한 문장이면 기록 끝. 쓸수록 나에게 맞춰지는 가계부. "어제 스타벅스 커피 오천원"처럼 채팅으로 쓰거나 말로 하면, 코그가 금액·날짜·카테고리를 알아서 나눠 기록합니다. 자주 쓰는 상호명과 카테고리, 입력 습관을 기억해서 쓸수록 더 빨라집니다. 모든 추천과 문장 해석은 아이폰 안에서 동작합니다. 소비 내역과 개인정보는 외부 서버로 보내지 않습니다. 광고도, 구독도 없습니다. [기록] • 채팅·음성 한 문장 입력 (Pro) • 지출·수입·저축을 따로 기록 — 적금·투자는 지출과 섞이지 않아요 • 무이자 할부 기록 (2~60개월, 회차별 자동 분할) • 자주 쓰는 내역 빠른 입력과 추천 • 반복 거래 자동 기록 — 월세·구독·급여를 규칙으로 등록 (Pro) [보기] • 달력으로 보는 하루하루의 소비와 수입 • 카테고리별 분석과 이전 달 비교 • 머니 플로우: 수입이 소비·저축·남은 돈으로 어떻게 흘렀는지 한 장의 차트로. 이미지로 저장·공유할 수 있고, 금액을 가리고 공유할 수도 있어요 • 메모·카테고리 검색 [편의·보안] • 홈 화면·잠금 화면 위젯 — 이번 달 현황, 머니 플로우, 빠른 입력, AI 입력 • 4자리 비밀번호와 Face ID·Touch ID 화면 잠금 • 월별 CSV(엑셀 호환)·PDF 리포트 내보내기 [CogBudget Pro] 한 번 구입하면 계속 쓰는 앱 내 구입입니다. 자동 갱신은 없고, 같은 Apple 계정에서 복원할 수 있어요. • 채팅·음성 입력 • 반복 거래 자동 기록 • 결제 방식 분류 (카드·현금·계좌이체) • 주 통화 변경 • 색상 테마와 기준 날짜(급여일 기준 한 달) • 앱 아이콘 색상 데이터 입력과 조회는 언제나 무료입니다.
