Data only push notification -> text to speech to bone conduction headphones (or really any headphones). Tells me the current task. Two buttons on my wrist. One is next task, one is "toggle repeat mode". I have voice actions that load specific lists or any of the other things I want it to do. Basically all manner of software exists in varying forms for working on basically every native user interface I interact with. Global hotkeys, system tray icons, background services, etc etc.
The cli, custom launcher, watch software, and the chrome / firefox new tab extension get the most use. Small feature set makes "software for everything" realistic. "See/hear current list item", "Next task", "toggle repeat" -- I treat it as a way to learn things, but I also use it absolutely every day. I like to act like when I inevitably develop cognitive issues in my old age that this will be a useful utility to have.
When I make a very detailed list for the day and burn it all down by just listening to what I'm supposed to do and tapping a button on my wrist for the next thing, I feel far far more productive than my baseline just due to not context switching. Put up the blinders, get in the zone, stay in the zone. :)
