Quoi de neuf dans la dernière version ?
Dynamic Layout Detection
• Automatic column detection — Replaced the fixed-layout with a dynamic layout detection engine. The app now analyses each PDF page's text density to find the inter-column gutter, adapting automatically to both new and old-style Aktiia reports.
• Improved right-column scanning
Scanning Accuracy Improvements
• Image preprocessing pipeline improvements
• High DPI rendering — Column regions are now be rendered at 3x resolution for better OCR accuracy
• Deduplication logic improvements
Edit Blood Pressure Readings
• In-app editing — Tap any individual reading to edit its systolic, diastolic, and heart rate values. Changes are committed to SwiftData and synced to HealthKit automatically.
• Aggregate recalculation — Monthly mean, min, and max are recalculated when a reading is edited.
Outlier Detection & Review
• Outlier review sheet — Readings flagged as statistical outliers are now presented for review. Users can restore or discard individual readings, or restore/discard all at once.
• Auto-show after scan — The outlier report automatically appears after a scan when new outliers are detected (toggleable in Settings).
• Auto-clean on report delete — Rejected readings are automatically removed when their associated report is deleted.
New Debug Mode (for support purposes)
• Debug OCR view — Accessible via Settings → Debug → Enable Debug Mode. Shows the full OCR pipeline: detected text observations with confidence colour-coding, column boundary overlays, preprocessing comparison, and per-column scan results. Designed for troubleshooting scanning issues.
• Column boundary visualisation — Cyan rectangles show where the dynamic layout detector placed column boundaries, with zoom and pan support.
UI Improvements
• Avg/Min/Max display — Fixed font scaling and wrapping issues in the aggregate display on the report list. Blood pressure and heart rate now use a monospaced font for consistent alignment.
• Portrait/landscape rotation fix — Resolved a crash when rotating from landscape to portrait in the readings view.
• Settings reset — Added a "Reset to defaults" button in Settings.
