RESPIRO - Stress Relief

v2.2.0: Stress episodes, 6 stress levels, smarter check-ins. See when stress peaks — and when it clears.

Your phone already knows when you're stressed. Respiro reads the signals.

Most breathing apps wait for you to open them. Respiro detects stress in the background and sends the right practice at the right moment.

STRESS RADAR — BEHAVIORAL INTELLIGENCE

Respiro monitors 29 signals from 8 sources on your iPhone:

• Sleep patterns and disruptions
• Physical activity and step count changes
• Daily rhythm and routine shifts
• Calendar overload and back-to-back meetings
• Screen time spikes and behavioral changes
• Social media doom-scrolling patterns
• Late-night phone use (strongest stress predictor)
• Evening escapism and compulsive checking
• Weather and barometric pressure
• Your mood feedback loop

No Apple Watch required. Just the iPhone you already carry.

NEW: DIGITAL BEHAVIOR INTELLIGENCE

Respiro is the first breathing app to detect stress from your phone behavior. Screen Time API monitors general usage categories — never specific apps, never content. All on-device.

After a 2-week personal baseline, Respiro learns YOUR normal. When behavior deviates — more screen time, more social media, later nights — it suggests a practice.

Nighttime phone use has an effect size of d=0.8-1.2 on stress. Over 80 daily unlocks correlates with 2.3x higher anxiety.

CALM DOWN IN 30 SECONDS

Physiological Sigh — the technique Stanford researchers found reduces stress faster than any other breathing pattern. Two inhales, one long exhale. Done.

26 SCIENCE-BACKED TECHNIQUES

Breathing, body, and mind practices from 30 seconds to 20 minutes:

• Physiological Sigh (Stanford) — fastest stress reset
• Box Breathing (Navy SEALs) — focus under pressure
• 4-7-8 Breathing — fall asleep naturally
• Progressive Muscle Relaxation — release physical tension
• Grounding 5-4-3-2-1 — stop anxiety spirals
• Body Scan, Butterfly Hug, Cognitive Defusion, and more

Every technique backed by peer-reviewed research. No fluff. No celebrity narration. No sleep stories.

LEARNS WHAT WORKS FOR YOU

After each practice, one tap — "Much better", "A bit better", "About the same", or "Not great". Over time, recommendations get smarter. The app tracks which techniques actually reduce YOUR stress.

Your stress score adapts to YOUR personal baseline. After 7 readings, Respiro learns your normal — "elevated" is calibrated to you, not population averages.
