Your day, decided
Open Arete and know exactly what today asks of you.
Readiness, the recommended workout, calorie and macro targets, hydration, recovery, and your next meal — one screen, understood in five seconds. Details are one tap away, never in your face.
Readiness
A transparent score with the factors behind it — never a mystery number.
Today's workout
Adapted to your fatigue, schedule, and equipment.
Fuel targets
Calories and macros that shift with training load.
Recovery action
One concrete thing to protect tomorrow's session.
Food photo analysis
A photo of your plate becomes a labeled estimate.
Point your camera at a meal. Arete identifies the items and returns calories, macros, and nutrients — every number shown with a confidence level and an editable serving size. Estimates are estimates, and we say so.
Photograph the meal
Snap or upload. Multiple items, sauces, and drinks are handled.
Identify & estimate
Items recognized, portions estimated, calories and macros returned.
See the breakdown
Protein, carbs, fat, fiber — each with a confidence label, not false precision.
Correct & apply
Adjust servings; the plan updates your remaining targets for the day.
Photo estimates are approximate and improve as you correct them. Not a substitute for precise measurement when it matters.
Training that adapts to today.
Programming responds to your goals, history, schedule, fatigue, recovery, and available equipment. Every recommendation comes with a reason, a confidence, an alternative, and controls to adjust — complete it, reduce intensity, swap to mobility, or rest.
A recovery engine you can read.
Sleep, resting heart rate, HRV where available, soreness, training load, and a quick check-in combine into a readiness band — with the contributing factors, data completeness, and confidence shown. Measured, self-reported, and estimated data are always distinguished.
Health data connections
Bring your data together — honestly.
Arete is built to unify workouts, sleep, heart rate, HRV, steps, energy, body measurements, and lab records. Native Apple Health and wearable sync arrive through the Arete iOS app; the web app never claims access it doesn't have.
Performance insights
Insight, not decoration.
Charts earn their place by changing what you do next.
Who Arete is for
For people who want a system, not another tracker.
Athletes & former athletes
Rebuild structure and progression without a coach on retainer.
Busy professionals
A five-second daily plan when time and attention are the constraint.
Hybrid & strength lifters
Balance lifting, running, and recovery in one adaptive system.
Tired of fragmented apps
Nutrition, training, recovery, and health data — finally in one place.
Trust & science
Recommendations you can interrogate.
Every score is built from named inputs, shown with confidence and limitations. We separate education from medical advice, and escalate when it matters.
Named data sources
No black-box single number.
Confidence on estimates
We never fake precision.
Safety guardrails
No dangerous restriction or training through injury.
Private by design
Health data is never sent to ad platforms.
YOUR NEXT LEVEL
NEEDS A SYSTEM.
