You get free AI analyses (photo or voice), up to 10 per device per day. Photo and voice share this allowance. Food database search and barcode scanning do not use it.

Both. Plates shows calories, protein, carbs and fat for every meal and for your day. Goals are optional; if you set a protein goal, Plates also shows your protein against it.

Yes, for body weight. If you turn it on, Plates can read and write your body weight with Apple Health.

The app interface is in English. Plates is available for iOS.

Your food logs are stored in the cloud, tied to your Plates account (anonymous unless you link an email, Apple or Google account), and handled under our Privacy Policy. In version 2.5.0 and later, Plates asks your permission before it first sends a meal photo or voice recording (and any note you add) to AI service providers — OpenRouter, Google, OpenAI or Microsoft Azure, and DeepInfra — to estimate nutrients, and asks separately before food search sends your search text to DeepInfra. Manual entry, saved foods and barcode logging work without either permission. To delete your account, see How do I delete my account? below.

Changes you make to a saved meal, such as a new amount, are saved when you tap Confirm. If you leave without confirming, Plates asks whether to discard the changes.

Home now shows today's calories, protein, carbs and fat first, with your meals below. The daily appetite check-in, the protein-gap suggestions and the Week 1 card on Home, and the Appetite profile and Food preferences sections in You, are no longer shown, and goal setup no longer asks what has changed your appetite. Your saved goals and settings are kept.

Plates now asks before sending meal photos or voice recordings for AI analysis, and asks separately before food search sends your search text.

Because the photo or recording is sent to other companies' AI services. In version 2.5.0 and later, before a meal photo or voice recording is first sent, a screen titled “Before we analyze your meal” names the providers and asks for your permission: meal photos go to OpenRouter and Google; voice recordings go to DeepInfra, and the transcript and any note you add are processed through OpenRouter by OpenAI or Microsoft Azure.

Nothing is sent until you tap Allow photo & voice analysis. If you tap Not now, you can still log meals by manual entry, saved foods or barcode. Your answer is saved for your account on that device, so Plates asks again if you sign in with a different account, reinstall the app or use another device.

Food search sends the text you type to DeepInfra to match it with foods. In version 2.5.0 and later, the first time you tap a food search box, Plates asks before sending anything (Allow food search or Not now).

This is separate from photo and voice analysis, so you can allow one and not the other. Without it, you can still add foods by manual entry, saved foods or barcode.

Go to You > Settings, and in the App section tap AI photo & voice analysis or Food search, then tap Turn off.

Turning a permission off stops future sending. It does not delete your saved meals, and it does not recall anything already sent. Plates asks again the next time you use that feature.

In the app, go to You > Settings > Delete account. In version 2.5.0 and later, this deletes your account and the data stored with it on our servers, including your meal records and photos. If you signed in with Apple, it also revokes the Sign in with Apple authorization that Plates holds.

Deleting your account does not cancel Plates Plus; cancel the subscription in your Apple ID settings first. If you deleted your account with version 2.4.3 or earlier, some data such as meal records and photos may remain on our servers. Email info@openhealth.co.jp and we will delete it. Details are in our Privacy Policy.

Open the Trends tab and tap Export report under Protein floor report (PDF), then choose 4, 8 or 12 weeks. The report needs a protein goal; if you haven't set one, Plates offers to set it first.

Plus is optional. It doesn't change meal logging, your daily totals or the daily AI allowance.
