About
Built from personal experience.
HushOS is a free, offline-first, patient-built sound app. No ads, no tracking, no account, no Pro tier — by deliberate choice.
Hi, I'm Navdeep.
I built HushOS after struggling with tinnitus, focus and sleep challenges myself.
I found that certain sound combinations personally helped me feel calmer, focus better and sleep more comfortably. After trying many expensive tools and apps, I wanted to create something simple, private and free that others could try too.
I'm not a doctor or clinician — just someone sharing something that personally helped me, and hoping to learn from real people through feedback. If you are an audiologist, ENT, therapist or researcher, your eyes on the wording would lift this meaningfully — please tell me what to change.
Why this exists
Tinnitus affects an estimated one in seven adults in the UK. Around two million live with daily distress from it. The therapies that work — cognitive behavioural therapy, sound enrichment, structured habituation, jaw and neck work where relevant — are unglamorous, daily, and largely unavailable on the NHS within a useful timeframe.
The paid alternatives are expensive. Private programmes run into thousands of pounds. Specialist devices cost more. None of that should be the condition of getting help when the sound is loud at three in the morning.
HushOS bundles every therapy that has independent evidence into one free web app that works offline, asks for nothing, and stays out of the way. If it helps you, we want you to tell one other sufferer it exists.
How to help build it
HushOS is built in the open. There are three ways anyone can make it better, ranked by how useful each one is right now:
- Feedback from anyone using it. If you have tinnitus and you tried HushOS for a few days, tell us what worked and what didn't. One honest sentence helps more than a long theory.
- Specialist review. Audiologists, ENTs, CBT and ACT therapists, somatic physios, researchers — your eyes on the scripts, the protocols, the wording, would lift this app meaningfully. We do not have clinical training; you do.
- Code or content contributions. The source is public on GitHub. PRs welcome — especially translations, better microcopy, accessibility fixes, and bug reports.
We are not asking for money. If you want to donate later, the option is at /support — but right now, feedback matters more.
Inspired by research
The sound tools and exercises in HushOS are adapted from publicly published academic work — notched audio (Okamoto / Pantev, PNAS 2010), acoustic coordinated reset (Tass), structured reflection courses (Andersson / Kaldo / Beukes), somatic protocols (Levine et al.), coherence breathing (McCraty). These are starting points, not promises of outcomes. Experiences vary between individuals.
Private by design
No accounts required. No tracking. No analytics. Every test score, mix, profile and uploaded sound stays in your browser's storage. Optional sign-in (when enabled) only backs that data up across your devices.
Free, forever
No Pro tier, no ads, no upsell. If you can support us at /support, wonderful. If you cannot, use the app and let it work.
By a person, not a clinic
HushOS was built by Navdeep — someone who lives with tinnitus and writes code. Not a doctor, not a clinic, not a medical company. Specialist review and honest user feedback are welcomed openly.
