SMS Shield is a Machine Learning-based SMS spam filter for iPhone. We trained it on what spam SMS looks like by showing it tens of thousands of spam SMSs beforehand. SMS Shield then learns and, to a high degree of confidence, can identify spam even it haven't seen it before. Besides spam blocking, SMS Shield includes innovative features like Frequent Traveler Mode.


+ Automatic Spam Filtering

SMS Shield will automatically block SMS spam like promotions, ads, phishing and scam attempts at stealing your sensitive information (e.g. SMSs claiming to be from your bank).

+ Frequent Traveler Mode

Enable this innovative feature during your business travels to block the often-annoying SMSs sent by mobile operators when visiting other countries (e.g. "Welcome to country X...").

+ Custom Block List

With custom block list, you can block SMSes from specific phone numbers or that include specific keywords. Remember that annoying Ex who keeps SMSing you years later? Blocked!

+ 100% privacy guarenteed

SMS Shield is an offline SMS filter. Meaning it does the filtering offline, on your device. All your texts are 100% private.

+ Multi-lingual spam detection

SMS Shield detects spam (and is localized) in English, Portuguese (Brazil), Italian, Swedish, and Arabic.

If you would like us to add a specific language email us with spam texts you receive (as many as possible).

Money suckers

This app is good but owner is freaking greedy since he did not say anything about subscriptions plan before downloading. It will be better if they charge one time app purchase, instead of hidden subscriptions. If you’re planning not to subscribe; it is worthless to download this app

Doesn’t work

I pay for the premium service but it doesn’t work anymore. I get daily spam texts that should be blocked based on the keyword, but aren’t. I can’t even contact them in any way other than this review, to which they may or may not choose to respond. Oh well, guess I’ll have to cancel and try another blocking service that doesn’t charge money...can’t get any worse.

No longer working

App worked flawlessly for a year or two, but after updating the iOS software on my phone neither filtered or unknown numbers are sorted anymore. I’m not sure if it is an iOS issue or a SMS Shield issue, but I’d love to get it figured out.
