Trox is a routine-based weight-training tracker for lifters who care about progressive overload.

■ POST-SESSION SUMMARY
• Automatic Personal Record (PR) detection on session end

■ STATISTICS THAT MEAN SOMETHING
• Per-routine session-volume line charts — tap a point to jump to that session's detail
• Per-exercise progression sparklines
• Weekly volume vs last week
• All-time Personal Records sorted by recency, best estimated 1RM, or alphabetical
