What's New in 1.5.52
This update is all about reliability.
Rebuilt the active workout tracker with more dependable rest timers, draft saving, and finish/discard handling — an interrupted workout is far less likely to lose your data.
Fixed PR (personal record) celebrations that had stopped firing for some workouts.
Fixed a bug that could corrupt a PR when swapping an exercise mid-session. Affected PRs have been backfilled and corrected.
