AION · SMART HEALTH DIARY

Your body keeps notes. AION helps you read them

Check in for about 20 seconds a day. See what repeats in your own records. Try one small change, and notice what it does for you.

How it works

Notice. A 20-second check-in: energy, mood, sleep — and only the areas you choose.
Connect. Your assistant counts what shows up together in your own entries, and shows the dates behind every count.
Try. One small program for 7, 14 or 21 days — a bedtime, a walk, a pause at midday.
Feel. Your records show whether it helped. Keep it, adjust it, or try another.

Details

Cycle tracking for those who want it: next period, late status, cycle lengths and regularity. No fertility predictions.
Optional Apple Health import — sleep, steps, active energy, resting heart rate — read-only.
A one-tap check-in from the reminder, the lock screen or Apple Watch.
No account. Your diary stays on your iPhone.
AION is a diary, not medical advice.
