Science and evidence

How the insight engine decides

The insight engine runs on your iPhone and follows fixed rules, so the same data always produces the same insight. An AI model never decides an insight.

• Your baseline comes first. The engine keeps a rolling picture of your own values: 28 days for wearable metrics and a longer window for labs. It judges each new reading against that picture before the population range.
• A link needs data. To connect something you do with something you measure, the engine looks back 90 days and needs at least 14 nights, with at least four on each side of the comparison. It names a link only when the correlation reaches 0.3 and the effect is large enough to matter, such as 3 ms of HRV. With enough data and no effect, it says there is no clear link yet.
• The links it tests. Late meals against the next night's sleep score and HRV. Alcohol against HRV, resting heart rate and sleep score. Caffeine timing against sleep score and time to fall asleep. Yesterday's training load against today's readiness.
• A correlation is a correlation. Every note calls a link what it is. Testing a change on yourself is how you learn what causes what.
• Safety thresholds are absolute. A blood pressure reading at or above 180/120, the ACC/AHA crisis threshold, goes to the top of your Action Center with what to do next, whatever your baseline or protocol says.

Lab results

A frontier AI model reads each value, unit, date and reference range from a photographed report or a PDF. AumniVIDA gives every result a standard identity, so a test stays the same test whichever lab ran it, and converts it to your units while keeping the original beside it. Uncertain extractions wait for your confirmation before they join your graph.

AumniVIDA reads lab reports in English and Finnish, and knows the catalogs of HUSLAB and Synlab in Finland and Quest in the United States.

Reference ranges

Choose the guideline scheme AumniVIDA reads your values against. Every chart shows the named bands and their source.

• Blood pressure: ACC/AHA 2017, ESC 2024.
• Lipids: ACC/AHA, ESC/EAS, and intensive lipid targets with LDL below 1.8 mmol/L (Pro).
• Glycemia: the American Diabetes Association Standards of Care.
• Fitness and body: ACSM bands for VO2max and body fat, and the WHO classification for bone density.

Evidence grading

Every link between a food and a health measure carries a grade from the World Cancer Research Fund and American Institute for Cancer Research framework (2018): convincing, probable, limited but suggestive, or limited with no conclusion.

By default, AumniVIDA shows what rests on convincing or probable evidence. Limited evidence appears only when you switch on Show limited evidence, and it carries its label. AumniVIDA treats four health dimensions as established: cardiometabolic quality, inflammatory potential, gut support and bone health. It marks two as exploratory: oxidative balance and a MIND-style brain-health pattern.

Nutrition

• Meals. A vision model describes what is on the plate. AumniVIDA matches each item to food-composition data, and the nutrients come from that data, never from the AI model. A barcode or a photographed nutrition label identifies a packaged product exactly.
• Diet quality. Each week, AumniVIDA scores your eating against a published index: the Healthy Eating Index 2020, the NNR 2023 food-based score, the Baltic Sea Diet Score, the Planetary Health Diet Index, MEDAS adapted for food logs, or the DASH index.
• Nutrient interactions. Eleven published rules describe how foods eaten together change absorption, such as vitamin C raising non-heme iron absorption and calcium, tea and coffee lowering it. AumniVIDA also tracks the phytate-to-zinc molar ratio against WHO and FAO bands.
• Food and your labs. For 15 biomarkers, including LDL, HbA1c, ferritin, vitamin D, B12, urate and hsCRP, AumniVIDA shows the dietary levers that move them. Between two lab draws, it predicts how your eating should move LDL, triglycerides and vitamin D, and shows the measured change next to the prediction.

Protocols

AumniVIDA writes its protocols from published guidelines and research, such as WHO and AHA guidance and peer-reviewed research, and every protocol cites its sources. Protocols compiled by the community from an expert's published work say so on their badge. A clinically reviewed badge appears only after an independent clinical review.

A protocol can tune the engine's thresholds, set targets for its weekly scorecard and brief the coach. You rank the protocols you follow, and the higher one leads where two differ. Your care team's directives come first, then your own goals, then your protocols. Only a clinician directive tightens a safety threshold.

Medications and food

AumniVIDA checks the medications on your graph against 51 published drug and food rules. The rules come from FDA drug labels and from fact sheets of the NIH Office of Dietary Supplements and NCCIH, and AumniVIDA classifies medications with the WHO ATC system. Examples include simvastatin and grapefruit, warfarin and steady vitamin K intake, MAO inhibitors and tyramine, and the timing of levothyroxine. Every note is informational and points you to your prescriber or pharmacist.

Limits

• Documents can be misread. Confirm uncertain values, and open the source document behind any number to check it.
• A photo cannot reveal hidden oil or butter. Meal values carry ranges where the photo leaves room for doubt.
• Correlations are patterns in your data. They point to what is worth testing, and your next measurement is the test.
• AumniVIDA supports general wellness. Diagnosis and treatment decisions stay with you and your clinician.
