Features & Capabilities

Track your breathing overnight with on-device AI. Three independent classifiers analyze every breath while you sleep. No audio uploaded, ever.

You breathe 20,000 times a day. Most of them through your mouth, without even knowing it.

Mouth breathing leads to poor sleep, low energy, dry mouth, and anxiety. Nostril helps you switch to nasal breathing with daily tests, guided exercises, and overnight sleep tracking so you can feel the difference in days, not months.

MEASURE YOUR BREATHING FITNESS Take the Control Pause test to measure your body's CO₂ tolerance, the most reliable marker of how well you breathe. Track your score over time and watch it climb as your habits improve.

TRACK YOUR SLEEP (Premium) Place your phone on the nightstand and let Nostril listen overnight. Wake up to a clear breakdown of nasal vs. mouth breathing, snoring episodes, and trends across nights. All audio is processed entirely on your device. Nothing is ever recorded, stored, or uploaded.

RESET IN 60 SECONDS Feeling stressed? The guided Reset session walks you through 60 seconds of slow nasal breathing with gentle haptics and visual cues. Inhale 4 seconds, exhale 6. Log your mood after each session to see the pattern.

SEE YOUR PROGRESS (Premium) Charts, streaks, and a year-long heatmap show how far you've come. Dive into detailed sleep analytics, weekly compliance scores, and Control Pause trends, all in one place.

BUILD THE HABIT Set daily check-in reminders that ask one simple question: are you breathing through your nose right now? Over time, awareness becomes automatic.

PERSONALIZED FROM DAY ONE A quick assessment during setup analyzes your breathing patterns, sleep quality, and symptoms to give you a personal breathing score and focus areas tailored to you.

PRIVACY FIRST Sleep tracking uses on-device audio analysis with multiple AI layers. No audio is saved. No data leaves your phone. Ever.
