Doesn’t work!!

Bordprson on

Since there’s no way to message the creators of this app, I’ll do it here. I just downloaded this app. It says it’s ‘supposed’ to be super simple to use. Well, if you are looking for an app that only produces a LOUD LOUD buzzing sound in your ears, this is the app for you. It’s so loud that I could practically feel my teeth vibrating and turning down the volume made no change in the ridiculously loud vibrating sound this app created. If you want to actually hear your own voice in hopes of stopping or lessening your stutter, look elsewhere because this app can’t hear your voice over its own incessant, brain numbing buzzing. I am using an iPhone 14Pro and 1st Gen AirPods. I know they are both working correctly because I just finished a Duolingo session and had no problem completing today’s lesson. Sound and mic worked just fine. What a waste of $4.99!

This works.

I been stuttering for over 50 years and I used everything from speecheasy devices to taking classes. This works just like the speecheasy without spending $4000. But pros and cons of both. Thanks so much for helping me with this. Anywar to get this to work with a hearing air

This App isn’t it

Bought it for nothing. Wasted money for it to be super muffled and robotic can’t even hear yourself. Don’t bother

Excellent app

App operation is straightforward and clean. The clarity of the audio and delay is also top notch. Highly recommend use of the app as an additional tool for the management of stuttering.

It would work great if

I have to use another DAF app because I’m using AirPods and there is too much delay for me. Can you make no delay like other apps. 23 ms delay and Bluetooth delay is way to much for me.

Cannot use pitch change

Any change in pitch causes a static sound.

Thank you so much

From the bottom of my heart, thank you. I work in a call center and I have a stutter. I put an earbud in and put it on 55ms. I don’t stutter at all on the phone now. Then I forgot to put my earbuds in and I didn’t stutter. Hoping it will improve my speech overall after the repetition. It also helps me slow down my speaking and makes me feel calm. This app is priceless. Best 3 bucks I ever spent in my life. I feel hope that I will be able to speak fluently now. This has changed my life. Thank you and god bless

Thank youuuuu so much
