Maazan | GoAI

Maazan (Hebrew for "balance") is a Hebrew-first, fully RTL nutrition tracking app for Android: a daily food diary with calorie and protein targets, quick logging by meal photo, barcode scan, or text search, and a self-correcting target engine that adapts to your real data.

How it works

Four logging paths, one confirmation screen: text search, barcode scanning, AI photo recognition, or saved meals, all converging on a fast, forgiving confirmation screen where quantities and values can be corrected before saving.
A personal catalog that learns: lookups check your own verified catalog first, then Open Food Facts and USDA FoodData Central. Every manual correction is remembered, so accuracy improves with use.
The Israeli-products fallback: when a barcode is found nowhere, you photograph the nutrition label and the app extracts per-100g values, filling the gap that international databases leave for Israeli products.
Adaptive targets: the initial target uses the Mifflin-St Jeor formula; a weekly job then compares predicted vs. actual smoothed weight change, backs out your true energy expenditure, and adjusts the daily target with a short Hebrew explanation and safety guard rails.

What you get

A Today screen showing consumed, target, and remaining calories and protein; a Progress screen with smoothed weight and waist trends, BMI and waist-to-height ratio shown as trends rather than verdicts, and a timeline explaining every target change; saved meals always computed from their ingredients; and Hebrew food suggestions that close your protein gap using foods you actually eat.

Privacy

No account, no email, no login: identity is anonymous per install. Food photos are used only to extract nutrition values and are deleted immediately after analysis. Full data export and deletion are built in. Privacy policy.

Behind the scenes

React Native with Expo and TypeScript; Cloudflare Workers for all server logic including scheduled jobs; Cloudflare D1 as the database and R2 for temporary image storage; Anthropic's Claude API for photo recognition, label OCR, and daily suggestions.

FAQ

Do I need an account?

No. There is no signup, email, or password. Each install gets an anonymous identity, and all data belongs to that install only. The built-in export feature is your backup.

What happens to my food photos?

Photos are resized on-device, sent solely to extract nutrition values, and deleted immediately after the log entry is saved. There is no permanent photo archive.

How does the adaptive calorie target work?

The starting target uses the Mifflin-St Jeor formula. A weekly engine then compares predicted vs. actual smoothed weight change, infers your true energy expenditure, and adjusts the target with guard rails and a plain-Hebrew explanation for every change.

Is there an iOS version?

Maazan currently ships on Android via Google Play. It is built with React Native and Expo, a cross-platform foundation.
