Vyyz is a privacy-first water and drink tracker designed exclusively for iPhone, iPad, and Apple Watch. Built with native technologies and a deep respect for user privacy, it helps you stay hydrated without compromising your personal data. One-Tap Logging. Add your usual with a single tap. The interface is deliberately simple – tap the plus button, and you're done. Vyyz learns your most-used amounts and adapts to your habits over time. Complete Privacy. Your water intake data never leaves your devices and your private iCloud account. Apple Watch App and Seamless Multi-Device Synchronization. Log your water intake anywhere and see it instantly on all your devices. Widgets and Apple Watch. Quick Add widgets on the Home Screen log your favorite amounts with one tap, a Daily Chart widget shows the day so far, and a Lock Screen gauge shows your progress. A complication that isn’t really all that complicated. Monitor your progress on your Watch with just a glance. Smart Reminders. Set your active hours and reminder frequency. Vyyz respects your schedule, sending gentle nudges only during your specified times. When you reach your daily goal, reminders automatically stop. Weather-Based Intelligence. Enable weather notifications to get extra reminders on hot days or when UV levels are high. Simply choose a city close to you from a pre-loaded list. Works with Apple Health. Using Vyyz with the Apple Health app helps you build a more complete picture of your wellness. With your permission, Vyyz can write water intake data to the Apple Health app, and read manual entries or data from other hydration apps. Drinks and Nutrients. Log your water intake, but you can add your own drinks, too: juice, coffee, sports drinks, anything you pour. Scan the nutrition label with the camera, and Vyyz reads the sugar, caffeine, sodium, vitamin C and minerals content, and logs them to Apple Health with every serving. Personalized Goals. Set your daily goal manually or use an intelligent calculator that considers your age, weight, activity level, diet, lifestyle and other factors. Based on guidelines from EU and US health authorities, it provides personalized recommendations. Privacy: https://vyyz.app/en/privacy/ Terms of Use: https://vyyz.app/en/terms/
