개발자만만조원벌자

이런앱이 무료여서 너뮤 좋구요 다만 아이패드로 할때는 측정이 너무 잘되는데 핸드폰으로 할때는 측정이 잘 안되더라구요.. 그런 점은 개선해주시면 너무 좋을거같아요!! 친구들이랑 같이 공부도 할수있고 완전 짱!!!!!

다 좋은데

앉아서 폰해도 시간이 그냥 가요… 기준이 너무 느슨한듯….

인식이 잘 안돼요

인식이 잘만 되다가 어디 갔다 다시 오니까 인식이 잘 안되고 나갔다 들어왔다를 3~4번 해봤는데도 안 되고 각도를 바꿔봐서 해봤는데도 안됩니다. 다시 지웠다 깔아봐도 똑같습니다.

안녕하세요! 하마하마를 사용해주셔서 감사합니다! 당시에 인식에 오류가 있었던 것으로 확인하였습니다. 현재는 모두 복구된 상태입니다. 이제는 인식이 잘 될거에요! 리뷰 남겨주셔서 감사합니다. 앞으로 더 좋은 앱이 되도록 노력하겠습니다!

다시 복원해주세요ㅠㅠㅠ

공부시간 측정하면서 친구들이랑 그룹 만들어서 같이 할 수 있는 게 좋아서 쓰고있어요 그런데 업데이트 이후로 시간측정이 너무 쉽게 되는 것 같아요ㅜㅜ 어느순간 그냥 앉아있기만 해도 시간이 흘러가더라구요…

Response from developer

안녕하세요! 하마하마를 사용해주셔서 감사해요! 인식이 너무 어렵다는 문의가 많아, 공부 인식을 조금 쉽도록 변경하였어요. 그렇다고 너무 인식이 잘 되어버리면 정확한 공부 시간 측정이 될 수 없으니, 계속해서 업데이트해나가고 있습니다! 앞으로도 더 좋은 앱이 되도록 노력하겠습니다!

친구와 함께 할수잇는건 진짜로 좋은데 부족한 점이 좀 있어요

녹화할때 얼굴 공부책 이런게 보여야 타이머가 시작 된대서 다 해봣는데도 인식을 잘 안해줘요 차라리 그냥 인식 그런거 필요없이 타이머 녹화가 되면 좋겠어요

Response from developer

안녕하세요! 하마하마를 사용해주셔서 감사해요! 측정에 대한 문의가 많아, 오랫동안 수정 작업을 진행하였습니다. 이제는 인식이 잘 될거에요! 좋은 리뷰 남겨주셔서 감사합니다. 더 좋은 앱이 되도록 노력하겠습니다.
