Pick up your drink and show your cup or bottle to complete the reminder. Most water reminders are easy to swipe away—and just as easy to forget. Unlike regular reminders, make drinking water something you have to do HydrateLock you should Pick up your drink and show your cup or bottle to complete the reminder. HydrateLock is built for the moment when a normal notification is not enough. Set your preferred water times, get a short 30-second chance to act, and then receive a persistent alarm. To complete the reminder inside HydrateLock, pick up your drink and show your cup or bottle to the camera. No complicated water logging. No calorie-style dashboards. No guilt. Just a focused reminder that helps turn “I should drink water” into a small physical action. HOW HYDRATELOCK WORKS 1. Choose the times you want to be reminded. 2. When a reminder begins, HydrateLock starts a 30-second grace countdown. 3. If you have not acted, the reminder becomes a persistent system alarm. 4. Open HydrateLock and show your cup or bottle to complete the reminder. 5. Your local daily progress updates automatically. WHY DOES IT LOOK FOR A CUP OR BOTTLE? Because the goal is not to make hydration feel like a test. The goal is to get your drink into your hand. Once you remember—or physically pick up your cup—you are already much closer to taking a sip. HydrateLock deliberately focuses its on-device recognition on common drink containers instead of trying to understand every possible hydration behavior. This focused approach keeps the experience fast, lightweight, and reliable while reducing unnecessary complexity and mistaken detections. It is a purposeful product choice, not a lack of intelligence: HydrateLock uses smart recognition only where it helps you act, without adding more work or pressure. HARDER-TO-IGNORE WATER REMINDERS HydrateLock uses iPhone system alarm experiences so your reminder can remain visible beyond an ordinary notification. The countdown and active reminder can appear through system surfaces such as the Lock Screen, Live Activities, and Dynamic Island on supported devices. You always retain access to iPhone’s system controls. HydrateLock does not attempt to block or override them. FEATURES • Persistent water alarms • 30-second grace countdown • On-device cup and bottle recognition • Flexible daily reminder schedule • Today view with upcoming reminder times • Local daily progress and completion history • Automatic camera opening when an active reminder is detected • Clear permission and privacy controls • No account or sign-in • No subscription, advertising, or analytics in version 1.0 • No cloud connection required PRIVATE BY DESIGN Drink recognition runs entirely on your iPhone using on-device machine learning. Camera frames are processed only while verification is open. They are not saved, uploaded, or shared. Your reminder schedule, settings, and completion history stay in local app storage. HydrateLock does not require an account and does not build a profile about you. SIMPLE, NOT STRESSFUL HydrateLock is designed for people who already know they want to drink more regularly but keep dismissing ordinary reminders. It focuses on remembering and acting—not measuring every milliliter or judging whether you reached a perfect daily score. HydrateLock recognizes the presence of a cup or bottle. It does not measure water volume, verify swallowing, calculate personal hydration requirements, provide medical advice, or diagnose, prevent, or treat any condition.
