Let’s get you
back to talking.

The phones cannot find each other.

1. Check that both phones use the same Wi‑Fi network, or that one is connected to the other’s Personal Hotspot.
2. In iPhone Settings, open Huh?’s permissions and make sure Local Network is allowed on both phones. You can also find it under Privacy & Security → Local Network.
3. If you are on a guest or public network, try Personal Hotspot. Some networks block phone-to-phone connections.
4. Return to Huh? on both phones. Tap Start over if the code has expired, then enter the new number.

We are connected, but I cannot hear sound.

1. Check the listening screen. If it says Paused, tap Resume.
2. Ask the person by the microphone phone to speak. If the microphone is muted, ask them to tap Unmute when they are ready. Check that Microphone access is allowed on that phone in iPhone Settings.
3. Check the listening iPhone’s volume and where its sound is going. Open Control Center, press and hold the music controls, and pick your hearing aids, AirPods or earbuds.
4. Bring Huh? to the foreground on the microphone phone. If sound still does not return, tap Stop and connect again.

The sound comes out of the phone, not my hearing aids or earbuds.

Huh? plays wherever the listening iPhone is sending sound. Reconnect your device in Settings → Bluetooth (or Settings → Accessibility → Hearing Devices for Made-for-iPhone hearing aids), then choose it in Control Center. Tell us your hearing aid or earbud model in beta feedback if it does not appear.

Just this phone is waiting and I hear nothing.

Just this phone (version 1.4) only plays through earbuds, headphones or hearing devices, never the phone’s speaker. Connect them first and it starts on its own. If your hearing devices are connected and it still asks you to connect first, use two phones for now and send us your hearing device model.

A phone call interrupted the session.

Wait until the call ends, then return to Huh? and check both phones. If audio has not returned, stop and reconnect. Include whether the call was on the microphone phone or listening phone in your beta feedback.

I hear echo, delay, or feedback.

The sound you hear directly in the room and the sound through your earbuds or hearing aids may arrive at slightly different times. Try another phone placement. Lower the volume or use earbuds if a phone speaker feeds sound back into the microphone. Tell us which devices and network you used; there is no single delay or compatibility result for every setup.

TestFlight asks for a redeem code.

You do not need a code. That box appears when TestFlight is opened on its own. Close it, open gethuh.com/get on the iPhone, and tap Open Huh? in TestFlight. Apple’s page opens; tap Start Testing, then Accept, then Install.

The invitation says it is not accepting testers.

The build may be waiting on Apple’s review or may have expired; TestFlight shows the current status. Try again later, or tell us at info@listerpros.com. Your iPhone also needs iOS 17 or later. If you already have Huh? in TestFlight, check for updates there.

What makes a useful report?

• What you were trying to do and what happened instead.
• Both iPhone models, iOS versions, and Huh? build number.
• Wi‑Fi or Personal Hotspot, and your hearing aids, AirPods or earbuds.
• What both screens said, and whether restarting helped.
