This is not true at all. If anyone is considering ADHD therapy, please do not let such misleading figures dissuade you.
For anyone with insurance, the average cost of a therapy session is often as little as a $15-25 copay. You could get 4-6 in-person, personalized therapy sessions with an experienced provider for the same price as the annual fee of this app, depending on your insurance.
Even self-pay therapists don't charge $200-300 unless you look at the most expensive cities like NYC [1]. The average self-pay cost is going to be closer to $125 in most regions, though providers often have what's called "sliding scale" charges for low-income patients that go much lower.
The $10K-$16K per year figure is also extremely misleading. In the United States, the annual out-of-pocket maximum for an insurance plan is capped at $8,700 for an individual in a given year [2]. Mental and behavioral healthcare is covered as an essential health benefit [3]. It's not possible to spend $16K per year on any services unless you attend providers that don't accept insurance, which is exceedingly rare. Don't let any apps scare you away from professional services by quoting unbelievably high numbers.
If anyone is considering therapy, please visit your health insurance website and check the cost. Don't be discouraged by anyone trying to sell you alternatives. For most people with insurance (including government health insurance in the United States), several sessions are going to be cheaper than this app and will also provide more personalized, in-person care.
