Calenta notices your meals from your Apple Watch — no food diaries, no barcode scanning, no guilt spiral. When you eat, it asks. You answer with one tap: Small, Medium, or Large, at calorie values learned from you.
Your body responds to every meal. Calenta reads that response from your Apple Watch — heart rate and wrist motion, processed on your devices.
One notification, three buttons. Tap the size and you're done — sized to your own meals, not a database average.
Every answer tunes Calenta to you: your meal sizes, your patterns, your body. It gets sharper the longer you wear it.
Your health data is processed on your iPhone and Apple Watch and stays there. The App Store version of Calenta collects nothing — see the privacy policy.
