I started going full 90s and buying devices which serve a singular purpose nowadays usually performed by a smartphone app. So far I have:

-A rotational timer which you, well, rotate and it times.

-A whiteboard which serves as my todo list.

-An mp3 player.

-Regular old satnav in my car.

-Remote-controlled LED in my bedroom.

I'm also thinking of using a regular watch again after an almost 20-year hiatus.

All this just so I won't get tempted to check social media each time I'm trying to perform an unrelated task.

It's ridiculous, but these are the lengths I'm willing to go to fight this.
