Zementio – Lighter than Cement
Zementio is for anyone who wants to count calories but finds other apps too tedious or cluttered. You take a photo of what you eat, and an AI from OpenAI estimates the calories; if something is unclear, it asks a short question. All entries stay on your device, with no account and no app server. The estimates use your own OpenAI API key.

Zementio is not a medical device. Calorie values and targets are estimates by a formula or an AI, may be wrong and are no substitute for advice from a doctor or nutrition professional. Talk to a doctor before major changes to your diet, especially if you are pregnant, ill or have an eating disorder.
