Calorie tracking on iPhone Duo

What changes when you open iPhone Duo?

Your journal expands into two usable columns. In Today, the date, energy summary and water stay on the left, while your meals and the next logging action appear on the right. Each side scrolls independently, so you can check your day's progress while looking through the meal list.

The layout follows the center fold. App controls sit to either side, and the navigation rail occupies the status column on the right edge. The same rail is available on the Duo's outer screen. On other iPhones, navigation remains along the bottom.

How does reviewing a meal work side by side?

The photo and nutrition totals stay on the left, while the ingredients and actions appear on the right. Review the foods the estimate identified, check each portion, and use Correct it in words when you know something the first estimate missed. Logging remains a deliberate final action after you review the result.

For example, if a meal contains less rice than the draft assumes, explain that in the correction field. Review the revised ingredients and total, then log the meal. Watch the correction workflow for a separate demonstration with sample data.

What happens when you open Add food?

Add food opens beside the journal on the open Duo. You can choose a photo, a description, a barcode or another entry method while retaining the context of your day. App editors use that side panel too, including the ingredient editor and daily-goal controls.

System screens such as Apple's photo picker and share sheet follow iOS's own presentation. The camera and barcode scanner use their capture layouts. The purpose of the split is to make reviewing and entering food easier on the open display, while keeping the actions familiar.

What happens when you fold the phone?

SeeMeEat keeps your selected tab and screen and returns to the narrower layout. Today, Trends, Memory, Together and You remain the same destinations. The outer screen shows content in one column, and opening the phone returns to the wider arrangement.

Finish or save an edit before changing posture. Moving between the narrow and wide layouts can restart a list's scroll position or rebuild an open editor. Your saved journal entries remain available.

Is the Duo update available now?

Yes. The core Duo layouts shipped with iPhone version 3.1.0. The selected tab's filled background was released in iPhone version 3.1.2.

The recording retains its 3.1.2 development preview label because it was captured from a simulator development build before release. It is not a recording of the released App Store binary.

The video uses demonstration meals and deterministic sample estimates. It shows recordings of the real app interface in the open iPhone Duo simulator, followed by a labeled still image of Trends on the folded screen. It does not demonstrate a folding transition. Nutrition numbers in the demonstration are examples, not a measurement of analysis accuracy.
