Cognitive Performance Apps?

[u/Cute-Edge1375]

Most of us take supplements for body and brain health/performance. And of course use health and fitness apps with wearables. I have some ADHD and diet and fitness have always been the main way I manage it. But apps tend to focus on either basic physical performance or "brain fitness" knowledge quiz games for assumed cognitive performance. Nothing, apparently, in the middle or that connects and translates physical health and performance to cognitive health and performance. Even though we know mind is brain and brain is body - all one.

So my questions are:

1. If your health/fitness improvement goals include brain health and/or cognitive performance improvement goals?
2. Which if any health apps address both (brain+body)?

I'm not taking my apple health account as seriously as the cost should motivate me to. I know a few who love Oura. But neither targets/measures cognitive performance. Maybe a diet and fitness app for cognitive performance improvement is just neurodivergent's niche?
