You're hungry, so you grab crackers. Or cereal. Or whatever's open. Tell Pearful what you're eating and it suggests a few things to add, so a snack turns into something that actually keeps you full.
Pearful never tells you to remove something, swap it for a "better" version, or eat less of it. It starts from what you already chose and builds on it with protein, fiber and healthy fat, the combination that actually keeps hunger away.
Every feature exists to shorten the gap between "I'm starving" and eating something that holds you.
