iPhone Screenshots


This application is an iPhone-based stuttering therapy.
The application used such popular methods as DAF, FAF, and others.
With noise reduction and background mode, you don’t have to break away from everyday activities and look for a quiet place to study.
Already many users have confirmed positive results after using our application.

--1. Delayed auditory feedback (DAF). You will hear your voice with a short delay. This delay will reduce the speech rate and make you draw out the vowels.
Gradually reduce the time of delay until the speech rate increases up to the normal level.
NOTE: Bluetooth protocol adds some extra delay if you are using the DAF mode of the application with a Bluetooth headset;

--2. Frequency altered feedback (FAF). You will hear your voice sounding lower than it really is. The unique effect of speech morphing lowers the voice tone, relaxes the voice path muscles and reduces the frequency of stuttering.
The effect lowers the tone but your voice remains natural and recognizable You can adjust the level of tone lowering;

--3. Speech rate indicator. The display interface will indicate if you speak too fast;

--4. Training sessions mode based on random texts;

--5. Training sessions mode based on rhymed texts;

--6. Background mode for everyday communication;

--7. A course of exercises for training sessions.

--metronome for tempo and rhythm speech support;
--vibrating metronome to be used in the background mode when the smartphone is in your pocket;
--selfie videos during training sessions;
--adjusting the volume balance between the left and right ear;
--timer for training mode.

This app it’s complete trash

As someone who genuinely stutters I thought this was really going to help. Don’t waste ur time on this. The “exercises” have not been tested or calibrated at all. The text goes by way too fast. It even says I’m speaking very quickly but still can’t keep up?! The devs should be ashamed they release this trash.

Developer Response ,

If you touch the text, you can stop its movement.

Please, would you consider lowering the price?

I don’t know how you would expect a child/student to pay weekly $10 for an application. Thats a little much. I’m sure a lot more people would purchase it if it was one time purchase. But weekly?!?!

Not usable

In the exercises, the text scrolls faster than one can reasonably read quietly besides reading out-loud.
