Efficiency apps/ task apps and MacBook help

[houserenohelp]

Hello

We are very busy at work I am overworked as we are in the middle of recruiting

I struggle to keep on task and focus due to ADHD

I saw a advert for programs to help you work more effectively
Anyone have any experience of apps or programs to help with this?

Also ways to help keep my Mac organised as it's become overrun with downloads etc
