Please speak to your Speech Pathologist about the efficacy of Delayed Auditory Feedback (DAF) before purchasing Simply DAF. It is meant to be used under the guidance of a qualified medical professional.
Simply DAF requires iOS 8.2 or above.
Simply DAF is designed to be very simple to use. You can pick your preferred delay (in milliseconds) by swiping up or down on the carousal. Once you are close to your number, you can tap once above or below the selected delay to step through the delays one at a time. Once you've picked your delay, tap the big START button. You'll need to have your headphones plugged in to your iPhone. Speak into the microphone near your lapel and adjust the volume to your desired comfort level.
The app will work in the background as you use other apps. For example, you can run Simply DAF and then launch iBooks to practice reading aloud while running DAF. However, the app will not work during a phone call or with other apps that generate sound or music.
