I was literally just thinking about something like this yesterday evening. Normally I let my empty tea/coffee/water/"need to go to the bathroom" remind me to get up, but that is super unreliable, of course. I was contemplating some bracelet/rfid reader that didn't let me stay in my desk chair for too long before alerting me.

I'm surprised that the button-switch under butt pillow worked as well as it did in my setup, I've been using it for over a year but I've made the software-setup unnecessarily complicated and so I'm rewriting it to be a single module with some bells and whistles.

RFID bracelet would work too, But I wanted my setup completely unattended. Please send me an email if you'd like to be updated about rebuild of Butt Pomodoro.

How do you tackle the problem of “alarm blindness”?

The moment I think about a ‘Butt Pomodoro’ I picture myself being 90% disciplined and 10% saying “ok yes but not right now: I’m (doing something with a critical deadline/in the zone/especially lazy)”

And after a few of those, the reminder becomes background noise.

Good question.

That's why I integrated pomodoro framework and didn't make a plain butt triggered alarm and so Butt Pomodoro is a time-management + health application not just a activity alarm.

I was already using Pomodoro schedule for time-management/productivity albeit triggering it manually now Butt Pomodoro helps me to trigger it automatically and pomodoro breaks are now for walks.
