I also have ADHD and also recently got into knitting. I’m curious if you’ve run into trouble keeping count at all? I find my biggest struggle is getting into a rhythm only to find I’ve dropped out added a bunch of stitches after it’s too late
Of course, you will still have to remember to increase your row counter at the end of each row. I have a row counter I keep hung around my neck, so it's easily accessible. A physical row counter (as opposed to an app) is better for this. I really like this cheapo one: https://www.amazon.com/Clover-Knitting-Stitch-Counter-Kacha-...
The first afghan I crocheted, I probably pulled out as many stitches as I successfully created. But, that's how you learn.
