Track Your Lab Results.
Own Your Health Data.
A premium macOS app that imports your lab PDFs, tracks 900+ biomarkers, and generates doctor-ready reports. Store everything locally on your Mac for ultimate privacy — or sync via iCloud across all your Apple devices. You choose.
Your Data, Your Choice
LabsLedger gives you full control over where your health data lives. No compromises.
100% Local Storage
Keep everything on your Mac and nowhere else. Your data never touches a server — we literally cannot see it, even if we wanted to. Perfect for those who want absolute privacy.
- Zero data transmission
- Sandboxed on-device database
- No cloud account required
- Works fully offline
iCloud Sync
Seamlessly sync your lab data across all your Apple devices through your personal iCloud account. SierraNova Labs still has zero access to your data — only your Apple ID does.
- Sync across all your Macs
- Your personal iCloud — not our servers
- Automatic background sync
- Switch anytime in Settings
Both options keep your data out of our hands. Switch between local and iCloud storage anytime — no data loss, no hoops to jump through.
Everything You Need to Track Your Health
From PDF import to doctor reports, LabsLedger gives you a complete lab result management system.
Drop a PDF. Review Your Data.
Import lab reports and extract biomarker values using Apple's on-device Vision OCR — not cloud AI — so your PDFs never leave your Mac. Optimized for Quest and LabCorp. Results vary by format, so you'll always review in a split-pane view before saving.*
Learn moreYour Green Score
See your overall health snapshot at a glance. The Green Score shows what percentage of your biomarkers fall within reference ranges — and highlights what needs attention.
Learn moreDoctor-Ready Reports
Generate professional Doctor Visit Reports with attention items, trend data, and category breakdowns. Save as PDF or print directly — your doctor will love it.
Learn moreWe Never See Your Data. Ever.
Whether you store locally or sync via iCloud, your health data never touches our servers. Local mode keeps everything sandboxed on your Mac. iCloud mode uses your personal Apple account — we still can't access it. Either way, your data belongs to you alone.
How It Works
Three simple steps from PDF to actionable health insights.
Import Your Lab PDF
Drop a lab report PDF and LabsLedger extracts biomarker values using on-device OCR — no cloud, no AI, no data sent anywhere. Optimized for Quest and LabCorp. Results vary by format — you'll always review before saving.*
Review & Confirm
See parsed results side-by-side with the original PDF. Verify accuracy with confidence scores, edit values, and add manual readings.
Track & Report
Watch your biomarker trends over time with interactive charts. Generate professional doctor reports with a single click.
*OCR may not capture all biomarkers and accuracy varies by lab format and PDF quality. Always review parsed results and add any missing values manually. Manual entry is available for any lab format.
Intelligent PDF Parsing
All parsing happens on your Mac using Apple Vision OCR — your PDFs are never uploaded anywhere. Review confidence scores, correct any values, and save — all in a clean split-pane view.
Professional Reports for Your Doctor
Generate comprehensive Doctor Visit Reports with attention items, trend comparisons, and category breakdowns. Print or save as PDF.
