Subjective context meets objective trends.
Check-ins give the coach the full story behind the numbers. Numbers tell part of the story. How you feel, sleep, and stress levels explain the rest.

Adaptive check-in structure

Coaching with full context
The AI coach uses check-ins alongside performance data to recommend changes that match how you are actually responding—not just what the program says.
