낚시성 앱


이름만 pro고 사실은 lite.
광고가 하고싶었으면 앱 이름에 프로를 넣지를 말아야지.
그래놓고 리뷰 답변으로 '무료라는 사실에 의해 보상됩니다' 이런소리나 함
무료로 광고 볼 생각 없었는데, 시간버리고 기분나쁘고 개발자 마인드가 글러먹은 앱.
다운받지말기를 추천함. 이미 다운받았다면 다른사람들을 위해서 별점 1점이라도 주고 가시길..

Developer Response

프로라길래 기간한정 무료 이런건줄 알았더만 앱 이름이 프로네
이름으로 한번 낚고 광고 빈도수에 놀라고

앱의 이와 같은 기능 제한은 무료라는 사실에 의해 보상됩니다. 다른 조건으로 다운로드가 가능한 광고가 없는 애플리케이션의 포트폴리오를 확인하시기 바랍니다.
