What’s New in Version 1.4 Expansive Viewport Architecture Meridian now dynamically adapts its visual hierarchy for larger and expansive displays. The primary dashboard introduces balanced dual column telemetry, presenting pinned vitals alongside clinical history simultaneously without spatial distortion or truncated metrics. Phenotypic Longevity Modeling Introducing the on device Biological Age engine, grounded in Dr. Morgan Levine’s validated PhenoAge algorithms. Quantify your biological rate of aging, explore longitudinal trajectory models, and analyze biomarker specific longevity contributions with absolute mathematical privacy. Decoupled Master Detail Navigation Medical records now utilize an intelligent split view framework on expansive screens, allowing simultaneous category exploration and granular document review with persistent state continuity. Synchronous Chart Interrogation Kinetic touch interactions across longitudinal biomarker graphs now instantiate crosshairs and analytical tooltips instantaneously at the precise coordinate of tactile engagement. Cryptographic Profile Partitioning Enhanced multi profile architecture enforces strict cryptographic isolation, ensuring family member records and cached clinical indicators remain compartmentalized. Defect Remediation and Structural Polish Resolved edge to edge interface stretching anomalies, corrected viewport typography constraints, and eliminated search bar redundancies on locked states to ensure a serene, distraction free diagnostic experience.

What's New in This Version: Introducing Biological Age & Longevity Intelligence Discover your body's true cellular age directly from your routine blood tests. - Phenotypic Biological Age: Powered by the peer-reviewed PhenoAge model (Yale University & UCLA), Meridian analyzes 9 routine blood biomarkers from your standard CBC and Metabolic panels to estimate cellular age. - Pace of Aging: Track whether you are aging faster or slower than your chronological peer group. - Actionable Longevity Levers: See which biomarkers are actively subtracting or adding years to your biological age, complete with clinical insights. - Longevity Trajectory: Track your biological age evolution across multiple years of blood work with interactive charts. - 100% On-Device & Private: All longevity computations happen locally on your iPhone with zero data leaving your device. Clinical Accuracy & Performance - Smarter Range Evaluation: Out-of-range biomarkers (High or Low) are now instantly prioritized in your Trends summary. - Enhanced Document Ingestion: Upgraded document parsing to filter out lab timestamps and non-clinical metadata. - Fluid Navigation: Modernized search with interactive dismissal and responsive animations. - Stability & Speed: Performance optimizations for large multi-year lab histories and seamless profile switching.

Introducing Batch Import: You can now select and upload multiple lab results, PDFs all at once. Meridian will process them seamlessly in the background. • Smarter Review Process: We've introduced a new, intuitive 3-tier review system. Meridian automatically flags which biomarkers look perfect, and which ones might need a quick human glance, making it faster than ever to verify your records.

Quick Add for Biomarkers You can now manually log individual biomarker readings right from any trend screen. Just tap the new '+' icon to add a reading and customize the reference range. This makes it incredibly easy to keep your history perfectly up to date, even when you don't have a full lab report to scan. Real-Time Data Sync We've completely rebuilt the way data stays synchronized between your Records and Trends tabs. Now, any edits or deletions you make to a record will immediately and seamlessly update across all your charts. UI Changes • Cleaned up the chart reference headers to reduce text clutter. • Updated the MedlinePlus links to match the standard card layout used elsewhere in the app. • Updated a few category icons for better accuracy.

This update brings significant improvements to how Meridian presents your health data, focusing on clarity, accuracy, and a more refined visual experience. Redesigned Dashboard We have completely overhauled the home screen to provide a clearer, more organized view of your health. The new layout highlights your most important recent uploads at the top, and introduces miniature trend graphs to your dashboard cards so you can see the direction of your results at a glance. More Accurate Reference Ranges To provide the most accurate context for your results, Meridian now prioritizes the specific reference ranges provided directly by your testing laboratory. If laboratory ranges are unavailable, the app relies on a carefully curated set of standard clinical fallbacks to ensure you always have a reliable baseline for comparison. Smarter Data Processing We significantly improved our data matching algorithm. The app is now much better at understanding uniquely named or abbreviated markers from different laboratories, ensuring your data is correctly categorized and tracked over time. Refined Visuals and Performance • Updated chart visuals to clearly display the upper limits of reference ranges. • Refined color usage across the app to ensure normal, in-range results are displayed with neutral colors, eliminating any unnecessary visual alarm. • Improved the interface for markers that have limited historical data or non-numeric results, providing helpful context rather than empty charts. • Resolved underlying performance issues that caused animation lag when navigating between complex trend graphs.
