DAF/FAF Software

DAF/FAF Software I have a phone interview coming up tomorrow and I was wondering if anybody had ever used DAF/FAF software to help control or reduce their stuttering? I have downloaded software from [Fluency Coach](http://www.fluencycoach.com/) & [DAF Pro](https://speechtools.co/daf-pro) but neither of them work in the background while I'm on a call which kind of defeats the purpose. Are there any other apps or software out there that are recommended to help control or reduce stuttering?
