Dee / Reaction Rounds
iPhone · iPad · AndroidA pad holder in your ears. Dee calls the combination. You throw it, reset, and get ready for the next.
Reaction Rounds is available in Dee 1.0.17 on iPhone, iPad and Android.

Spoken moves and combinations give solo shadowboxing a clear next instruction. Find some space to move. No bag or equipment needed.
Choose Relaxed, Steady or Brisk, then change the space between calls during your round. Follow each combination once and return to guard.
Saved rounds join workout history and count towards weekly training goals and Fight Camp. An impromptu practice becomes part of the same habit.

0:20–0:28: A still capture shows Hebrew, right to left, at the largest accessibility text size on Duo in Book posture. The Hebrew coaching sample says ג׳אב, קרוס — “Jab, cross”.
