Are you feeling stressed, burned out, or just not yourself? Optimal HRV is the guided biofeedback app that teaches your body to calm down — for real. Backed by a Harvard Medical School mindfulness expert and trusted by athletes worldwide. Optimal HRV pairs real HRV data with live biofeedback, so every session trains your nervous system to handle stress better — not just tells you that you're stressed. Why HRV and Biofeedback Training Work Your Heart Rate Variability (HRV) is a window into how well your body handles stress, anxiety, and recovery — and biofeedback is how you train it to improve. Together, they show you what's happening inside your body, then guide you to change it in real time. With Optimal HRV, you can: • See how stressed — or relaxed — your body really is, using real HRV data. • Learn what actually helps you recover, from sleep to workouts to busy workdays. • Use live biofeedback to train your body to relax faster, right as it's happening. • Discover your own personal "perfect breathing rhythm" through guided sessions. Features You'll Actually Use • Daily Check-Ins — take a quick reading each morning, or anytime you want to see how you're doing. • Your Perfect Breathing Rhythm — a simple test finds the exact breathing pace that works best for you. • Live Feedback While You Train — a simple on-screen guide shows you when you're doing it just right. • Calming Mindfulness Sessions — guided practices created with a Harvard Medical School mindfulness expert, covering stress, anxiety, pain management, athletic performance, and more, with calming narrations in your choice of voice. • Easy-to-Read Progress — see your trends over days, weeks, and months, no data expertise needed. • Video Tutorials — learn HRV concepts and techniques at your own pace. • Make It Yours — adjust sounds, pacing, and reminders so training fits your life. • Available in 14 Languages — use Optimal HRV in your native language. • Device Testing — quickly verify if your heart rate monitor works with the app. • Great for Teams Too — employers and coaches can track group wellness together (Dashboard access needed). Why Optimal HRV Works with External Sensors (Not Apple Watch) We choose precision over convenience. Apple Watch is great for daily wellness, but Optimal HRV is built for serious HRV training. That's why we connect directly to an HRV monitor via Bluetooth — they deliver millisecond-accurate R‑R intervals that wrist sensors can't match. What that means for you: • More accurate data – better insights, better decisions. • Real-time streaming – no gaps, no guesswork. • Reliable results – trusted by athletes and coaches worldwide.

About

Snore Pro

Features
Read full description

You wake up tired. Your partner says you snore. You have no proof. SNORE fixes that in one night. Leave your phone next to the bed, plugged in, with SNORE running. While you sleep, the app listens ambiently and detects every snore episode using on-device acoustic analysis. No microphone stream ever leaves your phone. In the morning, you open the app and see: • A SNORE SCORE from 0 to 100 — excellent, mild, moderate, high, or severe • A full-night WAVEFORM with color-coded intensity (blue = silent, yellow = mild, red = loud, dark red = severe) • BREATHING STABILITY analysis — flags suspicious pauses between loud episodes (useful context to discuss with your doctor; not a medical diagnosis) • PLAYBACK with pinch-to-zoom so you can hear the exact peaks • HISTORY with streak counter, average score, and trend chart • LIVE ACTIVITY on Dynamic Island showing the recording is active without waking the screen Why SNORE exists: Other snore apps charge $9.99/month, demand an account, and upload your audio to their servers. That is wrong. Your breathing while you sleep is the most private data you produce. SNORE was built by a solo developer who believes health data belongs to you. It has: • ZERO backend. Zero servers. Zero cloud. • NO account. No email. No login. • NO ads. No tracking. No analytics. • NO hidden subscription. The core app is free forever. Everything runs locally using Apple Sound Classification and SwiftData. Your audio files stay on your device and you can delete them with one tap. FEATURES • All-night ambient snore detection • ML-validated episodes (filters out fan noise, traffic, white noise) • Ambient noise auto-calibration • Charger reminder before sleep • SNORE Score 0–100 with clinical-style labels • Color-coded waveform (blue / yellow / red / dark red) • Breathing stability indicator • Tap-to-play any peak in the waveform • Pinch-to-zoom playback • Streak counter and 7/30-day averages • Daily bedtime reminder (optional) • Dynamic Island Live Activity during recording • Home screen widget with last night's score • Trilingual: English, Español, Português (Brasil) • Privacy Manifest compliant • Works offline. Always. REQUIREMENTS • iPhone with iOS 17 or later • Microphone permission (local only) • Plug the charger in before sleep — recording all night drains the battery DISCLAIMER SNORE is a consumer wellness app. It is not a medical device and does not diagnose sleep apnea, UARS, or any condition. If you or your partner notice loud snoring, gasping, or witnessed pauses, consult a sleep specialist. MEDICAL REFERENCES Includes verified medical references. Severity thresholds, breathing pattern analysis and wellness recommendations are cited to internationally recognized sources: NIH, Mayo Clinic, AASM, CDC, Harvard Medical School, Sleep Foundation and WHO. Access the full list from Settings → Medical Sources, Settings → FAQs, or the "Sources" button shown next to your nightly score. Sleep better. Know the truth.
