## Review summary

Reviews are mixed. A common issue is unreliable spam blocking, with messages getting through despite keywords. Users cite a confusing UX and vague or absent instructions, including language inconsistencies. Some find it workable when configured (Filter Unknown Senders and trusted numbers) and appreciate bulk blocking via copy-paste. A minority view it as one of the few tools for link-based spam blocking. Overall, dissatisfaction centers on poor usability and questionable effectiveness for many users.

### Pros

- Blocks certain spam texts, especially those with links, when configured.
- Supports bulk blocking by copying and pasting text to block.
- Appears to work for some users when properly configured (enable Filter Unknown Senders and add trusted numbers).

### Cons

- Spam blocking is unreliable for many users; messages slip through despite keywords or blacklist entries.
- User experience is confusing and instructions are lacking or hard to follow (some content appears in Chinese).
- Blocking terms/numbers often requires awkward manual copy-paste steps and isn’t intuitive to use.
- Several users feel the app offers poor value for money and is not worth the price.
