If there is one app that can help/reduce stutter, what specifically you wish the app can help you with? With the advancement of AI, building an app is easy. But solving the correct problem is hard. I am a software developer and a stutterer myself, but I do not know what exactly caused it. Building solution without knowing a problem is difficult, that's what this post is about, to ask a problem you wish to overcome. It can also be the case where stutter is not something that can solved by app. Idk, so i am here to just ask.
