WHY REP-ON
Memory cannot beat records.
But records alone are not enough.
Most tracking apps save your past workouts and turn them into charts. Deciding how to change the next weight or where to move a missed session is still up to you. REP-ON carries your records through to the decision.
WHEN AI BECOMES NECESSARY
When the plan breaks,
AI becomes essential.
What matters is not a one-off recommendation, but a next choice that changes every time your records do.

FAQ
Before you begin.
Where does expert design and review show up?
An active trainer designed and reviewed routine structure, weight and rep adjustments, exercise alternatives, and the pain-input flow.
How is this different from a workout tracker?
REP-ON goes beyond records and charts. It reads completed sets, missed targets, pain, unavailable equipment, and remaining training days to suggest the weight, reps, exercise, and schedule to change next.
Does AI make every workout decision for me?
No. REP-ON recommends routines within safety conditions such as pain, equipment, and training experience. You always make the final choice.
Will AI keep interrupting me during a workout?
No. The workout screen stays focused on the set in front of you. Analysis and explanations are shown after the workout.
What if equipment is unavailable or something hurts?
REP-ON uses the unavailable equipment and area of discomfort to suggest an alternative that preserves the purpose of the workout.
