Some suggestions would be to color coat distance errors, ie circle turns red when too close and blue when too far. Right now red just means something is wrong. Another suggestion would be to have options for multiple photos and frames. Sometimes patients look away from the camera or tilt their head. Giving us multiple photos would let us use the best photo and allow for more frames. Right now I am creating multiple profiles for multiple frames. ### 1/5 — 기존 고객정보 일괄삭제하게 만들어줘요 *2025-06-04, version 2.8.1* 하나씩 지우는거 느리고 힘들어요 ### 4/5 — ipad11 ? *2025-05-05, version 2.7.0* update ### 1/5 — 어플을 사용하기 힘들정도로 팅겨요 *2024-12-19, version 2.4.2* 너무심각해요 ### 1/5 — Not working *2024-11-27* Worked fine with prev update on old iPad update.
