A few real questions. Nobody gets turned away for these. They decide which of two modes you start in: the full counting version, or Kitchen mode — same coach, same photos, no calories, no weights, no scores. Just what's in your fridge and what to do with it. You can switch either way any time.

These next two don't stop anything. They change how it coaches you.

4 slices turkey, 4 ham, 2 tortillas, some cheese
Logged. 540 kcal · 52 g protein That's your whole per-meal number in one plate. Heads up though: cheese is 5.8 g per 100 kcal. It's a fat that happens to carry protein. The turkey's doing the actual work at 20.
scale says 198.8, down 2 👀
Careful, that's one morning. Your ten-day trend is 201.7, falling about 0.3 lb/wk. Monday you were 205.3, so most of that 2 lb is just water leaving after the weekend. Nothing to do differently. Weigh again tomorrow.

It only really teaches one number.

Grams of protein per 100 calories. It turns "eat less" into "swap that for this", which is a question you can answer standing in your own fridge at 10pm.

Photograph the block of cheese before and after and it works out exactly what left the plate. Same with a shared board, a takeaway container, or a pan of something.
