Init Review System adds a clean and customizable 5-star rating system to your WordPress site. Votes are stored via REST API, tracked with <code>localStorage</code>, and the average score is auto-calculated and optionally displayed with schema markup.
Built to be lightweight, developer-friendly, and easy to integrate into any theme or custom UI. Now with multi-criteria reviews and an emoji reactions system for richer user interaction.
