How do I search for a food?
Open Add a meal and choose Find a food. Type a name and the food database lists what matches; pick one and set the amount before you save. Foods you logged recently are kept, so the porridge you have most mornings is a single tap rather than a search.
If nothing in the database is quite right, write the food in yourself. A family recipe, a dish from a stall, a snack with no barcode: your record should hold what you ate, not the nearest thing a database happens to have. Search and writing a food yourself are free and unlimited, for everyone.
