Mark-1 is a workout journal for iPhone that keeps your sets, weights and training notes together. Write in your own shorthand or follow a saved routine.
WRITE YOUR WORKOUT
Type “bench press 185x8,8,7” to record three sets. Mark-1 recognizes supported exercise names, weights and reps and organizes them into your training history. Add a note about how a set felt without leaving your workout.
REMEMBER YOUR LAST LIFT
Look back at previous weights and reps. Explore exercise history, personal records and progress charts, so you have something concrete to refer to for your next session.
FOLLOW A ROUTINE
Create unlimited routines for free. Check off completed sets, adjust weights and reps, and reorder exercises to match your session.
KEEP YOUR TRAINING TOGETHER
Browse past workouts on the calendar. Correct an entry or add a workout you missed. Export your performed lift history as a CSV.
MAKE IT YOURS
Choose sage, rose or lavender, with light, dark and system modes.
MARK-1 PREMIUM (OPTIONAL)
Core logging, routines, history and charts stay free. Mark-1 Premium is an optional auto-renewable subscription ($4.99 per month in the US) that adds training plans built around your schedule and Insights on your lifts. Coaching is in a limited early rollout and is not included for new subscribers yet.
Payment is charged to your Apple ID account at confirmation of purchase. The subscription renews automatically each month unless cancelled at least 24 hours before the end of the current period. Manage or cancel anytime in your App Store account settings.
