Kreas vs Hydra

Stop guessing your creatine levels. Whether you're in a loading phase or maintaining, Kreas uses a dynamic saturation model to show you exactly where you stand. Most trackers just log data. Kreas understands the science. If you miss a dose, Kreas calculates your dip in saturation and shows you the benefit of getting back on track. Why Kreas? - Saturation Tracking: See a real-time estimate of your muscle creatine levels based on your actual intake and missed days. - Smart Reminders: Get notified before your saturation levels drop, or if you're on track to miss a dose. - The Loading and Maintenance Phase, Simplified: One-tap logging for multiple daily doses during your loading and maintenance weeks. - Visual Progress: A clean, intuitive calendar view to visualize your consistency streaks. - Supply Tracking: Include your creatine supply in the app and know when you're about to run out Built for focus: - No Clutter: No social feeds, no "pro tips" you didn't ask for. - Total Privacy: Your data stays with you. No accounts, no tracking. - Zero Ads: Focus on your gains, not banners. Stop guessing. Start saturating.

Hydra is a hydration tracker built around a single gesture: drag up anywhere on the home screen and watch the water rise to where you logged. Most water apps use a generic 2L target. Hydra calculates yours from your weight, sex, activity level, and climate — then bumps it up automatically when you take creatine. Because creatine pulls water into your muscle cells, you actually need more.
