Help us build a hearing app you'd actually use.

We are looking for 75 people to put iHEARtest, our free at-home hearing screening, through real-world use before we launch on the App Store. Your honest reactions help us ship something genuinely useful instead of just shippable.

Apply for the beta  → 75 spots. Beta launches Monday, June 1, 2026.

What is iHEARtest?

iHEARtest is a free iPhone app from OTCHealth that gives you a clinical-quality hearing screening at home in about five minutes. You put on headphones, sit in a quiet room, and tap a button each time you hear a tone. Same protocol an audiologist uses, just on your couch. At the end you get your Hearing Number (0 to 100, lower is better, like a golf score), a standard audiogram you can email to your doctor, and a plain-English explanation of what your result means and what to do next.

Who's behind iHEARtest

iHEARtest is the result of a partnership between InnerScope Hearing Technologies, a publicly-known builder of hearing-health software and consumer hearing solutions, and OTCHealth, an over-the-counter hearing device retailer at otchealthmart.com. InnerScope leads the engineering and product design. OTCHealth provides clinical input, the audiologist network, and the device catalog the app's recommendations connect to.

The same team that designs our devices designs the app, alongside licensed audiologists who sign off on the test protocol.

iHEARtest is a hearing screening tool, not a diagnostic medical device. It does not diagnose, treat, or cure any medical condition. Results do not replace a clinical evaluation by a licensed audiologist. For diagnosis or treatment of hearing loss, please consult a qualified hearing-health professional. Intended for adults 18 and older.

FAQ

When will I hear back, and what if I am not picked?
On Monday June 1st every applicant gets either an acceptance email or a waitlist email. Accepted testers then get a separate Apple TestFlight invite to accept within 24 hours. If you are on the waitlist, you are first in line when the next round opens.
How long will the beta last?
About 6 to 8 weeks. You can leave any time. We'll ship 2 to 3 new builds during that window; each one is a one-tap install via TestFlight.
Do I need to be over 50?
No, anyone 18 or older with an iPhone can apply. We do especially want testers who are 50 or older since that's the demographic the app is designed for, but younger testers help us catch issues older testers might not flag.
Is this an iOS-only beta?
Yes. Apple's TestFlight is iPhone and iPad only. Android beta opens late 2026. Leave your email if you want to be notified.
Will the app drain my battery or use up my data?
No. The hearing test runs locally on your phone (no server calls during the test). The app uses cellular or wifi only to load articles and send error reports, both of which are kilobytes-level.
What if my iPhone is too old?
iPhone 11 (2019) or newer is recommended; iOS 16.0 or higher is required. Older iPhones may technically work but we can't troubleshoot them during beta.
Do I need special headphones?
No, any headphones work, including wired EarPods or AirPods of any generation. The app has per-headphone calibration profiles for the most common models and falls back to a generic profile for others. The test result is more accurate with calibrated headphones; the app tells you the limitation if your model isn't on the list.
What happens to my data?
Test results, thresholds, and questionnaire answers stay on your iPhone. They are not uploaded to our servers. When the app crashes or hits an error, we send a stack trace to Sentry (our error tracker) with personal data redacted. We do not sell or share your data with hearing-aid manufacturers, insurance companies, or anyone else.
Can I delete my data?
Yes. Settings › Clear test history wipes everything. Uninstalling the app removes everything too.
Is this a real medical test?
It's a screening, not a diagnostic test. The protocol is the same one audiologists use, but a real diagnostic audiogram requires a sound-treated booth and calibrated lab-grade equipment. iHEARtest is designed to tell you whether you should go see one of those. Not replace it.
How accurate is it?
For most people in a quiet room with decent headphones, the Hearing Number is within plus or minus 5 dB of what an audiologist would measure on the same day. That's enough accuracy to spot meaningful hearing change but not enough to fit hearing aids. That requires a clinic visit.
Will I get a paper certificate I can show my doctor?
You can export a one-page PDF (Hearing Number, audiogram, thresholds, date) and email it to your doctor. Many doctors will accept it as a starting point.
What's the $50 credit for?
If your test shows normal hearing, the app generates a one-time $50 credit code you can share with a family member who needs an OTC hearing device from otchealthmart.com. You can't redeem it on yourself; the idea is to make hearing care easier for the person in your life who actually needs it.
What's "free for life"?
Every feature in iHEARtest is free today, and will stay free at the App Store launch. But we're building a paid tier later: Sharpen Your Hearing, a 4-week auditory-training program. That'll be a subscription when it ships in late 2026. Beta testers who participate in this beta get Sharpen Your Hearing free for life, plus any other paid feature we add later.
Who's behind iHEARtest?
OTCHealth, an InnerScope Hearing Technologies company. We make over-the-counter hearing devices that you can buy on otchealthmart.com. The app is how we pay for the app to be free, by surfacing devices to people who actually need them, after we've helped them screen.
How do I leave the beta?
Open TestFlight, tap iHEARtest, then "Stop Testing". Done. No emails, no exit interview, no guilt trip.
