one of the scummier ads i've been shown is for "happyo", after digging in, it's just a collection of some lame ass planner apps. it costs $3 for the first week, but then jumps up to $67.99 for the next 3 months. to me, what they're doing is predatory.
my 2 cents is just go through some telehealth platform and find a therapist who specializes in ADHD that is covered by your insurance. if your copay is $25 for an HOUR session.... then 1 visit a week is only $100/mo. and if you want to go "immersive", schedule 3 visits a week lol
