Vyyz is a privacy-first water intake tracker designed exclusively for iPhone 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 water with a single tap. The interface is deliberately simple – tap the plus button, and you're done. No unnecessary steps, no social features, no distractions. Vyyz learns your most-used amounts and adapts to your habits.

Complete Privacy.
Your water intake data never leaves your devices. Everything is stored locally and synced through 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.

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.

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.

What Vyyz Doesn't Do.
There are a thousand Nos to every yes. In a world where everyone wants to track you, analyze and monetize you, Vyyz is different: no advertisements, no sponsorships, no tracking, no data collection, no monetization, no nagging to upgrade.

Subscription required after trial period.
