We built this app because every other "boxing timer" we tried was either ugly, full of ads, or stopped ringing the bell when the screen locked. We're indie fighters who care about the craft. The app is hand-coded in 15 languages, hand-tuned for accuracy down to the millisecond, and zero ads โ€” ever. If a round runs long because we shipped a bug, we want to know.
