MacroDay guide
Find and scan food in MacroDay
Start with a food you already saved, search the catalog, scan a supported barcode, or read a Nutrition Facts label on your iPhone. Whichever route you choose, review the serving and nutrition before saving.
Scan
Use a supported retail barcode or an English Nutrition Facts label.
Review
Confirm the source, serving, and nutrition values before saving.
Search a food or product
- From Today, choose Add Food for the meal you want.
- Select Search or Scan Products.
- Enter at least two characters, then choose Search Catalog.
- Select a result, review its serving and nutrition, choose the meal and number of servings, then tap Save and Log.
MacroDay checks its bundled USDA common-food catalog first. When there is no confident offline match, it may send the search text to Open Food Facts to look for a packaged product. Results identify whether the source is USDA FoodData Central, a saved food, a MacroDay-verified label, or community-supplied Open Food Facts data.
Scan a barcode
- Open Search or Scan Products and choose Scan Barcode.
- Allow camera access if iOS asks, then hold a supported retail barcode in view.
- MacroDay checks foods saved on your iPhone, its verified catalog, and then Open Food Facts when needed.
- Review the returned serving and nutrition before saving and logging it.
MacroDay supports 8- to 14-digit retail barcodes in the formats available to its scanner. If a code is valid but the product is not found, the app offers Nutrition Facts scanning or manual entry.
Scan a Nutrition Facts label
- Choose New Food, then Scan Nutrition Facts Label—or choose that recovery option after a product is not found.
- Fit the full label in the frame, reduce glare, and hold the iPhone still.
- When calories, fat, carbohydrates, and protein are detected, choose Use Scanned Values.
- Enter or review the food name, brand, serving, optional nutrients, and barcode before saving.
Text recognition runs on the device. MacroDay does not retain or transmit camera images. Camera scanning depends on device support and availability; manual entry remains available when it cannot be used.
When accuracy matters
Food databases and label recognition can be incomplete or out of date. Check the current package label, correct the saved food in My Foods when needed, and consult a qualified professional for medical or individualized nutrition advice.
