Muffl: Soften Trigger Sounds

Muffl listens, but records nothing and sends nothing.

When a sound you find hard appears — chewing, crunching, sniffing, keyboard tapping, a pen clicking — Muffl gently covers it with a soft layer of sound in your headphones. When it's quiet again, the layer fades away. The rest of the time you hear people as usual, so you can stay at the dinner table instead of leaving it.

HOW IT WORKS
• One big button. Turn the shield on from the app, Control Center, the Action button, Siri or your Apple Watch.
• Pick the sounds that are hard for you: chewing, crunching, lip smacking, slurping, sniffing, heavy breathing, snoring, keyboard typing, pen clicking, tapping, a spoon on a cup.
• Situation profiles: Dinner, Office, Transit, Cinema, Sleep next to snoring — each with its own triggers, masking sound and strength.
• Eight masking sounds, generated live so they never loop or click: soft rain, rustling leaves, a brook, pink and brown noise, a low hum, café murmur, a warm fan.
• Spectral fitting shapes the sound to the trigger's pitch, so it works at a lower volume.
• Teach Muffl a sound of your own from a few examples.

AFTERWARDS
• A quiet diary of episodes and how they felt, with CSV and PDF export for your therapist.
• A 30-second breathing circle when a moment was hard.

PRIVATE
• Audio is analysed in memory on your iPhone — nothing is written to storage and nothing leaves the device. No account, no ads, no analytics.
• Optional iCloud sync for the diary uses your own private iCloud database.

HONEST ABOUT LIMITS
Muffl cannot remove sounds from the room and cannot switch your AirPods' modes. It adds a masking sound at the right moment. Best with AirPods Pro in Transparency mode; any headphones work.
