What's new in this update:
• Shopping list: a ready-made shopping list built from your weekly meal plan. Every ingredient for the week, grouped by aisle, so you can simply check things off as you shop, for the whole week or day by day.
• Inflammation Management Score: a single score from 0 to 100 shows how well your inflammation is managed, right on your home screen, along with your target, an estimated timeline, and milestones to reach.
• Daily stiffness check-in: log how long your morning stiffness lasts and how much it affects your day, so your score always reflects how you really feel.
• Redesigned onboarding that adapts to your condition, so your plan feels personal from the very first day.
• A cleaner home screen, refreshed design, and many fixes for a smoother, faster experience.
