter.
Scroll back to exactly what happened in the two weeks before a flare-up, across every category of data at once, instead of checking five different screens.
Trend charts & personal baselines
Every recurring lab value is automatically charted over time, with your own historical range overlaid once enough data points exist — not just the generic population reference range.
See whether your haemoglobin is actually trending back to your personal normal after starting iron supplements, rather than only checking if it crossed a textbook cutoff.
AI-Powered Health Intelligence
A multi-provider AI router with automatic failover keeps an assistant available that actually knows your health history.
Multi-provider AI router
Chat, extraction, and analysis requests are routed across several hosted models with automatic retry and failover, so a single provider outage never takes the assistant offline.
Keep chatting with your health assistant uninterrupted even if one upstream AI provider is temporarily rate-limited or down.
Context-aware health chat
Every conversation is grounded in your real profile, recent lab values, medications, symptoms, and vitals — assembled fresh from your own encrypted data, never a static script.
Ask "why is my LDL flagged this time?" and get an answer that actually references your last three lipid panels, not a generic definition.
Doctor-visit preparation
Generates a print-ready summary and a shortlist of data-driven questions to ask your doctor, built from your recent abnormal results, active medications, and logged symptoms.
Walk into a 10-minute specialist appointment with a one-page brief instead of trying to recall three months of history from memory.
Symptom & trend correlation
Looks for statistically meaningful links between symptom entries, lab trends, and wearable data — like fatigue clustering around low B12 readings.
Discover that your recurring headaches line up with poor sleep nights, backed by your own logged data rather than a guess.
Medicine & Food Scanner
Point the camera at a barcode, package, or label and get an instant, sourced answer.
Barcode & label recognition
A layered recognition pipeline checks local caches, bundled Indian medicine datasets, open medical and nutrition databases, and AI identification in sequence — so a scan almost never comes back empty.
Scan an unfamiliar strip of tablets found in a family member's bag and quickly learn what it is before deciding whether to ask a pharmacist.
Drug interaction checking
Cross-references any newly scanned or entered medication against everything already saved in your profile and flags known interaction risks.
Get warned before adding a new over-the-counter painkiller that could interact with a blood thinner you're already taking.
Food & nutrition scoring
Reads nutrition labels and packaged food barcodes to surface a plain-language health score, flagged ingredients, and portion-aware macros.
Compare two packaged snacks on the supermarket shelf in seconds instead of decoding two nutrition panels by hand.
Banned & restricted drug alerts
Cross-checks scanned or extracted medicines against India's officially notified banned drug combinations and surfaces a clear warning.
Get flagged immediately if an old prescription contains a fixed-dose combination that was later banned by the regulator.
Security & Privacy by Design
Your data is encrypted on your device first — the cloud is an optional, user-controlled backup, never the source of truth.
On-device AES-256 encryption
The entire local database is encrypted at rest with a 256-bit key held in the platform's secure hardware-backed storage, not in plain application storage.
Lose your phone and know that whoever finds it still can't read a single lab value without your biometric or PIN.
Biometric lock & PIN protection
The app automatically locks after a short period in the background and requires Face ID, fingerprint, or a 6-digit PIN to resume.
Hand your phone to a friend to show them a photo without worrying they'll accidentally swipe into your medical history.
Panic wipe with safety backup
Five consecutive incorrect PIN attempts (or a configurable emergency tap gesture) trigger an automatic encrypted backup, followed by secure deletion of the local decryption key.
Protect your data under coercion or theft while still preserving a recoverable backup for yourself, not an irreversible total loss.
Zero-knowledge cloud backup
An optional passphrase-derived encryption layer can be applied before anything is uploaded to your own Google Drive — the passphrase itself is never stored anywhere, including on VitaLog's own infrastructure.
Back up to the cloud for peace of mind while keeping mathematical certainty that nobody but you can ever decrypt it.
Sync, Backup & Multi-Device
Backups live in your own Google account — never on a third-party server you don't control.
Your own Google Drive & Sheets
Structured backups are written directly to a private folder and spreadsheet workbook inside your personal Google account, with automatic retry and conflict resolution.
Switch to a new phone and restore your complete health history from a Drive folder you already own and control, no VitaLog account required.
