Guided tongue and throat exercises. Animated, voice-cued, no equipment needed. Like physiotherapy, but for the muscles that keep your airway open.
The Cochrane Review (2020) found these exercises reduce AHI by an average of 13 events per hour.⁴03 · PROVE

StopSnor is a wellness product. It is not a medical device and does not diagnose or treat sleep apnea. If you experience choking, gasping, or severe daytime sleepiness, please consult a physician.
Why not just a CPAP, mouthguard, or sleep clinic?
Each option has a place. Here's where StopSnor fits — and where it doesn't.

The 12-week journey.
Week 1
Baseline
Establish your snoring fingerprint and resting heart rate.
Weeks 2–4
Learning
Master the seven foundational exercises.
Weeks 5–8
Consolidation
Snore intensity typically drops 30–40%.⁵
Weeks 9–12
Mastery
Meaningful reductions in AHI risk score. More quiet nights, on the record.
What 12 weeks looks like in published studies.
Two independent studies tracked the same outcome — apnea-hypopnea index (AHI) — over 12 weeks of myofunctional therapy. Here's what they measured.

Why we're building StopSnor
"We started StopSnor because we lived this. Years of sleepless nights — ours, our partners'. The exhaustion. The separate rooms. The fear that something might be seriously wrong. We tried everything: strips, mouthguards, apps that just recorded the noise but never helped fix it. So we built what we wished existed — backed by the science, made for both people in the bed."
From the research
"Myofunctional therapy decreases the apnea-hypopnea index by approximately 50% in adults and 62% in children."— Camacho et al., Sleep, 2015 (meta-analysis)
"After 90 sessions of smartphone-guided exercises, snoring decreased by 53% in patients with severe OSA."— O'Connor-Reina et al., JMIR mHealth, 2020

Frequently asked.
When will the app launch?
We're targeting public launch in the coming months. Founding members on the list get the launch email first — with their 50% off code already attached.
I've tried other snoring apps and they didn't help. What's different here?
Most snoring apps just record. They tell you that you snore — which you already knew. StopSnor is the first that does all three: detects the snoring, gives you daily exercises that actually train the airway muscles (Cochrane 2020 confirmed AHI reduction of 13 events/hour with this approach), and uses your wearable to prove it's working through real heart-rate data. No more "you snored 247 times last night" with no path forward.
Do I pay anything now?
No. You only pay if you choose to subscribe at launch — and only at the discounted founding-member price. The signup is just to reserve your spot and your discount code.
How does the 50% discount work?
Sign up with your email today. When we launch, we send you a link with a personal code that drops the price from $119 to $59 for your first year.
My partner is the snorer — how do I get them to actually use this?
You're not alone — about a third of our early signups come from partners, not snorers. The thing that works: it's not nagging. The before/after data feels different from "you snored again last night" because it's their data, their trajectory, and their improvement to be proud of. Many users tell us the partner sets it up the first night, and after a week the snorer keeps it going themselves because the streak feels good. We'll be writing more about this approach in our pre-launch emails.
What if I change my mind?
No risk. Don't subscribe at launch and you've lost nothing. Or subscribe and use the 30-day money-back guarantee — full refund, no exit survey, no questions.
Will it work on Android, or only iPhone?
Both. StopSnor launches on iOS and Android simultaneously. The wearable integrations supported on each platform are identical: Apple Watch, Garmin, Fitbit, Oura, Samsung, WHOOP, Withings, and Polar.
Does it work without a smartwatch?
Yes. The core monitoring (audio-based snore detection) and the daily exercise program work with just your phone. A wearable adds heart-rate and HRV signals — useful, but not required.
Is my audio data private?
Yes. 100% on-device processing. Audio is analyzed on your phone and never uploaded to a server. Only summary metrics are saved.
Will this replace my CPAP or sleep doctor?
No — and we'd never claim otherwise. StopSnor complements medical care, never replaces it. If you have diagnosed sleep apnea, keep your CPAP and your doctor.
Will this work for severe snoring or sleep apnea?
The strongest evidence is for primary snoring and mild-to-moderate OSA. Smartphone-delivered exercise programs have shown meaningful reductions even in severe cases (53% in O'Connor-Reina 2020), but severe OSA always warrants a physician's care first.
