Summary

This study tested a system called sipIT that uses a smart water bottle and phone app to track fluid intake and send reminders. The goal was to see if it helps kidney stone patients form a habit of drinking more fluids. 172 adults with a recent kidney stone diagnosis used the system for 3 months. The study focused on understanding how behavior change works, not on directly treating stones.
