Tap one to edit it, swipe or long-press to delete it, or clear them all at once. Moving to a new phone Copy your whole history to the clipboard as text, then paste it into DaDa on the new device to restore it. Restoring replaces the data already there.

매 라운드가 쌓이면 실력이 돼요. 라운드제로는 복싱, 주짓수, 킥복싱처럼 라운드로 훈련하는 분들을 위한 타이머이자 운동 기록 앱이에요. ■ 라운드 타이머 라운드 시간, 휴식, 라운드 수만 정하면 바로 시작할 수 있어요. 끝나기 전에 소리와 진동으로 알려줘서 화면을 안 봐도 괜찮아요. 자주 쓰는 설정은 프리셋으로 저장해 두세요. ■ 루틴 몸풀기, 쉐도우, 미트, 샌드백까지 하나로 묶어 두면 끝날 때까지 알아서 이어져요. ■ 이번 주 목표 링 한 칸이 한 라운드예요. 하나씩 채우다 보면 목표가 금방이에요. 연속 운동 일수와 이번 주 순위도 함께 볼 수 있어요. ■ 운동 기록과 공유 하루, 한 주, 한 달 단위로 지난 기록을 넘겨 볼 수 있어요. 운동이 끝나면 예쁜 링 카드로 인스타 스토리에 바로 공유해 보세요. 그 밖에 다크 모드, 콤비네이션 커뮤니티, 내 주변 체육관 찾기도 있어요. 앞으로 다양한 기능을 추가할 예정입니다
