Read full descriptionHide full description
HydrateTap β 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 β a face scan, urine scan and skin test build an honest 0β100 verdict, entirely on your device. And logging is still one tap from a widget. No menus, no friction, no excuses. HYDRATETAP CHECK β YOUR BODY, MEASURED Three guided exams, nothing but your phone: β’ Hydration Check β a face scan, urine-color scan and the clinical skin-pinch test, combined into one 0β100 verdict with every tool's finding explained. β’ Heart Recovery β a guided 3-minute test: rest, 30 camera-counted squats, recover. Your fitness as one honest index, tracked over time. β’ Morning Readiness β your night, scored from sleep, resting heart rate and HRV. All on-device β your face, scans and signals are never uploaded. No account needed. HYDRATETAP CARE β HYDRATION, GUIDED On a GLP-1 medication? Your thirst signal goes quiet β 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: β’ GLP-1 Support β for Ozempic, Wegovy, Zepbound & Mounjaro users. A paced daily target, dose-day reminders, and a log for the side effects steady fluids can ease. β’ Kidney Stone Care β urology guidance puts one habit first: dilute urine, all day. Evenly paced 2.5β3 L days and an adherence report for your urologist. β’ UTI Support β 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. β’ Fluid Limit β a reverse tracker for clinician-set restrictions (heart failure, dialysis): the ring fills toward your ceiling and warns you before you cross it. β’ 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 β never replaces β 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. THE FASTEST WATER TRACKER β’ One-tap logging from beautifully designed Home Screen widgets β’ Live Activity & Dynamic Island β your progress, right on the Lock Screen β’ Apple Watch app with drink detection β log straight from your wrist β’ Smart reminders that notice hot days and workouts β and go quiet once you're done β’ Works offline β every sip syncs when you're back online BEAUTIFUL, PLAYFUL, MOTIVATING Watch living water rise, refract and celebrate every sip. Dive into The Depths β an underwater ocean that opens metre by metre as you drink. Meet the Water Guardians: nine keepers, each dressing the whole app in its own world β earn them by keeping your streak alive. Cheers with a friend: clink your phones and you both log a glass. FREE, CHECK & CARE The free version delivers what other apps hide behind paywalls: instant widget logging, smart reminders, streaks and full daily tracking β forever. HydrateTap Check (subscription, 7 days free) unlocks the Check instrument, trends, The Depths, all Water Guardians and Apple Health sync β or own it forever with a one-time lifetime purchase. HydrateTap Care adds every guided care plan, paced protocols and clinician reports β with a free week to try it. Install HydrateTap, place your widget, and log your first glass in one tap. Because when staying hydrated is this easy, you'll actually stick with it.
