Junkman is the most powerful SMS filtering app for iOS. 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. It is written to filter all kinds of unwanted text messages, including betting, political, scam messages and company advertisements. Junkman primarily uses a state-of-the-art machine learning algorithm called Smart Filter, that is trained with thousands of messages in English, French and Turkish languages. This results in an artificial intelligence which can 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 spam and threat database with special filters 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 automated filters, you can add rules to one of the Allowed, Junk, Transaction and Promotion lists in the app. 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! Features of Junkman: • Smart Filter: A state-of-the-art machine learning algorithm that can classify any message in English or Turkish as normal, junk or transaction • Spam and Threat Database: A database that includes special filters which can be updated immediately using instant notifications when necessary • Proactive Filter: A special algorithm to directly filter the most invasive junk messages without the need for the Smart Filter • Rule lists, supporting any input, including powerful regular expressions (Regex) • Time schedules to customize filtering times • Under Attack Mode: A mode that can help with text message attacks • Reporting Extension support to report messages that you think were not classified correctly by the Smart Filter (iPhone only) • Configuration testing that lets you check any message to see the classification in real time • iCloud sync support for sender lists to sync information between your devices • Detailed VoiceOver design for better accessibility support • Dark mode support • Interoperability with Begone - Spam Call Blocker and Directory Junkman is the successor of SMS Checker app. ----- Junkman works completely locally on your device.
