The popping noise can‘t be solved for a long time! Developer abandoning updates :(

The noise is so loud that the app cannot be used properly. Using this app will likely ruin the iPhone's speaker soon. Has the developer given up on bug fixes or updates? Even after sending emails, there's no response or debugging. This app is currently causing crashes by attempting to bypass iOS's standard sound output system, which changed long ago, and directly control the device hardware (low-level audio). This occurs because the iPhone's high-performance microphone/speaker drivers are incompatible with the app's outdated audio engine, making it a compatibility flaw inherent to this old-fashioned app itself. Please update it. Or remove in-app purchase. 잡음이 너무 커서 앱을 정상적으로 사용할 수 없습니다. 이 앱 사용하다가는 아이폰 스피커 곧 망가질듯. 개발자가 버그 수정이나 업데이트를 포기한 건가요? 이메일 보내봐도 답변도 디버깅도 없네요. 이 앱은 오래 전에 바뀐 iOS의 표준 사운드 출력 시스템을 완전히 무시하고 기기 하드웨어를 직접 제어(low-level Audio)하려다 충돌을 일으키는 상태입니다. 아이폰 고성능 마이크/스피커 드라이버와 해당 앱의 구형 오디오 엔진이 서로 맞지 않아 발생하는 현상으로, 이 오래된 앱 자체의 호환성 결함입니다. 제발 업데이트 좀 하시길. 인앱 결제를 없애든지.

Used to love it,hate the change, update

I’ve used Violin Pitch, to help me develop an ear. I really dislike the new green dots instead of green line to indicate where the sound is , high, low, right on etc. hope you will change that back. Update, thanks so much for going back to the green arrow and for fixing the tuning. I tune to 440 and it was no longer correct but is now!! Back to loving and using this app

Why did you change it?

I’ve used this for years, primarily to double check my intonation. I HATE the new little green dots. Not only are they hard to see but it’s unclear where the dots will show up. Bring back the green arrows and lines! I am really dissatisfied with the change.
