Confidence & assumptions: how to make photo estimates more accurate

Photo analysis is always an estimate. That’s why we show confidence and assumptions — so you know where uncertainty comes from.

When accuracy drops

• Portion size isn’t clear (plate size, missing context, cropped photo).
• Oil/sauce is unknown (they add a lot of calories).
• Complex dishes (lasagna, ramen, layered bowls).

How to improve accuracy in 5 seconds

1. Tap an option from follow-up buttons (if the bot asks).
2. If the portion looks bigger/smaller — use portion 1.5× / 0.5×.
3. Mark oil/sauce/drink if they were present.

A useful mindset

Don’t chase “perfect”. Aim for good enough: 1–2 quick clarifications usually give you most of the benefit.
