  • I love this app so much! Sep 9, 2017

    By Charly Dat Duc Lai
    Lord and the developer of this app, you have healed me. For a long time, I've stuttered/stammered but today when I tried out this app after purchasing and downloading it, an incredibly amazing miracle just happened. I was finally able to speak much more fluently with a tiny stammer or no stammers at all. Thank you so much for developing this app for those who need this.

    The app is very good. However, I find that when I use bluetooth earbuds, the app keeps using the phone microphone. As a result, the volume is low, and I've found over the years that for DAF FAF to be effective you need high volume, not to hear the sound of your own voice. Personally, I would be more than willing to pay for a perfect FAF DAF app that manages to mask the sound of your voice and guarantees a more reliable experience, and I strongly encourage speechtools to add more tweaks.

    I have a speech disorder called cluttering, and this app has been a tremendous help. It is simple, yet very effective in helping me slow my rate of speech and improve articulation. And, the ability to record a sample and play it back for analyzing is a nice feature. Great app, highly recommended.

    It works magic. The only issue that I find (and which is rather important) is that when I use Skype, skype users can't hear me. It seems that it hijacks the microphone. However apart from that this is a really superb app which is very usefull.

    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.

    I recently installed this paid version. But it has following bugs: 1) not working with phone calls with my realme 5i device with android version 10. 2) It uses mobile phone speaker instead of wireless Bluetooth earbuds. So what is happening, even though i am connected with Bluetooth earbud but if my phone is keeping far to me, it produces very slow voice sound as it is using mobiles speaker not headsets. Please fix these two issue, your app is really great, and very helpful to stuttering people

  • Cannot use pitch change Jan 8, 2020

    By ReentWT
    Any change in pitch causes a static sound.

    Good simple controls.. Works well with Samsung Buds (bluetooth). It would be nice to have the min delay value above zero to compensate for latency in the procesing of the audio say Mike 40ms ?
  • scratchiness with any pitch change Aug 15, 2018

    works great with no change in pitch, but a scratchy noise is apparent with any change in pitch. tried other headphones, no difference.

    The app has SEVERE latency issues, and does not serve its purpose at all. I emailed the developers a couple weeks ago, and have still not received a response. Don't waste your money on this.

    Fix the Bluetooth mic capability. App outputs to headphones but doesn't receive input from microphone.
  • It would work great if Jan 27, 2020

    By Plants72
    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.

    Returning user - I used this app a few years ago and it was superb though became less effective over time so u installed. Reinstalled today but disappointed. Volume slider doesn't work, neither does lowering the pitch. The email link to speech tools us also broken. I'd love to use this app again but I can't use it effectively until pitch functionality is restored

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

    The delay at its shortest is far too long rendering it useless. I brought this android app due to its ability to be used in calls however its proving only to be an annoyance.

  • So far so good Sep 9, 2014

    By Pinger user76
    I have been stuttering for all my life, now 38 years old. I have researched several of the expensive items such as speech easy. I was very eager to spend the thousands for that item but then through further research, I found that apps have been developed. Currently I have downloaded 5 different apps. My main concern is that other apps with delayed auditory feedback seemed to be too delayed. Some have 0ms while others have 4 minimum. In these cases, there seemed to be a longer time response to hear myself, so it didnt help much. This app, though it shows the minimum delay is 23 ms, it seems much quicker than the other apps who show a shorter delay time. I just started working with this, so in about 2 weeks, I will try to post again to give appropriate feedback. So far, I like this app the most as the delay time is very quick so I can hear myself as soon as I am speaking.
  • Like the proverbial charm! Jul 27, 2012

    By ScribeJay
    This $10 app accomplishes what I could have spent hundreds of dollars on for dedicated hardware. The only reason I might not give it 5 stars is this: I know or can't work on a phone call, but sometimes when something else grabs the audio out , DAF doesn't grab it back afterwards. Oh well, 5 stars anyway.

    Thanks for providing an affordable alternative to the Speakeasy in-ear. I've experienced great results with this app.
  • Amazing tool Mar 2, 2012

    By TrainRiderDave
    DAF Pro is elegant and amazing! After a little experimenting with the amount of delay, I have some wonderful results. The app also runs in the background, so you can keep it running while you use other apps like email and web. Thanks for this amazing tool!
  • No use Mar 26, 2012

    By AveryKucan
    I have no use for it, but I use it as an amplifier. My mic built into my Sony earbuds with volume control is sensitive, so i use it As an amplifier for my bad hearing. Delay all the way down, volume up on system and app, and there ya go!
  • Awesome!!! Feb 6, 2012

    This app has been extremely helpful when working with my stuttering clients. I'm still trying to figure out how to work it on my iPad but it works great on my iPhone!

    Works well, but would it be possible to add an option to automatically start the auditory feedback when the app starts?

    Practically useless application. The "zero" delay is too long for normal speaking. It's impossible to make a short delay. Cannot use for normal conversation, public speech and...... The support not responding.
