Açaí/For biohackers
Quantified Self

Nutrition tracking for biohackers

You already measure HRV, glucose, sleep stages, and VO2 max. The nutrition layer is usually the gap. Calorie counters miss everything interesting. Açaí fills the gap with 245 micronutrients per meal and weekly deficiency modeling that actually correlates with what your wearables are reading.

Correlations

The wearable is telling you something. So is the plate.

Most nutrition apps can’t answer why your HRV tanked on Tuesday. Açaí can, because the data was on the plate three meals earlier. A few common patterns we surface:

Wearable signal
HRV dips
Nutritional hypothesis
Low magnesium, low potassium, or excess sodium in the prior 48h
Wearable signal
Poor sleep
Nutritional hypothesis
High caffeine after 2pm, low glycine, or low vitamin B6
Wearable signal
Afternoon crashes
Nutritional hypothesis
High glycemic load at lunch, low chromium, low B-complex
Wearable signal
Slow recovery
Nutritional hypothesis
Low leucine, low zinc, suboptimal omega-3:omega-6 ratio
Wearable signal
Brain fog
Nutritional hypothesis
Low choline, low DHA, dehydration
Wearable signal
Brittle nails or hair
Nutritional hypothesis
Low biotin, low iron, low silica, low sulfur-containing amino acids

Correlation, not causation. Açaí surfaces the pattern. You run the n=1 experiment.

The stack it belongs in

Designed to sit next to your other instruments

Açaí writes nutrients to Apple Health, which means the same layer pulling your HRV, sleep, glucose, and recovery now has micronutrient intake as a correlated input. If you use Oura, Whoop, Levels, Eight Sleep, or anything that reads from Apple Health, the data is already downstream.

What you get is a full stack: the body output (HRV, glucose, recovery), the behavior input (nutrition, sleep timing, training load), and a model that lets you notice when the two disagree. That’s the definition of a useful biohacking tool.

No fasting guilt, no daily streaks designed for habit formation, no coach yelling at you. Just dense data and a clean interface that doesn’t waste your attention.

Add the missing layer.

Your wearables already measure the output. Açaí measures the input with 245 data points per meal.
