I don't see anything wrong with it. Surely a lot of people with ADHD would be happy to pay for an app that helps them overcome their problem, and the monetary price most likely exceeds the benefit (assuming the method used by this app works as advertised). In fact the price is much cheaper than a regular visit to a therapist. The problem I see here is the current subscription model. If people are happy with the trial, and see results, they would be happy to subscribe for a monthly fee along with their Netflixes and Spotifys.
