AI nutrition tracking without turning dinner into a math problem.

Most macro trackers either turn nutrition into a math problem (weigh, scan, compute) or smooth it out so much that the data is useless. Casey does neither. You describe a meal the way you’d describe it to a friend; she estimates, errs slightly conservative, and surfaces patterns when they matter.

“Patterns over individual meals” is the literal Casey quote. A bad day doesn’t do anything. A bad week starts a conversation. A bad month gets a specific recommendation: protein’s low on lifting days, carbs are crashed on Thursdays, dinner timing is moving later and weight isn’t responding the way it was.

Daily kcal target, protein floor, and macro splits are configurable from your goals. Casey won’t moralize. She’ll meet you where you are and tell you what to do next.

Beyond calories and macros, the meals you log get a nutrient panel with targets, history and top contributors. See micronutrient tracking.

Your kcal target starts from a maintenance estimate, and maintenance calories are a range, not a magic number, so Casey treats the starting point as a hypothesis to correct against your actual trend, not a fixed answer.
