Added Elder Mode and blood pressure averages, plus nearly 150 more Taiwanese foods** • Added Elder Mode: a simplified screen for a family member, with just three actions — log a usual food, see today, log water — no search, no menus. An on-screen hint shows that a 5-second press-and-hold exits • Elder Mode's usual items are organized by meal (breakfast/lunch/dinner/snack), default to the current time of day, and can also be switched manually. Beyond individual foods, a saved meal set can be added too, logging the whole set in one tap • The blood pressure chart now has a Range / Average / Both switch: see each reading's range, an average line per period, or both overlaid. A period-average summary appears below the chart • Added 64 Taiwanese dishes, such as Tainan beef soup, stir-fried duck blood with pork intestine, angelica duck soup, Hakka stir-fry, eel yi noodles, and tube sticky rice • Taiwanese noodles greatly expanded: 33 new varieties including beef brisket noodles, braised pork noodles, shredded chicken noodles, pork chop noodles, and rice vermicelli with meat soup — each in small and large bowls; existing noodles also gained large-bowl entries • Over 300 more foods in the database: vegetarian dishes, Taiwanese home cooking, and restaurant chains such as Thai Town (瓦城), Taoban (陶板屋), Zhujian (築間), Juan Tofu (涓豆腐), Sushiro, Kura Sushi, Ay-Chung Noodles (阿宗麵線), Du Hsiao Yueh (度小月), Haidilao, Pike Chicken (派克雞排), and Louisa Coffee (calories are estimates); plus Korean, Thai, Sichuan, Hong Kong dim sum, Vietnamese, omurice, sizzling-plate steak sets, Taiwanese bakery, Hakka and outlying-island specialties, night-market snacks, fruit, snacks, supplements, festive foods, traditional desserts and drinks, and millet and Shaoxing wine • "Recent foods" in food search now remembers separately per meal — foods like bubble tea or fried snacks that show up across lunch, dinner, and snacks can now appear in more than one meal's recent list

**Fixed a slow-loading Fitness Progression view, added Chinese condiment add-ons** • Fixed the Fitness Progression view (treadmill, swimming, and other workout trend analysis) taking 20-30 seconds to load the first time it's opened — it's noticeably faster now • AI report generation now runs asynchronously and automatically scrolls to the preview once the report is ready • Added Chinese condiment add-ons to food search (chili oil, sesame oil, ground peanut powder, garlic chili sauce, sha cha sauce, sweet chili sauce, thick soy sauce, garlic/ginger paste), adjustable by spoon count • Corrected condiment calorie values using verified nutrition sources — some items had been overestimated in the earlier draft figures

Heart Rate Zones • The Heart Rate and Resting HR detail pages now show your personalized Z1–Z5 heart rate zones, calculated using the Karvonen formula from your age and resting HR. Tap any zone to see a plain-language explanation and weekly training time recommendation. • Each workout in today's summary now shows a zone badge (e.g. Z3 138 bpm) so you can see at a glance whether your ride or run was a warm-up or a solid aerobic effort. • The workout history page for each activity now includes a zone distribution chart below the existing graphs — showing how your intensity was spread across zones for the selected period, with a plain-language verdict on whether the intensity was sufficient. • The Fitness Progression heart rate comparison now shows which zone each half landed in. If your zone shifted between periods (e.g. Z3 → Z2 at the same effort), it tells you what that means for your aerobic fitness. • Fixed an issue where the zone badge sometimes didn't appear on today's workout card.
