FAQs

How should I take photos for best accuracy?

Use good lighting, capture the full plate from above, include a size cue (fork/hand), and keep ingredients visible. Edit portions as needed.

Can I still edit meals after scanning?

Yes—adjust portions, add sides/sauces, or leave notes so your macro totals reflect what you ate.

What if I prefer deeper nutrition analytics?

Pair photo logging with periodic manual checks or consider hybrid use of a legacy counter if you need micronutrients and long-form reports.
