Active Workout	Meal Ideas

Consistency is a browser-based record for food, workouts, recovery, and progress. It keeps entries on the current device and does not require an account.

What it includes

• A food diary for meals, calories, macros, water, weight, and sleep
• A retained catalog of 719 common foods and 52 meal ideas with shopping lists and one-step diary logging
• A searchable library of 400 RepDB exercises with licensed movement illustrations
• Workout sets, editable plans, strength records, cardio sessions, and Garmin activity or sleep imports
• Weight, training, recovery, muscle-group, and weekly views grounded in saved records
• Validated JSON export and restore, including a backup before a local reset
• Light, dark, and device theme choices

The application stays focused on five destinations: Today, Log, Train, Trends, and Settings. Related tools live within those destinations.

Run locally

npm install
npm run dev

The project is configured for the /HealthCore/ GitHub Pages base path.

Verify the project

npm run typecheck
npm test
npm run check:copy
npm run test:e2e
npm run build

The browser suite covers primary destinations and subviews, food, meal, cardio, and workout flows, responsive overflow, and automated accessibility checks.

Architecture

• React 19, TypeScript, Vite, and React Router
• Zustand state with validated local-storage persistence
• Recharts for trend views and Motion for reduced-motion-aware route transitions
• Zod validation for backups and migrated records
• Playwright, axe-core, Vitest, and Testing Library for verification

Large routes load on demand. Exercise data is accessed through a repository interface so its provider can be changed without rewriting the training interface.

Data and privacy

Consistency has no hosted user database or account system. Food, workout, recovery, and profile records remain in the browser unless the person using the app exports a backup. Garmin files are parsed locally.

The Check-in view summarizes saved records deterministically.

Exercise data and attribution

Exercise metadata and movement images are provided by RepDB under its free-tier terms. The included license and attribution files are copied to public/credits and surfaced inside Settings.

Gym Visual media was evaluated but not included because cloning a repository does not grant a separate downstream media license. No generated exercise artwork is used.

Project history

Consistency replaces the original single-file HealthCore application with a typed, tested component architecture while preserving useful product data. The feature-parity record documents the transition, and the original application remains at docs/legacy/healthcore-monolith.html for auditability.

The design research and source decisions are recorded in docs/brain-wiki-source-ledger.md.
