Calx is an AI fitness coach that actually knows you.

Most fitness apps hand you a generic plan and leave you to it. Calx learns your body, your goals and your routine, then adapts every day — the way a real coach would.

TALK TO YOUR COACH, OUT LOUD
Call your coach and have a real conversation. Ask what to eat before training, why you feel flat today, or how to fix your form. It remembers what you told it last week.

NUTRITION WITHOUT THE TEDIUM
Point your camera at your plate and Calx logs it — calories, protein, the lot. Get a daily target built from your body, your goal and your activity level, not a one-size-fits-all number.

TRAINING THAT MOVES WITH YOU
Personalized workouts that adjust to your progress, your equipment and how recovered you actually are. Log sets fast between rounds with a built-in rest timer.

RECOVERY YOU CAN SEE
Connect Health Connect to bring in steps, sleep, heart rate and weight. Calx turns that into a readiness score and a clear verdict: push hard today, or back off.

TRACK WHAT CHANGES
Progress photos, weight trends, body-fat estimates and a transformation timeline that shows how far you have come — not just today's number.

STAY IN IT
Streaks, Aura points and challenges keep you honest. Join communities, share progress and train alongside people chasing the same thing.
