Someone reads it back
Steps, sleep, workouts and weight come back as one sentence about today, not another chart.
Honest comparison
Kata vs Apple Health.
Apple Health is the most complete free health store on any phone. What it does not do is coach. Kata reads what Apple collects and does something with it.
The verdictThe best free health store there is. And the one thing it never does with your data.
First, fairly
Apple Health at a glance.
What it is for
The free iPhone app and data store that everything else writes into, filled mostly by the Apple Watch.
What it costs
The Health app is free and no health feature needs a subscription. Apple Watch SE 3 starts at 249 USD, Series 11 at 399 USD and Ultra 3 at 799 USD. Fitness+ costs 9.99 USD a month or 79.99 USD a year and buys content, not analysis.
Where it is strongest
Cleared screening at no extra cost: ECG, atrial fibrillation history, sleep apnea and hypertension notifications on hardware you already wear.
Who it suits
Anyone who wants a neutral free store every app can write to, plus regulated screening from the watch.
The difference
What changes with Kata.
One system, one score
Food, training, labs, supplements, water and mood in one place, pulled into a single day score.
Stays on your device
Your logs, chats, photos and Kata's memory of you live on your phone, not on our servers.
Side by side
Row by row.
A gray mark means possible, but not on its own.

Why Kata
Three reasons, not thirty.
One system
Food, training, sleep, supplements, labs and mood in a single place.
It decides
Not a dashboard you read: a coach that says what today should look like.
It stays yours
Your logs, chats, photos and Kata's memory live on your device.
Honestly
When Apple Health is the better choice.
For screening, Apple wins outright. ECG, atrial fibrillation history, sleep apnea and hypertension notifications are cleared features no coaching app can or should claim, and they cost nothing beyond the watch. Keep them.
In short
What, how and why.
- What
- Kata is the coach that Apple deliberately does not ship.
- How
- It reads activity, workouts, sleep, heart rate and HRV, body measurements and nutrition from Health, then decides what to eat and train.
- Why
- A Health app full of numbers nobody reads back to you is a filing cabinet.
One coach. Your whole picture.

Questions
Asked and answered.
Does Kata read Apple Health automatically?
Yes, on iPhone. Connect it once and steps, active energy, workouts, sleep, weight, heart rate, HRV, body measurements, nutrition and water fill your day in on their own. Anything you log by hand wins over a synced value, so your corrections stick.
Can I log food in Apple Health?
Not with Apple's own tools. The Health app stores nutrition data types but ships no food database, no barcode scanner and no meal log. In Kata you say what you ate, or photograph it with Kata Plus, and it becomes calories and protein.
