## Description

30 Day Plank Challenge is a lightweight Chrome extension that helps you complete a 30-day plank routine. It counts your plank time once per day, tracks achievement days, and sends friendly reminders to keep you on track.

The extension supports optional health data integration (Apple Health) to record active energy and workouts, provides a simple METs-based calorie estimate, and offers a proximity sensor option for responsive prompts on compatible devices (not on Dynamic Island). It asks for permissions for Apple Health, tracking, and notifications, and is available in Japanese and English.
