How good are the estimates?

A picture of a plate doesn't show the butter in the pan, the oil in the dressing or what's inside a wrap. Portion size is hard to judge from a flat image. Even a person looking at the same photo would be guessing, and so is the AI. It's good at recognising food and working out roughly what's in it. It isn't a food scale.

Each estimate comes with a confidence label: high, medium or low. A tidy plate of recognisable food is high. A bowl of something mixed, in poor light, is not. When it's unsure about something that matters, it can ask you instead of guessing. A drink you log by volume is not an estimate at all: the number is yours. If you know better, say so in a sentence ("no rice") and it adjusts.

Any one estimate can be a bit off, which is why SelfCtrl is built around the week rather than the plate. The pattern across seven days is what's worth looking at, not the exact figure on a single lunch.

SelfCtrl is not a medical device. It doesn't diagnose, treat or prevent any condition, and it isn't dietary or medical advice. If you have a health condition, or you're changing your diet for a medical reason, talk to a doctor or a registered dietitian, who can do what an app can't. It's made for adults.

Food logging isn't right for everyone. If it ever starts to feel stressful, or you have, or are recovering from, an eating disorder, please talk to a doctor or an eating disorder service before using a food tracker, and stop whenever you want. You can export or delete everything at any time.
