How it works

Sense. Think. Act.

Every minute, HealthKit hands Aevo a fresh signal. The engines argue. The app shows you one move.

/01 — SENSE
HealthKit reads you.
Sleep quality, heart rate variability, resting HR, active calories, steps, and body temperature — pulled automatically, no manual logging.
HRV PEAK 6:00 12:00 22:00
/02 — THINK
14 engines.
One verdict.
Circadian rhythm, caffeine decay, sleep quality, hydration — they run in parallel, then the coordinator blends them into a single 0–100 score.
SIGNAL VERDICT
/03 — ACT
One small move.
Drink 350ml. Walk 4 minutes. Eat now. Sleep at 23:10. Each suggestion is sized to the next 5 minutes and shows you the exact energy delta.
NEXT MOVE · 14:42
Drink 350ml.

The App

Your energy,
narrated.

One number on the home screen — 0 to 100 — that means something real. Tap it to see why. Then do one thing. Scan one meal. Ask one question. Close the app.

AI COACH
Knows your data.
Speaks plain English.
Powered by GPT-4o. Knows today's HRV, this week's sleep, your caffeine curve.
Why am I so tired at 3pm?
Your HRV dropped 18% after lunch. Combined with the post-caffeine curve, your energy peaks at 13:40 — you're in the natural dip window. A 4-minute walk would add ~9 points.
Should I have another coffee?
Not before 15:30. It would cost you ~22 min of sleep tonight based on your pattern.
MEAL SCAN
Camera in.
Macros out.
Point at any meal. AI identifies it and gives you calories, protein, carbs, fat — no typing.

Tuesday, 14:42.
Afternoon dip avoided.

Aevo spotted the dip 22 minutes before it landed. The fix — a 4-minute walk and 350ml of water — cost nothing and saved the afternoon.

Under the hood

Fourteen engines.
One verdict.

Most apps throw raw numbers at you. Aevo runs a parliament of models — circadian, decay, recovery, memory — and only shows you the conclusion.

/01 CIRCADIAN
Two-process model
Predicts your biological energy floor by hour, calibrated to your chronotype and wake time.
/02 ADAPTIVE
The battery score
Multiplicative blend of every signal into a single 0–100 number. Sleep is a multiplier, not an addend.
/03 DECAY
Non-linear drop
Models the organic curve of energy between meals and actions — not a flat line.
/04 PREDICTION
Forecast next 8h
Plots the energy curve given your current plan. See the dip before it lands.
/05 CAFFEINE
Half-life decay curve
Tracks caffeine absorption, peak, and crash. Tells you exactly when the next coffee helps vs hurts sleep.
/06 FEEL-OFF
Cause-finder
Traces back through your last 4h to the most likely culprit — hydration, sleep debt, caffeine, or food.
/07 MEMORY
Long-arc patterns
"Coffee after 4pm costs you ~40 min of sleep." Learned from your own weeks, not averages.
/08 NUTRITION
Meal impact model
Macros and meal timing affect energy differently by person. The engine learns your response curve.
/09 HRV + SLEEP
Recovery quality
HealthKit HRV and sleep stages feed the recovery multiplier — bad sleep caps everything else.
/10 SMART TASK
Next best move
Picks the single action with the highest ΔEnergy for your current moment.
/11 JET LAG
Travel recovery
Detects timezone shifts and adjusts the circadian baseline. Tells you when to expose to light or sleep.
/12–14 + MORE
Vitamin gaps · High stakes · Coordinator
Micronutrient tracking, high-stakes day optimization, and the master coordinator that runs them all.
