I’m looking for a very simple wrist wearable/band/watch that gives a gentle vibration or buzz at intervals as a reminder for posture/focus.
I don’t need fitness tracking, notifications, calls, or even a display. A screenless band/watch is completely fine. I just want something lightweight on my wrist that can silently vibrate every 20–30 minutes (or custom intervals) so I remember to correct my posture or stay mindful while working.
Does anyone use something like this or have recommendations?
