A target that fits the person
The daily calorie target is calculated from height, weight, age, sex and activity level, and recalculates as weight changes.

Vive Move
Indian calorie & macro tracker
A calorie, nutrition and fitness tracker built around how India actually eats. Vive Move turns what you eat and what you move into one honest number, and shows whether it is going the way you want.
Naptrix Labs designed, engineered, and operates every layer of the product—from the Flutter app and its Apple Health integration to the authentication gateway, nutrition database, React admin portal, and public marketing site.

ZeroAds or Analytics Trackers
Ten screens. One honest number.
Every screen is captured directly from the live App Store release—not mock-ups, not rendered comps. Real software, real users.
Your whole day, at a glance
Calories needed, eaten and burned, with macros and goal progress on one screen.
A plan that adapts as you lose
A week-by-week path to the target weight, with a projected finish date that moves as you log.

Meals, workouts and weigh-ins on a single daily timeline.
900+ Indian foods, already counted
Idli, dal, roti and poha with calories and macros per serving.
Macros the moment you add food
Protein, carbs and fat update live as the meal is built.
See your week, not just today
Energy in versus energy out across the week and month.
Every step counts toward your burn
Steps and active energy from Apple Health feed the daily burn.
Log anything in two taps
One button for meals, workouts and weigh-ins.
Your steps, day by day
Daily step history synced from Apple Health.
Walks and runs, mapped live
GPS tracking with pace, distance and the route drawn on a map.
What Vive Move does
A focused calorie, nutrition, and fitness tracker built specifically around how India eats and exercises. No guess-work, no cluttered UX.
Built for Indian food
A curated catalogue of 900+ Indian dishes with calories, protein, carbs and fat per serving. No guessing from foreign databases.
GPS workouts
Walks, runs, rides and hikes tracked live with distance, pace and calories, and the route drawn on a map afterwards.
Apple Health sync
Steps, active energy, sleep and workouts imported from Apple Health, de-duplicated so nothing is ever counted twice.
Insights that mean something
Weekly and monthly views of intake against burn, pace against plan, and logging consistency.
Private by design
No ads, no trackers and no analytics SDKs. Users can delete their account and all of its data from inside the app.
One product. Seven engineering layers.
Seven separately versioned codebases—each designed, built, tested, and deployed by Naptrix Labs. This is the same end-to-end delivery we offer every client.
Mobile App (Flutter)
API & Auth Gateway (Node.js)
Nutrition Microservice
PostgreSQL Databases
Mobile app
A Flutter app for iOS and Android: onboarding, food logging, goals, GPS tracking, Apple Health and Health Connect sync, reminders, light and dark themes.
158 source files · ~33k lines
API & auth gateway
The single entry point for the app. Firebase verifies identity once; the API then issues its own short-lived tokens with rotating refresh tokens, role-based access and audit logs.
18 route groups · 42 test suites
Food service
A separate resource server for nutrition search, the food diary and custom foods. It trusts only tokens minted by the gateway.
Independent service · own test suite
Databases & food data
Two PostgreSQL databases: one for users, roles, sessions, goals and logs; one for the nutrition catalogue, seeded from a curated Indian food dataset.
28 migrations · 1,000+ food records
Admin portal
An operations console for users, analytics, nutrition sources and food records, content pages, push notifications, health-sync monitoring and support tickets.
18 console screens
Public website
The product site with the nutrition-data explainer, support centre, privacy policy and terms. Served without any tracking.
Marketing, support & legal
Cloud & delivery
Separate production and development environments with continuous deployment from GitHub, plus App Store builds, screenshots and the app preview video.
Prod + dev · branch-mapped deploys
Engineering decisions we owned
The architectural choices that separate a production system from a prototype.
Authentication we control end to end
Firebase confirms a Google, Apple, or phone sign-in exactly once. From that point our API issues 15-minute JWT access tokens and opaque refresh tokens stored only as hashed values in PostgreSQL, rotated on every use. A replayed token revokes all sessions for that user instantly.
De-duplicated Health data at the source
Apple Health imports are de-duplicated by source record identifier and by time overlap, so a GPS run tracked natively in the app is never double-counted when Health syncs the same activity.
Security by architecture, not afterthought
IP-level rate limiting, database-backed per-account lockouts, validated and sanitized input on every endpoint, parameterised SQL throughout, and no third-party analytics SDK anywhere in the product. Private by design.
