How’s your hearing? Learn your Hearing Numbers—the softest sound you can hear in each ear—with an app created by the Johns Hopkins Bloomberg School of Public Health. Then use your Hearing Numbers to protect your hearing and hear better. Track your hearing to know how it changes over time and encourage others to know their hearing. Take charge of your hearing wellness! Hearing Numbers can be as low as -10 or as high as 100 decibels, or dB. The higher your Hearing Numbers are, the louder sounds will need to be for you to hear them, and the harder it will be to hear and communicate in noisy places. Requires headphones, a quiet space, and about 5 minutes to complete. No advertising, in-app purchases, or product recommendations. The app tests the noise level around you, measures your hearing levels at four frequencies in each ear, and provides your Hearing Numbers. Share the Hearing Number app and encourage your friends and family to learn their Hearing Numbers. Re-check your Hearing Numbers from time to time and review previous results to track how your hearing changes over time. Learn more about the Hearing Number and how to use it at app.HearingNumber.org. This app is created by the Johns Hopkins Bloomberg School of Public Health, seeking to empower people to know their hearing—millions at a time. Disclaimer This hearing wellness app does not constitute medical advice or diagnosis. You should consult with a health care provider for questions related to your hearing or if you are experiencing any of the following: ear pain or ringing, dizziness, ear drainage or a sense of something in your ear, sudden or fluctuating hearing loss, injury or deformity to your ear, or worse hearing in one ear (i.e., your right and left Hearing Numbers are different by more than 10 dB).

Verdict

The call

The clearest difference is rating: Hearing Number at 4.9 against Insomnia Coach's 3.7. Hearing Number also leads on update cadence (every 3 months vs every 9 months) and ratings volume (599 vs 90). Insomnia Coach's advantage is iOS requirement (13.0 vs 16.4). On price, review sentiment, ads and in-app purchases there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Hearing Number holds the better App Store score, 4.9 against 3.7. That said, the two scores are not equally well evidenced: Hearing Number has 599 ratings behind it against 90, so its average is the more settled of the two. Written reviews complicate that: 50% of Insomnia Coach's written reviews are positive against 43% of Hearing Number's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Insomnia Coach ships an update every 9 months, Hearing Number every 3 months. The most recent releases landed on November 5, 2026 and November 8, 2026 respectively.