QR device pairing
Generate a secure QR code on one device and scan it on another to stream a guided, real-time restore.
Set up your health record on a new tablet in a few minutes by scanning a code from your phone instead of re-entering everything manually.
Version history & rollback
The last several backup snapshots of every report are retained on Drive, so an accidental edit or bad import can be rolled back.
Recover a report exactly as it was two weeks ago after realizing a manual correction was actually a mistake.
Wearables & Vitals
Apple Health and Health Connect data becomes part of the same picture as your lab reports.
Apple Health & Health Connect sync
Steps, heart rate, sleep, blood oxygen, and more are pulled in on a schedule and stored alongside your manually logged vitals — never merged or conflated with them.
See your resting heart rate trend on the same dashboard as your latest thyroid panel without exporting anything by hand.
Wearable-symptom correlation
Statistically compares wearable metrics like step count and sleep duration against your symptom journal to surface real, calculated correlations.
Confirm — with your own numbers, not a hunch — that your low-activity days are genuinely linked to your fatigue entries.
Family & Multi-Profile
Manage health records for parents, children, or dependents with the same rigour as your own.
Isolated multi-profile records
Each family member gets a fully separate encrypted profile with its own cloud folder and workbook — nothing is ever mixed between profiles.
Track your ageing parent's chronic condition and your child's growth chart in the same app without either record ever bleeding into the other.
Family health dashboard
A single overview surfaces which family members have pending reports, upcoming appointments, or values that need attention.
Check once a week whether anyone in the household has a lab result or appointment that needs following up on.
Health Score, Goals & Predictive Insights
Turn raw numbers into a clear, ongoing picture of where your health stands and where it's heading.
Composite health score
A weighted 0–100 score, broken down by category — anaemia, liver, kidney, lipids, thyroid, and more — computed from your latest results, not a generic questionnaire.
Get one honest number to track quarter over quarter alongside the detailed category breakdown behind it.
Predictive test scheduling
Learns the cadence of your recurring tests and preventive-care guidelines to suggest when your next check-up is genuinely due.
Get a nudge that your annual full-body panel is coming up before it's overdue, based on your own testing history.
Health goals & habit tracking
Set concrete health goals with target dates and track supporting daily habits with streaks, all backed by your real logged data.
Track a 90-day goal to bring your fasting glucose down and see the daily habits that are actually moving the needle.
Personalised risk engine
Combines your vitals, lab trends, symptom frequency, and profile factors into category-level risk scores with plain-language explanations.
Understand in plain language why your cardiovascular risk category shifted this quarter, not just that a number changed.
Compliance & Your Data Rights
Built around India's Digital Personal Data Protection Act, with HIPAA, GDPR, and CCPA principles applied throughout.
Granular consent manager
Core local processing, AI document processing, cloud backup, and wearable sync are each independently opt-in, revocable at any time from a single screen.
Use VitaLog fully offline with AI and cloud sync switched off, then turn cloud backup on later the moment you're ready.
Right to access, correct & erase
A live summary of every category of data held about you, plus one-tap correction and full account/data deletion, in line with statutory data-rights requirements.
See exactly how many reports, messages, and records are stored about you, then delete all of it permanently in a single confirmed action.
Grievance redressal
A dedicated in-app channel routes privacy or data concerns directly to a named grievance contact, with every request logged locally for your own records.
Raise a data-handling concern through a clear, documented channel instead of hunting for a generic support email.
Emergency & Everyday Life Tools
Practical tools for the moments that matter most, and the ones that add up over time.
Emergency health card
A shareable card with blood group, allergies, active conditions, medications, and emergency contacts, generated automatically from your existing profile.
Hand a paramedic the critical facts in seconds during an emergency, without them needing to unlock your phone or dig through records.
Medical expense tracking
Log consultations, medicines, lab tests, and hospital bills by category, with monthly and yearly breakdowns for reimbursement or budgeting.
Pull together a full year of medical spending by category in minutes when it's time to file an insurance claim or tax deduction.
Notifications that matter
Medication reminders, refill alerts, critical-value alerts, and periodic checkup reminders — all computed locally from your own schedule and stock levels.
Get reminded a week before a prescription runs out, calculated from your actual dosage and quantity, not a fixed generic countdown.
