What's New in RoundFlow
1.8
September 29, 2026
Rounds that aren't one flat block. • Intervals inside a round — 30 on, 15 off, repeated, with the bell still marking the round. The most-asked-for thing in this category, and almost nothing does it. • A longer rest every few rounds, so round 6 isn't the same as round 1. • Hands free — pause by holding a glove over the phone, or ask Siri. No touching a screen with wraps on. • Start from Control Center or the Action button. One press, at the bag. • A monthly challenge on Home, counted from your own training log. • Coaches: print an A4 poster with your gym's name on it, from Settings. The timer, the bell, your punch count and your log stay free. Forever.
