Xstatic

Hey Product Hunters! I’m 33 and plagued by back pain after hours of sitting, and while we all know those stand-up reminders exist, they usually require a smartwatch. I wanted a simple way to nudge myself to shift posture and even get a mini “massage” via vibration without extra hardware—so I built Xstatic: a free iPhone app you tuck against your lower back or slip in your pocket, and it gently buzzes when you’ve been too still to remind you to stretch, adjust, or just move. I’ve been using it for days and already feel the difference—how do you tackle prolonged sitting, and what would you love to see in Xstatic?
