I had something similar to that one, but it was a browser extension... Was using it for some time, but I forgot it very often... so I would need a reminder to my reminder... loool...

Currently, I'm not using any, except my "notes app" on the phone where I write ideas for future posts... I have built a lot of habits, which helps a lot, and if I want to add something to my daily routine, I add max 1 thing for a week, or two... After that, it gets into a new habit, and I can continue building it... :)

But, using reminders and checklists is a good way to battle against distractions!
