About CalloutTimer
Master Your Rhythm. Visualize Your Progress. Callout is not just a round timer; it is your intelligent corner coach. Designed for boxing, MMA, and HIIT enthusiasts who demand more than just a beep. CORE PHILOSOPHY "Use your own voice to drive your action." Record your own technical cues—"Jab," "Head Movement," "Sprint"—and let Callout's intelligent engine direct your workout based on your custom strategies. KEY FEATURES Professional Round Timer Fully customizable rounds, work duration, and rest periods. Features a "Preparation" phase to get you ready before the bell rings. Perfect for Boxing, Muay Thai, Kickboxing, and Tabata. Voice-Driven Cues Forget robotic voices. Record your own commands. Configure playback strategies for different training phases (e.g., low frequency for warm-ups, high frequency for final sprints). Smart Video Review Automatically records your sparring or shadowboxing sessions. Timeline Markers: Instantly jump to specific moments where cues were played. No "Dead Air": Auto-pauses recording during breaks to save space. Immersive Replay: Full-screen analysis with frame-by-frame seeking. Privacy First & 100% Offline Your training footage is personal. Callout works completely offline. No accounts, no cloud uploads, no tracking. Your data stays on your device, always. WHY CALLOUT?
