AYRO: TRAIN YOUR BREATHING. INCREASE YOUR PERFORMANCE. Most breathwork apps give you a library. Ayro gives you a training system: a measurable baseline, a structured block built around your goals, and a retest that shows exactly what changed. Your breathing efficiency is measurable. It's trainable. And a consistent practice reshapes how you perform under pressure, recover from effort, focus through noise, and hold steady under stress. WHAT IMPROVES - Endurance. Be steadier when it's hard. Build tolerance for breathlessness so intense moments feel manageable instead of overwhelming. - Recovery. Become stronger and faster-recovering. Train techniques that support endurance and bring you down faster after effort. - Mind. Stay sharper and more focused. Develop sustained attention that holds through deep work, long days, and high pressure. START WITH YOUR BASELINE The BOLT (Body Oxygen Level Test) is a quick breath-hold measurement that gives Ayro an objective starting point: measured in seconds, not a vibe check. Your score maps to one of six training levels. Most untrained people score 10 to 20 seconds. Elite endurance athletes often exceed 40. YOUR TRAINING BLOCK Instead of scrolling a library wondering what to do next, Ayro builds a structured training plan: matched to your BOLT level and weighted by the outcomes you're actually training for. Complete your block. Retest your BOLT. Your next block meets you at your new level. QUICK TOOLS FOR SPECIFIC MOMENTS - Pre-Workout Activation: prime your system before training - 2-Minute Reset: clear your head mid-day - Focus Primer: sharpen attention before deep work - Post-Workout Downshift: help your body recover faster - Sleep Wind-Down: ease your system into rest BUILT FOR REAL PRACTICE - Breathing ring: immersive visual guides every phase in real time - Phase haptics: feel each breath without looking at your screen - Spoken and audio cues: hands-free guidance - Picture in Picture: breathing ring floats over your screen when you switch apps THE SCIENCE Structured breathing practice improves Heart Rate Variability (HRV), stress recovery, endurance capacity, and sustained attention. The difference between a real training approach and random sessions is progress you can measure. Ayro is built on established techniques: reduced breathing, breath-hold tolerance training, resonance-frequency breathing, and nasal breathing protocols, the same foundations used by elite athletes, coaches, and practitioners worldwide. FOR ANYONE BUILDING A PRACTICE Athletes. Runners. Office workers reclaiming focus. Students under pressure. Anyone who wants a steadier, more capable nervous system. This is breathing as a learnable skill: practiced deliberately, tracked honestly, developed over time. PRIVACY Your health data stays with you.
