FitBites

A Simple, One-Use App For Effortless Calorie Tracking

1. Overview

FitBites is a free, open-source AI food analyzer and calorie tracker. You type what you ate—like “2 roti and dal”—and the AI instantly estimates calories, protein, carbs, and fat. No barcode scanning, no cluttered menus: it feels like a notes app for food. The product is built for speed and simplicity: Expo powers the Android experience, Next.js delivers the web app, and Appwrite handles auth, data, and sync in the cloud.

2. The Product Pitch

Track calories effortlessly. No bloat, no complex menus—open the app, log meals, and stay in control. FitBites removes the friction of daily tracking so you spend seconds logging, not minutes hunting through databases.

3. Three Steps To A Steady Rhythm

01 — Set Your Goals

Enter age, weight, and goal. The AI calculates personalized daily calorie and macro targets so you are not guessing.

02 — Log With AI

Type naturally: “1 roti” or “100g rice.” The model estimates calories and macros without manual lookup or barcode workflows.

03 — Track Progress

See progress with clean charts: protein, carbs, and fats update in real time so you always know where you stand.

5. Implementation Notes

Backend and product services run on Appwrite for authentication, database, and APIs that keep web and mobile in sync. The mobile client uses Expo for a fast iteration loop and native Android distribution; the marketing and web experience ships on Next.js. Together, the stack keeps hosting costs predictable while staying easy to extend for new AI or analytics features.

6. Summary

FitBites proves that health tooling can stay minimal, fast, and fully open. By pairing natural-language AI with a notes-like log and Appwrite-backed sync, it delivers a modern calorie tracker without the usual app bloat—free for everyone who wants to log food the simple way.
