지하주차장에서 차를 어디에 세웠는지 헤맨 적 있나요? CarTag는 주차하고 내리는 순간을 자동으로 감지해, 차 위치를 대신 기억해 드립니다. ■ 하차를 자동으로 감지 주행 후 걷기로 전환되는 순간을 모션으로 포착합니다. GPS가 약한 지하주차장에서도 동작하는 1차 신호예요. 감지되면 알림이 오고, 한 번 탭해 층·구역을 바로 기록할 수 있습니다. ■ 사진·메모로 정확하게 층과 구역만으로 헷갈린다면, 기둥 번호·통로·주변 모습을 사진으로 남겨 두세요. 한 주차에 사진 최대 3장과 메모를 함께 저장해, 돌아올 때 한눈에 찾을 수 있습니다. ■ 위젯에서 바로 확인 홈 화면과 잠금화면 위젯에서 마지막 주차 위치를 앱을 열지 않고도 확인할 수 있어요. ■ 직접 기록도 간단하게 자동 감지가 안 되는 상황에서도 걱정 없어요. 메인 화면에서 층·구역·사진을 직접 입력하거나, NFC 태그를 읽어 위치를 기록할 수 있습니다. ■ 테슬라 차량 연동 (선택) 테슬라 계정을 연동하면 배터리 상태를 확인하고, 경적·비상등으로 차를 더 쉽게 찾을 수 있습니다. 연동은 선택 사항이며, 연동하지 않아도 모든 기록 기능을 사용할 수 있어요. ■ 자동 감지에 대한 안내 백그라운드 위치 감지는 iOS가 방문을 확인하기까지 수 분이 걸릴 수 있고, 지하에서는 위치 정확도가 낮을 수 있습니다. 모션 기반 감지는 지하에서도 동작하며, 자동 감지가 안 될 때도 언제든 직접 기록할 수 있습니다. 주차하고 내리면, 나머지는 CarTag가. 이제 지하주차장에서 헤매지 마세요.
