This app is designed to identify and analyze the patterns of everyday vibrations that surround us in our daily lives. Whether it is industrial vibrations encountered in the field, laboratory equipment noise, household appliances with motors, footsteps, or the output from audio subwoofers—this tool was created to help you easily monitor the magnitude, trends, and characteristics of these vibrations. - Technical Details & Disclaimers Sensor Dependency: The vibration graphs displayed are based on the specifications of the accelerometer built into your smartphone. Therefore, graph displays may vary slightly depending on your device's hardware performance. Professional Use: If you require strictly precise or calibrated vibration data, please use professional-grade vibration measurement equipment. Data Output: Vibration data values are not output as raw numerical figures. Privacy & Data Handling: Data measured by this app is not collected externally; all processing is performed locally on the user's iPhone. 본 앱은 우리 주변 일상 속에 늘 존재하는 생활 진동의 패턴을 파악하고 분석하기 위해 제작되었습니다. 산업 현장에서 접하게 되는 진동부터 실험실 장비의 노이즈, 모터가 장착된 가전제품, 발자국 소리, 그리고 오디오 서브우퍼의 출력까지—이러한 다양한 진동의 크기와 경향성, 특성을 본 도구를 통해 손쉽게 모니터링할 수 있습니다. - 기술 세부 사항 및 유의 사항 센서 의존성: 표시되는 진동 그래프는 스마트폰에 내장된 가속도 센서의 사양에 기반하므로, 기기의 하드웨어 성능에 따라 그래프 표시가 약간씩 차이가 있을 수 있습니다. 전문적 용도: 엄밀하고 정확한 교정 데이터가 필요한 경우, 별도의 전문 진동 계측 장비를 사용하시기 바랍니다. 데이터 출력: 진동 데이터 값은 별도의 수치 형태로 출력되지 않습니다. 개인정보 및 데이터 처리: 본 앱으로 계측된 데이터는 외부로 수집되지 않으며, 모든 데이터 처리는 사용자의 iPhone 내에서만 로컬로 이루어집니다.
