I used to think those 'smart' water bottles were just overpriced junk
About a year ago, my buddy got one that glows when you need to drink. I thought it was dumb, but he kept using it. Fast forward to last month, I saw him again and he actually drinks way more water now, like he fills the thing three times a day. He said the little light reminder just got him into a habit without him thinking about it. It made me look around, and now I see them everywhere at the gym, not just with tech people. The change seems to be that they went from a flashy gadget to something that actually helps build a simple habit. I'm still not sold on paying $80 for a bottle, but the core idea of a gentle nudge might stick around. Has anyone else had a friend who totally changed a habit because of one of these things?
