Most food trackers hand you a number whether or not they actually have one. Asira Core tells you when it doesn't know. It's a calorie tracker and a health tracker at the same time. It reads your Apple Health data and what you ate, puts both on one page, and tells you what to do about today. Four Daily Scores Flow, Sleep, Intensity and Stress, built from your Apple Health data. Tap any of them and you'll see the readings underneath, so you can tell why the number moved. Log a Meal in Seconds Snap a photo, scan a barcode, or just describe it. Calories and macros get checked against USDA FoodData Central and Open Food Facts, and every food gets a Nutrition Score. You choose what gets logged. Targets Built Around You Calories and macros set from your body, your goal and the pace you picked. Change any of it and the plan recalculates. Coaching from Ari Ari reads your day and gets specific: which night cost you REM, what yesterday's hard session is still charging you, whether an hour earlier tonight would win most of it back. Your Morning Vitals Resting heart rate, HRV, respiratory rate and wrist temperature, each measured against your own baseline. The arrow shows which way you moved, and the color tells you whether that's worth your attention. Weight and Water Log your weight and watch the gap to your goal close. Water is one tap. On Apple Watch Check your daily scores and start workouts from the companion Apple Watch app. Trends Over Time Sixteen metrics charted across weeks and months, so one odd day doesn't read as a trend. Reminders You Control Pick how often, or switch them off entirely. Synced to Your Account Your log follows you, not the phone you logged it on. Before You Start You'll need an account, because your data syncs across your devices. The four daily scores come from Apple Health, so if you're new to it, or you don't wear a watch to bed, those screens will say they're still calibrating rather than invent a score. Food, water and weight work on their own. With your permission, food photos, descriptions and Voice Log audio are sent through Asira's own server to OpenAI to help log meals. Your name, email and Apple Health data are not included in the requests sent to OpenAI. You can decline AI processing and continue using the app's other features. Barcode lookups use Open Food Facts. Asira Core is not a medical device. It does not diagnose, treat, cure, or prevent any condition, and it is not a substitute for advice from a clinician. Asira+ is an optional auto-renewing subscription ($9.99/month or $99.99/year in the U.S.; prices vary by region). Eligible new accounts receive 7 days of Asira+ access without a purchase, payment details, or an automatic charge. After that access ends, the account returns to the free plan unless you choose to subscribe. Paid subscriptions are charged to your Apple Account at confirmation of purchase and renew unless cancelled at least 24 hours before the current period ends. Manage or cancel in your Apple Account settings. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://asiracore.com/privacy
