Train

Choose from Training sessions (1 Min to 10 Min, Beginner to Expert) or structured Lung Tests that measure your Capacity, Power, Flow, and Rhythm. Each test is timed, guided, and logged automatically.

Measure

Tap and hold the blob to time your breath hold. The result card shows your exact time, your level — Beginner, Intermediate, Advanced, Expert, or Elite — and your progress toward the next tier.

Meditate

Set your breathing pace anywhere from 3 to 12 breaths per minute and let the blob guide you. Tap play and breathe — the app handles the rest. Perfect for daily stress control, HRV improvement, or pre-sleep wind-down.
