Each morning, you’ll get a personalized fitness index based on key indicators like sleep quality, heart rate, training load, and nutrition. No more guessing — know exactly where you stand and what your body needs.

Track your trends over time with dynamic visual charts. See how your fitness evolves across weeks and months, and pinpoint what drives your growth — or what’s holding you back. Dive into factor analysis to uncover how rest, stress, and recovery are shaping your condition.

Enter your daily data in seconds — whether it’s how well you slept, your morning heart rate, or how intense your training was. The more consistent you are, the more accurate your insights become.

With smart recommendations and daily targets, you’ll know when to push harder and when to take it slow. Overtraining? Under-recovering? The app shows the patterns before they turn into setbacks.

Whether you're a high-performance athlete or just starting your fitness journey, this app adapts to your level and helps you level up.
