The short answer

The Her Good Days food diary has a free food scanner. Scan the barcode on a packet and the food is added with its calories, protein, carbs, fat and fiber.

You set the amount you ate before you save, and you can add a photo of your meal, which stays on your phone. The camera is used only when you tap Scan or Photo, and you can always type a food in by name instead.

How do I scan a barcode?

Step 1

Tap + Log, Meal, Scan

The camera opens with a frame. The first time, your phone asks if the app may use it.

Step 2

Set the amount

The values are for one serving as printed. Change the servings to what you ate, then add it to the meal.

Step 3

Save it

It lands in the meal and on Today, and goes into your saved foods, so next time it is one tap from the list.

What about a meal with no barcode?

Search for each food by name and pick the amount, then save it as one meal. Tap Photo to keep a picture of the plate with it, on your phone only.

Meals you eat often can be saved too, so Monday's lunch is a tap on Tuesday.

Search, Scan and Photo on the Log a meal screen.

Questions

Is the food scanner free?

Yes. The barcode scanner and meal photos are part of the free food diary. There is no premium tier.

What happens to a meal photo?

It is saved with that meal, on your phone, so you can see later what you ate. The numbers come from the foods you add, by barcode or by search.

Does the app keep my camera on?

No. It asks for the camera the first time you tap Scan or Photo, and uses it only then. You can turn it off in your phone's settings and still type foods in.

Can I set my own portion?

Yes. After a scan, change the amount to what you ate. A packet's portion is the maker's idea of one, and it may not match yours.
