HydrateTap — the fastest water tracker, now with Check: your phone reads your body. Plus guided hydration care plans. When did you last actually check your hydration? Point the camera — a face scan, urine scan and skin test build an honest 0–100 verdict, entirely on your device. And logging is still one tap from a widget. No menus, no friction, no excuses. HYDRATETAP CHECK — YOUR BODY, MEASURED Three guided exams, nothing but your phone: • Hydration Check — a face scan, urine-color scan and the clinical skin-pinch test, combined into one 0–100 verdict with every tool's finding explained. • Heart Recovery — a guided 3-minute test: rest, 30 camera-counted squats, recover. Your fitness as one honest index, tracked over time. • Morning Readiness — your night, scored from sleep, resting heart rate and HRV. All on-device — your face, scans and signals are never uploaded. No account needed. HYDRATETAP CARE — HYDRATION, GUIDED On a GLP-1 medication? Your thirst signal goes quiet — and dehydration, nausea and headaches follow. HydrateTap Care paces your fluids through the day, with extra support on your dose day, so your body never runs low. Eleven care plans for the moments hydration matters most: • GLP-1 Support — for Ozempic, Wegovy, Zepbound & Mounjaro users. A paced daily target, dose-day reminders, and a log for the side effects steady fluids can ease. • Kidney Stone Care — urology guidance puts one habit first: dilute urine, all day. Evenly paced 2.5–3 L days and an adherence report for your urologist. • UTI Support — in a randomized trial (JAMA Internal Medicine), an extra 1.5 L of water a day roughly halved recurrent infections. This plan turns that finding into a daily rhythm. • Fluid Limit — a reverse tracker for clinician-set restrictions (heart failure, dialysis): the ring fills toward your ceiling and warns you before you cross it. • Plus: POTS & Dysautonomia, Migraine Hydration, Bladder Training, Senior Care, Post-Bariatric, Medication Hydration, and Fasting Support. Every plan includes paced dose reminders, urine-color check-ins, symptom logging, and a clean one-page PDF report to bring to your next appointment. HydrateTap Care supports — never replaces — professional medical advice. It is not a medical device and does not diagnose or treat. Clinician-set targets always take priority, and if your fluids are restricted, use only the limit your clinician set. Check results are wellness estimates, not medical measurements.
