Breathing Exercise

Overview

Breathing Exercise is a calm, guided breathing app. An animated circle grows and shrinks in time with each breath, so you just follow along.

What It Does

• 5 breathing patterns: 4-7-8 for anxiety relief, Box Breathing (4-4-4-4), 2-1-4-1 for a quick calm, 6-2-6-2 for deep relaxation, and 1-0-2-0 for an energy boost
• Animated breathing circle that expands and contracts in sync with each phase
• Colour-coded phases for inhale, hold and exhale
• Phase timer and cycle counter
• Gentle vibration at the end of each cycle

How It's Built

• Custom view draws and animates the breathing circle.
• No internet and no data collection; the only permission is vibration.
