ZaWorld vs Roundwork

[Concept] Byouyomi – Limit Break Timer is a count-up timer designed for 30 seconds of all-out physical effort. Its true value lies in the final 10 seconds—when things get toughest. • Just like in a 30-second Shogi match, the app counts aloud “1, 2, 3…” to build tension and sharpen your focus. • When you’re nearing your limit, shout “The World!” and time will stop. Break your limits with your own voice. That’s what this timer is all about. Perfect for core training, multi-ball table tennis drills, planks, and other high-intensity workouts. Visuals, voice, and tension—experience a new kind of countdown timer designed to push you beyond your limits. [Features] ● Tap the screen to begin. A 3-second countdown is followed by a 30-second count-up. 　- Audio cues signal the countdown and the start. 　- Time is displayed with numbers and a visual gauge. ● The app uses Shogi-style voice countdown—with a rising count from 1. 　- Audio cues at 10 and 20 seconds 　- After 20 seconds, it counts aloud every second from 1 to 9 ● After 20 seconds, shout “The World!” to stop time. 　- Microphone and speech recognition permissions are required 　- During time stop, the display and voice effects change dramatically ● At the end of 30 seconds, you’ll hear an audio cue. 　- If time stop is active when you reach 30 seconds, a special sound plays to boost your motivation.
