Kalox is a calisthenics training companion built for people who train with their own bodyweight — at home, in the park, or at the gym. TRAIN YOUR WAY Pick a generated program tailored to your goal, equipment, and schedule — or chase a specific skill like the planche, front lever, handstand, muscle-up, or pistol squat through step-by-step skill trees. Prefer to freestyle? Just log your workouts and Kalox keeps track. CAMERA COACH Point your phone at yourself during push-ups, squats, pull-ups, and hangs. Kalox counts your reps in real time using on-device pose tracking, scores your form, and gives you concrete cues to improve. Your camera footage is processed entirely on your device and is never uploaded. SKILL TREES Five full progressions — planche, front lever, handstand, muscle-up, and pistol squat. Take a quick assessment, get placed at the right level, and unlock the next step as you complete sessions. No missed-day guilt: your program advances when you train, not when the calendar flips. TRACK YOUR PROGRESS Workout diary, weekly goals, streaks, personal records, and progress charts — all stored privately on your device. BUILT FOR FOCUS Guided workout sessions with rest timers, set-by-set tracking, warm-ups and cool-downs, and a clean dark interface that stays out of your way while you train. PRIVATE BY DESIGN Your training data never leaves your phone.
