### 4/5 — 트레이닝 기록 다운로드 오류

*2026-06-26*

안녕하세요. 
co2 트레이닝 완료 후 다운로드를 누르면 사진이 저장되지 않고 앱이 종료됩니다. 
확인 부탁드립니다.

그리고 이전처럼 테이블도 함께 표시되면 기록을 한눈에 확인할 수 있어 더 보기 좋고 편리할 것 같습니다. 감사합니다.

### 3/5 — 애플워치 미지원

*2025-06-26*

경쟁앱(apnea trainer)은 애플워치를 통한 심박수 측정을 지원하는데, 왜 아직도 지원을 안해주실까요.
아쉽습니다.

**Developer response:** 안녕하세요! FreeDive Ai 운영자입니다. 아쉽게도 애플워치의 경우 다른 옥시미터 기기와 달리 실시간 심박수를 지속적으로 제공하지 않아 연동과정 중 제외하게 되었습니다. 저희 앱을 응원해주셔서 감사합니다. 좋은 하루 되세요!
