About this app

One app for the work you do—and the coach that already knows it.

Cipher connects your training, nutrition, activity, and body progress in one fitness record. Iron,
Cipher’s AI coach, can use that context to help plan your next workout, log meals faster, and check in when something needs attention.
TRAIN WITH DETAIL

• Track exercises, sets, reps, weight, RPE, distance, time, and notes
• Save workout templates and follow structured programs
• Use rest timers and guided targets during active workouts
• Review personal records, training volume, exercise history, and consistency
• Open Iron during a workout with the current exercise and completed sets already in context

LOG FOOD FASTER

• Track meals, calories, macros, saved meals, and favorite foods
• See daily nutrition targets and what remains
• Ask Iron to help log food using natural language
• Analyze food photos and review estimates before logging
• Adjust or undo supported Iron food-log receipts when something needs correction

SEE PROGRESS IN CONTEXT

• Track body weight, measurements, body composition, and progress photos
• Review strength, nutrition, calorie balance, and body-weight trends
• Connect training, food, activity, and progress instead of reviewing each in isolation

MAKE IRON YOUR COACH

Iron is built into Cipher, so you do not have to copy your fitness history into every conversation.

Use Iron to:

• Review recent workouts and plan the next session
• Log workouts, meals, weight, and activities
• Explain nutrition targets and progress signals
• Remember relevant goals, preferences, constraints, and corrections
• Send configurable workout, nutrition, recovery, and weekly check-ins
• Match the communication style and coaching approach you prefer
