## Description

Call Blocker is a powerful Chrome extension designed to manage and block unwanted incoming and outgoing calls efficiently. It features the fastest algorithm for call blocking and allows users to customize how calls are handled — reject them, silence, or play a 'number unavailable' message. The app operates with minimal resource consumption and provides an intuitive interface with blacklist and whitelist management. Users can add numbers manually, from contacts, call history, or messages and organize them into groups for scheduled blocking. Logs track blocked calls, with options to export or disable notifications for privacy. Additional features include blocking calls from unknown or hidden numbers and password protection to safeguard user settings. Call Blocker offers comprehensive call control ensuring a peaceful phone experience.

## Review summary

Users generally praise Call Blocker for its simplicity and ability to block unwanted calls without needing to set it as the default dialer. The app is described as easy to use and effective at blocking spam numbers. However, multiple reviews report reliability problems: blocking can fail or let calls through, outgoing blocking may not always work, and some devices experience crashes or force closes. Some users also note difficulty in becoming the default app on certain devices. Overall, strong usability and blocking capability are offset by stability and reliability concerns.

### Pros

- Easy to use / simple UI
- Blocks unwanted calls / spam numbers
- Does not require making it the default phone app
- Unobtrusive / non-intrusive experience (no forced default or intrusive prompts)

### Cons

- Blocking is unreliable: calls can be blocked inconsistently or not intercepted
- Outgoing call blocking not working in some cases
- Cannot easily become the default phone app on all devices
- Crashes or force closes on some devices (stability issues)
