여행지에서 가격표를 만나는 순간, 2초 안에 원화를 아는 가장 빠른 방법. won-now 는 앱이 아니라 위젯이 주인공입니다. 홈 화면 위젯의 숫자 패드에 가격을 그대로 입력하면 — 앱을 열지 않고 — 즉시 원화로 보여줍니다. ◦ 위젯에서 끝나는 환산 홈 화면 위젯에 숫자 패드가 있습니다. 180 을 누르면 바로 "8,126원". ◦ 오프라인에서도 동작 하루 한 번 환율을 자동으로 받아 저장합니다. 로밍이 끊긴 지하 식당에서도 마지막 환율로 계속 계산하고, 얼마나 오래된 환율인지 배지로 정직하게 표시합니다. ◦ 설정은 여행 첫날 한 번 "어디로 여행 가세요?" — 나라 하나만 고르면 끝. 다음 여행지에선 바꾸기만 하면 위젯도 따라 바뀝니다. ◦ 30개 여행 통화 지원 태국 밧, 일본 엔, 베트남 동, 대만 달러, 미국 달러, 유로 등 여행객이 실제로 만나는 30개 통화. 환율 출처: Rates by Exchange Rate API (exchangerate-api.com), 하루 1회 갱신.

Verdict
The clearest difference is ads: 환율계산기(위젯) at none against Tap Exchange's shown. 환율계산기(위젯) also leads on update cadence (every 2 days vs every 10 days). Tap Exchange's advantage is iOS requirement (13.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
