## What is Junkman?

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.

Rien est gratuit donc inutile..

*2026-06-10, version 15.0*

The Developer has coded this software so Unique that it truly helps you myself and our family. It’s a 5 Star ⭐️ app that puts the Junk text where it belongs in the Junk File. This app works for me and has since the day that I downloaded it. So if you’re taking the time to read this then Download this app and give it a try! Will you be disappointed? I believe in the long run you will not be. ( really ) the Developer has put a great deal of time hard work sweat and yes love into the coding of this software! How do you know? Look at the number of updates that have been made! There are crooks out there who want our money and identity if given to them the opportunity. The Developer has created an amazing Unique Outstanding Design App that puts Junk crooked mail where it belongs. Sometimes the Developer gets his hands tied by Apple. Why I can’t answer but that doesn’t mean this is a bad App it means the Developer is out there trying to code this software to get around the restrictions! So with that I want to Thank the Developer for putting out this Unique Outstanding Design App. I truly Tip my Hat 🎩 to you and say thanks. Mr. Developer I am proud to say you have truly created a 5 Star ⭐️ App. One that for this ole man you can truly take a bow 🙇‍♂️.

### 1/5 — Données traitées localement ou chez le développeur

*2026-06-09*

Lorsque vous installez l’application, elle dit que tout est traité localement
Lorsqu’on ouvre l’application après l’installation, l’application indique que les données seront transférées automatiquement au développeurs

Quelle est la bonne indication s’il vous plaît ?

### 5/5 — Works so well!

*2026-05-21, version 15.0*

This app works so well. It’s very rare that I get any spam texts.  This app stop almost all of them.

It did have some false positives but I used the custom filters to let through that content.

I highly recommend this.

### 2/5 — Doesn’t work

*2026-04-30, version 15.0*

I tried this with the Pro plan to filter out political spam texts. I was disappointed.
- It only works on the phone, but I have iMessage synced to my Mac, and still got all the messages there. 
- The “report spam” integration mostly did not work, with the name and number fields being blank.

### 2/5 — Not so great anymore

*2026-04-28, version 15.0*

I use to love this app and tell everyone to use it, now it’s not so great….actually it kinda sucks.  Daily spam coming it and lots of it. All the settings are as instructed(and having to check daily, well I should t have to keep checking over and over to see if my Junkman setting are set correctly, and yes I have rebooted a million times.  Time to find something else.

### 1/5 — Doesn’t Actually Block Anything

*2026-04-10*

If it doesn’t actually block spam messages, what good is it? If the sender doesn’t know they’re being "blocked", aka filtered, why would they even stop messaging? If Apple doesn’t let these apps actually block messages, what good are they? If spam is just moved to another location on my iPad by keyword and the sender doesn’t know it, what stops the sender from spamming me again and again? Makes Apple complicit in this message blocker app scam. I canceled my subscription immediately. The built-in "Delete message and report junk" already does that for free.

At least on my phone, the Number Shield app "answers" these calls by posting "stopped by Number Shield". All I have to do is access the missed calls screen and select BLOCK CALLER. I never get another call from that phone number. Does the sender know they’re being blocked? No idea. But I never get another call from that number ever again. 

I never set up voice mail on my phone so spammers don’t get to leave me a voice message. That’s good enough for me.

### 5/5 — Extremely effective & Works with iOS26 spam folder

*2026-04-07*

I’m very impressed with this app and it works much better than the built-in iOS 26 spam detection or Verizon Call Filter+. Neither of those would actually place messages into the spam folder most of the time. At best iOS spam blocker would put SPAM in promotions and it would still miss some spam.

After using this for about two months with the paid pro pack smart filter, it’s catching absolutely all spam and putting it into the spam folder where I never even have to see a count bubble.

### 1/5 — Tilki

*2026-04-04, version 14.7*

Güzel kurnazlıkmış yıllarca insanları kendine bağlayıp bir anda ücretsiz kullanıcıya her özelliği kapatıp herkesten para istemek. Stratejik olarak saygı duydum, müşteri olarak iğrendim.

### 5/5 — Political texts

*2026-03-20*

By making your own rules all political texts that come in your messaging app have about 32 different variations on the last line of their text and that makes it very easy (like "stop to end")  to make rules to eliminate all of them!

How long that I spent a couple years constantly trying to get rid of about 100 text a day!

Destroying my normal life just because I donated!
