is a professional, coach-style breathing trainer that runs entirely in a compact Chrome popup. It delivers precise, visual and auditory cues for evidence-inspired breathing protocols—Box (4-4-4-4), 4-7-8, and Paced breathing (by BPM)—to help downshift stress quickly and consistently.
Open the popup, pick a protocol, set your session length (1–30 minutes), and press Start. A clean, high-contrast progress ring animates each phase, while the center display shows the current phase (INHALE / HOLD / EXHALE) and live seconds remaining. Real-time KPIs track total breaths, elapsed time, and time remaining. Optional soft beeps and haptics (if supported) provide coach-like cadence without distracting visuals. Prefer a slower, more relaxing pace? Use Paced mode and select a BPM (e.g., 6 breaths/min) to match your target ventilation rhythm. Everything runs locally and offline—no accounts, no internet calls, no data sharing.
Built for focus and reliability:
Coach-grade timing with per-second updates and tabular numerals.
Crystal-clear UI for quick comprehension under stress.
One-click controls (Start, Pause, Reset) and Auto-repeat.
Copy protocol: export a quick session summary for notes, checklists, or sharing.
State persistence: your last protocol, duration, BPM, cues, and toggles are restored automatically.
Track and analyze Chrome Web Store extensions with comprehensive analytics and insights.
