The most powerful SMS blocker on iOS. Automatic filtering using artificial intelligence, customizable lists supporting powerful regular expressions and more!

Junkman is the most powerful SMS filtering app for iOS 15 or later. It can classify incoming messages as normal, junk, transaction or promotion. It will not classify old messages. It works completely locally on your device without the need for any network connectivity.

Junkman primarily uses a state-of-the-art machine learning algorithm called Smart Filter, that is trained with thousands of messages in English and Turkish languages. This results in an artificial intelligence which can detect the language of a message and then check and classify the message contents. The Smart Filter can differentiate between normal (conversations etc.), transaction (bank OTP messages, shipping information, doctor appointments, etc.) and junk (promotional, gambling, unsolicited, spam etc.) messages instantly. It treats all promotion messages as junk.

Junkman also has a special algorithm called Aggressive Filter to detect and filter the most invasive junk messages without the need for the Smart Filter.

In case you would like to override the classification of the Smart Filter or the Aggressive Filter, you can add rules to one of the Safe, Junk, Transaction and Promotion lists in the app.

If you don't receive English or Turkish messages, and you only receive messages in other languages, you can disable the Smart Filter completely and manage messages using the rule lists. Aggressive Filter will remain active in this case.

The rule lists let you write much more powerful rules than most of the competing apps. They can work on both the sender or the content of a message and they accept any input including regular expressions (Regex). They are also simpler to manage than other apps.

If you think the Smart Filter did not classify one or more messages correctly, you can report them from the Messages app (iPhone only) for review. The more wrong classifications you report, the better the Smart Filter gets!
