Diet App

A daily diet companion that learns from your habits and suggests improvements without the friction.

Project Overview

Nutrition-First Fitness Assistant with Meal Planning, Daily Progress & Intelligence

Metaviz AI built DietApp — a next-generation nutrition and calorie intelligence platform inspired by YAZIO. DietApp allows users to log meals instantly (barcode, search, or photo), follow personalized meal plans, track macros, schedule fasting, sync wearables, and visualize progress through smart nutrition analytics.

This project shows how AI + nutrition science can merge into one flexible app experience. Metaviz AI shaped a complete ecosystem that blends user habits, biometrics, diet patterns, and calorie math — into one adaptive flow that evolves with user progress.

Our Process

From Concept to Adaptive Nutrition Engine

DietApp was built around one truth: nutrition data is useless if it isn't easy to log. Our process focused on removing friction at every step of the user's daily diet flow.

01
Step 1

Consultation & Requirement Discovery

We identified core user needs — instant meal logging, personalized calorie targets, fasting flexibility, and macro visibility.

02
Step 2

Design & Development

We designed a quick-log diary, barcode scanner, and recipe-based meal planner that adapts to user goals and preferences.

03
Step 3

Fasting & Wearable Sync

Metaviz AI implemented fasting timers, hydration reminders, and wearable integrations for automated calorie recalculation.

04
Step 4

Testing & Optimization

Stress testing ensured high performance — especially in food DB search, barcode scanner accuracy, and progress chart rendering.

05
Step 5

Deployment & Premium Models

We implemented in-app subscriptions with secure payments and launched stable builds on iOS + Android.

Nutrition Data Is Useless If It Isn't Easy To Log
The Challenges

Nutrition Data Is Useless If It Isn't Easy To Log

Most calorie apps fail because logging takes too much time. Diet habits are fragile — friction kills consistency.

Existing tools were fragmented: fasting in one app, macros in another, recipes somewhere else, wearable sync in a separate ecosystem. Users needed everything in one place — fast, visual, personalized.

The Solution

A Complete Diet + Progress Engine In A Single App

DietApp consolidates fasting, macros, recipes, and wearable sync into a single Flutter / React Native app — every feature designed to remove friction from daily logging.

01

Ultra-Fast Food Logging

Barcode scanner, search, or optional photo capture — log meals in seconds, not minutes.

02

Personalized Meal Plans

AI-curated meal plans and recipes tailored to dietary preferences, allergies, and calorie targets.

03

Fasting Modes

Built-in fasting timers and reminders — 16:8, OMAD, custom windows — all tracked in one place.

04

Progress Analytics

Weight, macros, and nutrient trends visualized in clean, motivating charts.

05

Wearable Sync

HealthKit, Google Fit, Fitbit, and Withings integration — auto calorie adjustment based on activity.
