Note every day. Look after your family. Snap, say or scan a meal and AI logs it in seconds, from about 447,000 foods. Meds, water, sleep and lab reports too.
Snap, say or scan: AI logs a meal in seconds. It recognizes each dish and ingredient, and the nutrition comes from about 447,000 foods: official food tables of 8 countries and regions, Linnea's standard dishes and packaged foods with their label values.
Measured, with the method in the app: 99% of 2,092 everyday foods appear in the first 3 search results, and a meal described in words or by voice lands at a median calorie error of 9.5% (480 test meals in 8 languages, October 2026).
Meds, water, sleep, mood, vitals and lab reports too, with a daily score, reminders and a family of up to 6, free.
AI logging in a few taps
Take a photo, type or speak, and AI lists each dish and ingredient to check, with calories, protein and 20 more nutrients. Scan a barcode or nutrition label, pick a recipe, or log yesterday's breakfast again in 3 taps. Also log medications, supplements, water, sleep, workouts, mood, symptoms, weight, blood pressure, glucose and temperature, from widgets, Siri or Apple Watch.
The food database
About 40,000 foods and dishes from official tables, including about 3,000 standard dishes computed ingredient by ingredient, and about 407,000 packaged foods from USDA data. A dish computed from its ingredients and weights lands at a median calorie error of 5.7% (400 weighed Nutrition5k dishes). A photo shows the portion it assumed, so you can change it. Each figure and its method is under Linnea's strengths.
One score a day
Your Linnea score brings together sleep, intake, activity, well-being and routine, leaves out any area with no data and says how many it used. Tap it to see what moved it. Ask Linnea answers from your entries only.
Plans and reminders
This Week's Meal Plan picks dishes from your recipes and the Linnea dish library, with a shared Grocery List. Medication, supplement and water reminders show a fixed message such as "Time for your medication", never a name or dose; mark a dose as taken from the notification or the Lock Screen.
Health records
Scan a paper lab report and every value is recognized on your device, without a connection; you check each one before saving. Each test is shown over time with the reference range from the report; Linnea doesn't interpret results. Records are encrypted on your device before upload, and the server stores only encrypted data. Records are free.
Your family
Up to 6 people, each with their own account and choosing what to share. For a child, or a parent without a phone, you keep the log and records. With a member's consent, Linnea tells you when a scheduled medication hasn't been logged. All free, except the Family Menu.
Apple Health and Apple Watch
Linnea reads sleep, activity, workouts and heart rate, and saves what you log, keeping edits in sync. Medications in Apple Health are read-only for other apps; Linnea reads them only to avoid duplicates. On Apple Watch, log water or a meal by voice and mark a medication as taken.
Privacy
Raw Apple Health data never leaves your device; only daily summaries are uploaded. Health details stay out of crash reports and analytics. Export or delete your data at any time.
Linnea Premium
Logging, the food database, barcodes, scores, reminders, records and saving to Apple Health are free. Premium raises the limits on AI logging and search, Ask Linnea and meal plans, and adds What's for Dinner, the Family Menu, the AI weekly summary and workout ideas. Daily fair-use limits apply.
Linnea is not a medical device and does not give medical advice. It doesn't diagnose or recommend treatment, and it never suggests changing a medication or dose.
Linnea Premium is an auto-renewable monthly or yearly subscription charged to your Apple Account. It renews unless auto-renew is turned off at least 24 hours before the current period ends; manage or cancel it in your Apple Account settings.
