Full Localization Pass Weekday headers, time axes, export labels, subscription copy, meal management dialogs, and AI prompts now follow the selected app language Cleaned up remaining hardcoded Chinese strings across History, Correlation Analysis, and Settings Meal Entry Improvements Meal type selection is now icon-first and shows a short text hint after tapping Both meal creation and meal editing support camera and photo library entry points with more reliable photo picking Meal management dialog labels are now localized AI Workflow Upgrades The AI food-analysis prompt is now localized, so copied prompts match the current language Subscription-based AI correlation analysis copy and price display now use runtime data instead of hardcoded text Upgrade prompts and action labels are clearer for subscribed and unsubscribed users Calendar & Chart Fixes Weekday headers in History and Insight calendars now respect the app language Hour labels and timeline formatting are localized, avoiding mixed-language labels History stats and export content are now consistently localized

Total Calendar & Metrics Upgrade The calendar bottom value label now supports displaying Max Glucose, Min Glucose, Avg Glucose, Variability, Time-In-Range, and Calories Burned Fixed an issue where the past dates wouldn't display numeric values (showing "-") when filtering by "Exceed Count" Blazing Fast Performance Introduced a memory cache layer for Apple HealthKit activity queries: Navigating back to previously viewed dates in Correlation Analysis and History View is now practically instantaneous without draining extra battery Engineered a dedicated 3-day wide-angle cache track specifically for the swipeable Correlation Analysis chart, keeping your swiping buttery smooth UI Overlap & Layout Fixes Repositioned core navigational elements (like Calendar Close & Clear Filters) strictly inside the native Toolbar navigation layers, completely resolving overlaps with the TrueDepth camera / Dynamic Island The massive Calendar in the History Screen is now fully collapsible to reclaim all that screen real estate for your actual chart readings Chart Precision & Readability The "Green Safe Zone" background inside the History View chart now accurately shrinks or stretches to match your exact personalized Target bounds defined in Settings Eliminated a fallback bug that incorrectly labeled certain normal metabolic ranges (like 7.2 mmol/L) as "High" (Orange dots) Added clear visual color legends underneath all charts so you know exactly what every dot represents at a glance

Correlation Analysis Chart Improvements Fixed calorie bars being clipped at the top — peaks now display fully Y-axis dynamically adapts to actual data range, eliminating excessive empty space Gesture hint text moved below the chart so it no longer covers the X-axis labels Fixed single-finger selection showing incorrect glucose values when CGM delay compensation was active Gesture Interaction Fixes Rewrote two-finger pan and pinch-to-zoom gestures to work reliably inside scrollable pages Two-finger drag to pan the timeline, pinch to zoom the time window (2h–24h) CGM Delay Compensation Your CGM delay offset is now saved automatically — no need to re-configure every time you open the app Activity Data Loading Calorie/activity data now loads 3 days (±1 day around selected date), so dragging the chart across midnight no longer loses calorie bars High Glucose Event Tracking Rewrote the low-point detection algorithm: now looks back up to 90 minutes to find the true start of the entire rising wave, including cases where two consecutive rises are separated by a brief dip Short plateaus or minor dips between two rising segments are now correctly grouped into a single high-glucose event Glucose Trend Localization Added 9 missing translation keys for Japanese and Korean (glucose curve, update time, variability, post-meal peak, etc.) Glucose Trend Chart X-Axis Fix Reduced x-axis label count to prevent overlapping and overcrowding Unified short time ranges (3h/6h/12h/24h) to display HH:mm only, avoiding long label text Simplified Event Types Reduced event types from 10 to 3: Meal, Exercise, and Custom for a cleaner experience Event Markers on Correlation Chart Meal, exercise, and custom events now appear as colored time-range bars on the chart, making it easy to see how events correlate with glucose changes Tapping an event area on the chart shows the event type name Auto-Refresh Record Details Changing start/end time in record details now automatically refreshes glucose and activity data — no manual refresh needed
