Intelligent Scaling
Hydra calculates your daily goal based on your weight and activity level, adjusting dynamically as you progress.
Vibrant Insights
Interactive charts and historical data grouped logically to show you exactly how your habits are evolving.
Privacy by Design
We don't collect your data on our servers. All your hydration logs stay local, private, and secure on your device or your personal Google Drive.
Home Screen Widgets
Log your water with a single tap from your home screen. Now responsive in 2x2 grid fits securely for all scaling presets.
Smart Reminders
Never miss a glass. Configure smart notification pushes intervals with Quick Log action shortcuts directly from alerts boards.
Tactile Haptics
Premium tactile click responses mapped throughout accurate interface weight parameters forwards seamlessly.
- Smart Review Flow:5 trigger-based review prompts (goal, streak, personal best, challenge, 7-day streak) — each with its own cooldown and Remote Config thresholds.
