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).
