mail@23.worksWe read every message and usually reply within a couple of days. It helps to mention your iPhone model and iOS version.
Yes — completely. Every sound and visual lives on your device. No internet, no streaming, no account. Hush works the same on a plane or off-grid as it does at home.
Yes. You buy Hush once and it's yours — no subscription, no in-app purchases, no ads.
On the Mix tab you can layer up to three sounds at once and set each one's volume independently. Save a blend you like from the Mix tab and find it again under "your hush".
Set 15, 30, 60 or 90 minutes, or leave it running. When the timer ends, Hush fades out gently over about ten seconds rather than cutting off, so it never wakes you.
The wake alarm requires iOS 26 or later (it uses Apple's AlarmKit so it can sound even in Silent mode or Focus). On earlier iOS versions the feature is hidden. Make sure you've allowed the alarm permission when prompted.
Sync lets two nearby devices play the same sounds at once over a private local connection — no account or internet needed. Both devices need to be on the same local network with Bluetooth/Wi-Fi enabled.
Hush is designed to keep playing in the background. If it stops, check that Hush isn't being suppressed by Low Power Mode restrictions, and that you didn't unplug headphones (Hush pauses politely when headphones are removed).
Purchases are handled by Apple, so refunds go through Apple rather than us. You can request one at reportaproblem.apple.com.
Hush collects no personal data. See our privacy policy for the details.
