Rebuilt from the ground up. A new sample-accurate audio engine that never drifts, an all-new look, a faster start (no sign-in — ever), corrected 2:1 putting tempos, a redesigned Apple Watch app that keeps playing when your wrist drops, two-way iPhone↔Watch sync, and Siri ("start driver smooth in SwingBeats"). Plus SwingBeats+: custom tempos and practice streaks, one purchase, yours forever.
