User Reviews

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.

Does not work and instructions are in Chinese

Almost completely incomprehensible UX. No instructions anywhere. Why not have a new option in individual spam messages to send the number to the blacklist? No way to do this without manually and awkwardly copy pasting the number into the app. Ridiculous. What a letdown and waste of money.

Works great. You must enable ‘Filter Unknown Senders’ and add numbers you trust to your contacts. I use it to block incessant political campaign spam texts.
