What is Calo One?

Calo One combines sleep, activity, and nutrition in one app, providing clear scores and trends.

Do I need an Apple Watch?

No. An Apple Watch adds automatic sleep and activity data. Without it, you can log manually or share via Health.

How does the AI meal analysis work?

Take a photo or describe your meal. The AI estimates calories and macros. You can always adjust manually.

Is my data shared?

Your data stays yours. Processing is local or with your consent (e.g., for AI). No selling or third-party sharing.

Is there a free tier?

Yes, core features are free. Premium unlocks advanced insights, weekly reports, and full history.
