This device has significant potential for use particularly among stone former that have demonstrated difficulty increasing their hydration as a part of preventative care. The device would not only allow users the ability to closely monitor their fluid intake throughout the day, it would also engage the patient with reminders to drink periodically throughout the day and stay hydrated. Additionally, fluid intake measurements stored through the associated application have the potential to be used as a novel metric capable of being brought to the provider's attention in order to better assess and guide patient hydration status and identify barriers to achieving hydration goals.
