Make sure the headset is connected, then allow the microphone.

Hearing Helper
Amplifies the room into your bone-conduction headset, with separate Left / Right control.
Tap Start, then allow the microphone.
12 dB
Total loudness, like a hearing aid's gain. Start low and raise slowly so it never hurts.
⚠️ Very high power — if you hear squealing (feedback), lower this or move the phone away from the headset.

If one ear hears worse, lower the stronger ear and raise Overall Volume.
6 dB
Tone shaping, not loudness — boosts the high tones that make words crisp (consonants like s, t, f). For more loudness use Overall Volume above.
Settings already save automatically on this phone. Use Save to keep named setups (e.g. “Dad”), and Backup & transfer in Advanced to move them to a new phone.
Advanced settings ▾
🎙️ Voice commands experimental
Say the wake phrase, then a command: “Hey Helper, louder” — also “softer”, “left up”, “right up”, “even”, “clearer”, “stop”. Works best on Android Chrome; may not work on iPhone, and it uses the internet.
Require wake phrase
Stops the app reacting to ordinary conversation. Recommended ON.
Start automatically
Show a big “tap to start” when you open the app, so there's nothing to hunt for.
For stereo + Left/Right balance, keep this on the phone mic. You can pick the headset mic for hands-free use with the phone away — but Bluetooth then drops to mono, call-quality and balance turns off.
🎧 Headset mic in use → mono. Bluetooth can't do stereo output and headset-mic input at the same time, so Left/Right balance has no effect and sound is call-quality. Switch back to the phone mic for stereo.
Selected-mic input level
Reduce background noise
Calms steady hiss/fans. May slightly muffle speech.
Quiet-room gate
Mutes faint background between speech. Leave OFF to hear soft voices.
Auto-leveling
Evens out loud and soft sounds (compression). Recommended ON.
Sweeps several speech tones in each ear (about a minute) and builds a custom per-ear sound profile. Not a medical audiogram — a relative self-fit you can fine-tune.
No limit
Override anytime: drag down if loud sounds bother him, or slide to the far right (No limit) to remove the cap completely. Or tap “Set by ear” for the guided test. If he ever can't hear well after an update, set this to No limit first. Comfort setting — not hearing protection.
Backup & transfer
Save this code somewhere safe (text it to yourself, or keep it in Notes). On a new phone, paste it here and tap Restore to bring everything back — including the hearing-test profile.
🩺 Audiologist mode ▾
Professional configuration aid — not a hearing aid. For a hearing professional to shape sound using their own clinical judgment. It does not diagnose, test, or treat hearing loss.
Per-ear gain (dB)
The clinician sets the boost for each speech band, per ear. The app does not calculate these from a hearing test.
“Config code” is a shareable text snapshot for tele-fitting — paste it under Advanced → Backup → Restore on another device.
⏱️ About the small delay: over Bluetooth there's roughly a ¼-second lag. It's fine for listening to someone in a quiet room. When you talk you'll hear a slight echo of your own voice — that's normal for this kind of device. Face the speaker so you can also read lips.
