hey guys. i have made a software which gives instant relief to patients suffering from ADHD, it has multiple frequencies that help to calm their mind and regain instant focus, it has different frequencies for different situations and some ancient technic which will help them in long run. i am a patient of ADHD and i have used it myself, so i know this thing works really well. but the problem i am facing is the price point at which i should sell it. its a personal saas install in your device and will run offline. as its a one time buy, do you think 100 dollars is a fair price? or shall i charge more?
