- Free: build the habit with daily tracking, core charts and today's pulse
- Essential: deeper trend clarity, comparisons and more ways to track progress
- Plus: cross-sense explanations ("show me why"), deeper interpretation and more advanced insights
- PRO: clinician-ready reports and the lowest-friction workflow for serious health management
AI features like meal analysis, lab scanning and chat usage vary by plan.

FoodSense camera upgrade:
- Improved meal photo capture reliability.
- Updated barcode scanning for smoother product lookup and steadier scans.
- Better camera startup, focus handling, and low-light behavior.
Daily insights and hub summaries now expire on the user's local midnight, so users in different time zones see day-based data roll over at the right time.
Fast-changing data such as activity, heart rate, steps, meals and medication-related updates now uses shorter freshness windows.
Cache invalidation is coordinated across Home, FitSense, FoodSense, MedSense and the backend services that feed them, reducing cases where users needed to pull down individual screens to force the latest data.
Hubs, AI summaries and insight caches now store timezone-aware cache identities, preventing UTC-based rows from masking the correct local-day result.
Food, auth, wearables and hub APIs were redeployed with safer cache-control behavior and more consistent refresh handling.
Session refresh handling was validated so signed-in users keep working cleanly after backend cache updates.
Also included: stability and reliability improvements for app startup, health data display, and cross-screen freshness.

Users can reach Food vs burn from the FoodSense menu as its own entry point.
The new screen supports a same-day check as well as longer windows, so users can quickly compare today’s intake vs burn or look at broader patterns.

Navigation inside tabs is more natural, so opening screens from the section you’re already in should feel less jumpy and more seamless.
FitSense body logging is easier: the form can prefill your latest saved weight, optional measurements remain optional, and weight selection now uses a clearer wheel-style picker instead of manual typing.
FoodSense meal details are more useful: you can now open protein, carbs, and fat breakdowns to see which ingredients contribute most to each macro, with clearer totals and percentage-of-total views.
FoodSense review is easier to finish because the save/update action now stays pinned at the bottom, so you do not need to scroll back down to confirm a meal.

Made GPS location refresh smarter when GPS mode is enabled: the app now refreshes location quietly on the first app run of the day and retries later if a GPS fix is not available, while manual location still stays available.
Polished FoodSense meal capture by keeping camera flow in-app and improving camera behavior, especially on iPhone, with better focus/preview handling.
Improved barcode and meal naming so scanned products are more likely to keep the real product title instead of falling back to something too generic.
Improved meal summaries, favorites, and review flow so meals without an AI summary still show a useful fallback summary, favorite meals keep more context, and ingredient matching during review is more reliable.
Added some small accessibility and UI polish, including easier-to-read multi-line action buttons and better tap targets in prompts and subscription actions.
FoodSense barcode scanning now works better on small packaging, especially on iPhone, with improved close-up camera behavior and clearer on-screen guidance.
You can now turn the camera light on or off directly in both the barcode scanner and the meal/label camera, which helps in darker environments.
Label mode now captures ingredient lists and nutrition labels more clearly by favoring close-up framing and higher-quality photo capture.
Camera focus and scan timing were tuned to reduce blurry or premature reads, so scans should feel faster and more reliable once the code is in focus.
FoodSense barcode scan now lets you manually add a missing product or edit product details when barcode information is incomplete.
You can save product name, brand, ingredients, allergens, traces, and key nutrition values, and the app will use your saved version right away.
Your saved barcode details are kept on your device first, so they can still be used while shared/community sync is pending or even if online lookup fails.
Product results now show clearer messaging when details come from your saved version or from community-provided data.
General reliability improvements were also made behind the scenes for barcode data sharing and workout session syncing
FoodSense meal titles now behave more intelligently. Automatic titles stay in sync with the selected meal time, but custom titles you type are preserved.
Saved meal drafts restore more cleanly, including better handling of suggested meal names based on the meal time.
Editing ingredient amounts is quicker because tapping the amount field now focuses it properly and selects the current value so it is easier to replace.
