Auto block the SPAM sms & stop the notifications, sound and vibrations for such SMS. The application uses Heuristic detection and Artificial Intelligence to automatically detect the unknown spam sms. It comes with its own database of around 5000 spam SMS messages which is utilized by the Heuristic detection engine to identify SPAM with high detection rates.The blocked SMS are placed inside “Unknown & Junk” section of the “Messages” application.

Blocked Words List : The application also comes with a Blocked list containing 600 known SPAM keywords. The application also scans the SMS against these known SPAM keywords to detect a SPAM SMS. This list could be further customized to add new keywords or modify existing ones.

Abuse Detection : The application is also designed to protect you from the SMS that contains abusive or offensive words. If any such SMS is received, these will automatically be blacklisted and all alerts will be silenced for them.

Blocked Numbers list : If you are getting continuous message from any particular person or service , please add them to the Blocked numbers list. Any SMS from such numbers will automatically be blacklisted by the application.

Allowed Words list : This list allows you to whitelist certain SMS types based on keywords such as OTP (One time passwords). To ignore sms containing certain words like OTP, please add those words to this list.

Block all Unknown SMS : When this option is turned on, the application will block SMS from any number that is not in your contacts. Please note that the application still does not need access to your contacts. The iOS APIs let the application know automatically if the received SMS is an unknown SMS. Your private data is always safe. This is an optional feature and it could be turned on if required.

Note :
a) SMS Spam Stopper is an extension. In order to enable this extension, please visit Settings - Messages - Unknown & Spam. On this page, please enable "Filter Unknown Senders" and "SMS Spam Stopper".

Very Useful App Developed By True Professionals

When I first downloaded this App I was disappointed because I could only remove the 600 blocked words that came with the App one at a time. I informed the Developer that removing these 600 words was too arduous for me. I wanted to populate the blocked word list for my own needs. In a matter of 2 days the Developer worked to revise the App to allow users to eliminate the predetermined 600 blocked word list in one step and create their own list from scratch. Users can still use the provided list and remove individual words if desired. So my 5 star rating recognizes both the usefulness of the App and the dedication the Developer has to it’s products and customers. I strongly recommend that anyone who is bothered by spam text messages use this App. Also check out other Apps offered by the Developer. Thank you for addressing my concern in a quick and professional manner.

Yes, it works great

After trying the application for a few days, I could happily say that the application is working great. It blocks spam and has various features like I could manually add the words that i would like to be blocked from a sms. For example : I was getting a spam sms that contained the word called “Job”. I added this word to the blocked word section of the application and the sms of that nature never troubled me again. Also most of the time the application intelligently auto detects and blocks the spam sms. The good thing about the application is you could “tune” it as per your needs using the features that it offers. And needles to say that it also have a good privacy policy. Overall this is a recommended application. I like it. You will like it too.

Just what I was looking for. Initially I was concerned my messages were being screened through their server but my understanding is tbis is not the case.
I don’t have a need for the pre-made block list they’ve put together since I’m using the option to block anyone not in my contact list. Not sure if this has any affect on local device performance, but none that I can tell. I do have to remind myself to check the new tab periodically, but getting rid of the annoying alerts for useless messages and robos was my goal and this works perfectly!
One request for the developer that’s probably simple: would it be possible to sort (or add an option to sort) the list of words I have allowed?

Low investment, high return.

Developer Response ,

Many thanks for your kind words. We are glad to know that the application is able to meet your needs. We will definitely add the option to sort the allowed words list in our upcoming releases.
