Mochi Jikan (もち時間) is a round timer designed specifically for Kendo practitioners and boxing coaches. It delivers precise phase timing with Japanese voice cues, color-coded backgrounds that signal each phase at a glance, and support for Bluetooth camera remote shutter triggers.

Built for the dojo and the gym, the interface disappears the moment a round starts — nothing on screen but the time and the current phase color.
