## What is 1Round?

1Round is the training timer built for athletes who don't settle for basic.

Whether you're hitting the heavy bag, grinding through HIIT intervals, or pushing through MMA rounds — 1Round keeps precise time so you can stay locked in.

BUILT FOR YOUR SPORT
Five professional presets ready out of the box:
• Boxing — 12 × 3-minute rounds, 1-minute rest, 10-second warning
• MMA — 5 × 5-minute rounds, championship format
• HIIT — 8 rounds of 40-second work, 20-second rest
• Tabata — classic 8-round 20/10 protocol
• Custom — your starting point for anything else

EVERY DETAIL CONFIGURABLE
Set round duration, rest duration, and a warning countdown from the main screen. Need different durations for different rounds? Per-round variable timing has you covered.

SOUNDS THAT MEAN SOMETHING
Five independent sound cues — round start, final round, warning, rest start, and finish — each configurable separately. Choose from bells, warning tones, classic boxing bell, and digital beep.

LIVE ACTIVITY & DYNAMIC ISLAND
Your workout lives on your lock screen and in the Dynamic Island while you train. See the current phase, time remaining, and round count without unlocking your phone.

LOCK SCREEN WIDGET
Glance at your round and time remaining directly from the lock screen at any time.
