Muffl

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. MUFFL PRO Free: the Dinner profile, up to 3 triggers, 45 minutes of shield a day and 3 days of diary. Muffl Pro removes the daily limit and unlocks every trigger and your own sounds, all profiles, all 8 masking sounds with spectral fitting, Apple Watch control and the full diary with export: yearly with a 7-day free trial, monthly, or a one-time lifetime purchase. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the period; manage them in your Apple ID settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://evgeniybruchkovskiy.github.io/muffl-legal/privacy.html Muffl helps you get through trigger sounds. It is not a medical device, does not diagnose or treat any condition and does not replace working with a specialist.

Verdict
The clearest difference is ads: Muffl at none against Deep Belief's shown. Deep Belief's advantage is iOS requirement (15.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
