RoundBoss Interval Timer
Other timers make you scroll through menus, tap through screens, and waste time before you even start training. RoundBoss is different. Hold the button, say "5 rounds, 3 minutes, 1 minute rest" — and your session is ready before you finish your sentence. Nothing is faster.
INTERVAL TIMING IN UNDER ONE SECOND
Hold. Speak. Train. That's it. AI parses your voice in real time and builds your interval timer instantly. No menus. No scrolling. No typing. Just say what you want and go. From voice to timer in under a second — every single time.
ZERO-FRICTION SETUP
Say anything natural: "Boxing 12 rounds," "Tabata 8 rounds 20 seconds on 10 off," "Quick 3 round warmup." The AI understands it all. Review your config, tap start, and you're training. The fastest path from idea to interval.
PRECISION TIMER ENGINE
Once you're in, the timer is relentless. Timestamp-based accuracy with distinct audio cues for every phase — prep, round, warning, and rest. Circular progress ring, round indicators, haptic feedback on every transition, and keep-screen-awake so you never break focus.
17 SOUND THEMES & VOICE COACHES
Classic boxing bells. Cinematic war drums. Zen garden chimes. Arcade bleeps. Motivational voice coaches who push you through every round. 17 themes, each with 12 unique audio clips and its own personality.
SPOTIFY-STYLE TEMPLATE LIBRARY
Browse presets for Boxing, MMA, HIIT, Tabata, Muay Thai, and more. Save your own custom templates. One tap to launch any workout you've built before — because the fastest timer should also have the fastest recall.
10 VISUAL THEMES
Neon lime Boss Mode. Crimson Heat. Deep Ocean. Ice Storm. Zen Trainer. Each theme transforms the entire app — colors, surfaces, accents — across every screen.
