User Reviews

Users praise whowho for accurate caller ID and effective spam blocking with useful features. Major complaints repeated across reviews: intrusive ads, extensive permission/data-collection requests, stability and performance issues (crashes, slow/startup, battery use), and overlay behavior that interferes with calls and other apps.
Pros
  • Effectively detects and blocks spam/scam calls (fast automatic blocking reported).
  • Provides useful caller identification and informative details for unknown numbers.
  • Has multiple helpful features for managing calls and messages (users find it useful overall).
Cons
  • Intrusive and frequent ads, including pop-ups and ads shown 'on top' of other apps.
  • Asks for many permissions and raises privacy/data-collection concerns.
  • Stability and performance problems: crashes, freezes, slow startup, battery drain, and background processes.
  • Overlay/pop-up behavior interferes with calls and other apps (prevents closing screens, blocks navigation UI, can stop call recording).

좋은 앱 감사합니다! 다만 노티스토리를 위젯으로도 만들어서 바로 확인 가능할 수 있게 해주시면 더 좋을거 같아요 🙏🥺

25년 3월) 전화앱 대체해서 쓰고 싶은데, 초기 실행이 너무 오래 걸린다..... 좋아진줄 알았는데 광고가 진짜 너무 많다. 삭제 (s23 ultra)

백그라운드에서 계속 작동하고, 끌 수 없으며, 광고가 너무 많습니다. 이 앱이 직장에서 필수라서 삭제하지 못하고 있습니다.
