Verified Hydration Adherence for Patients
Managing Chronic Conditions

Water.io Care is a verified hydration intake platform that measures fluid consumption and confirms adherence to physician-directed fluid management plans for patients managing chronic and acute conditions.

Water.io Care exists to ensure you stay on protocol with what your doctor is prescribing
Water.io Care measures how much fluid you consume, compares it to your physician's prescribed target, and gives your care team the verified data they need to support your treatment.

Physician-Directed

Fluid targets are set according to your doctor's prescription.

Objectively Verified

Every sip is measured and recorded. Adherence data replaces self-reporting, which clinical literature shows is consistently unreliable.

Clinically Shared

Intake records are accessible to your care team, enabling real-world monitoring between clinic visits and supporting informed treatment decisions.

Where Physicians Prescribe Specific Hydration Protocols
Across a range of chronic conditions, physicians prescribe specific daily fluid targets. Non-adherence is clinically significant and, until now, impossible to verify outside a clinical setting.


Recurrent UTIs

A landmark randomized clinical trial found that increasing water intake by 1.5L per day reduced UTI recurrence by more than 50% in pre-menopausal women. Increased daily fluid intake is now a first-line clinical recommendation for UTI prevention. Water.io Care gives physicians the objective intake data to monitor whether patients are meeting their prescribed fluid targets.

Chronic Kidney Disease

Clinical research shows adequate fluid intake may slow CKD progression and reduce the risk of acute kidney injury. Physicians routinely prescribe specific daily fluid targets, yet patient adherence at home is clinically unverifiable without objective tracking. Water.io Care provides the longitudinal intake record physicians need to assess adherence between visits.

IBS & IBD

Rome IV criteria — the gold standard for GI disorder classification — recommend increased fluid intake to reduce constipation, symptom flares, and inflammatory triggers in IBS-C and IBD patients. Fluid targets are prescribed but have no objective monitoring mechanism outside a clinical setting. Water.io Care closes that gap.

Congestive Heart Failure

CHF patients require precise fluid management — often restricting to 1.5–2L daily. Exceeding prescribed limits contributes to decompensation and avoidable readmission. Water.io Care gives care teams remote visibility into whether patients are staying within their physician-prescribed fluid range.

Type 2 Diabetes

Clinical guidelines recommend specific hydration targets for patients with diabetes to support glycemic regulation and kidney function. Patients with comorbid kidney involvement often carry both minimum and maximum fluid targets.

Post-Surgical Recovery

ERAS surgical recovery protocols prescribe specific hydration targets to reduce the risk of post-operative complications. Remote verification of adherence to those targets is a documented clinical need across surgical specialties. Water.io Care provides the objective fluid intake record to support monitoring during the recovery period. Source: ERAS Society Guidelines: Perioperative Fluid Management, 2021

Physicians Can Prescribe. 
Adherence Cannot Be Verified.
Fluid intake instructions are among the most commonly issued — and least verifiable — clinical recommendations. Self-reported intake is well-documented to be unreliable. Water.io Care closes this gap.
The Problem
  • Patients are given specific fluid targets with no objective method to track them
  • Self-reported intake is documented across clinical literature as consistently inaccurate
  • Physicians have no visibility into real-world fluid behavior between appointments
  • Caregivers managing high-risk patients lack any remote monitoring tool for hydration
  • Non-adherence to fluid protocols drives preventable hospitalizations and acute episodes
The Solution - Water.io Care  
  • Proprietary cap sensor measures fluid intake volume with every sip, objectively
  • Eliminates self-reporting — timestamped intake records replace patient memory
  • Real-time data accessible to caregivers and care teams via companion app
  • Daily, weekly, and trend reporting supports documentation at follow-up appointments
  • Physician-configured target-setting aligns each patient's goal with their prescribed protocol
