## What is SMS Filter?

Stop being distracted with spam, junk or other unwanted text messages, including SMS and MMS.
With SMS Filter, you now at last have a control of incoming text messages.

Features:
 - create your own list of rules to filter your incoming text messages
 - filter incoming text messages by text patterns, keywords, or regexp
 - blacklist or whitelist messages that match particular rule
 - test your rules on test message

Pro feature:

Spam Protection subscription.
Stay protected from massive spam attacks, let you messages be checked with our spammer database - for only $2.99 yearly (price varies by country).

Spam Protection works following way:
- when several users receive the same SMS from same sender during short period of time - that looks like a massive spam mailing. Once we detect that mailing, we treat next messages from that sender as a spam, and sender - as spammer.
- once sender is marked as spammer, new messages from this sender to subscribers are filtered. A list of such senders is our spammer database.
- once message is marked as spam, we use statistical algorithms to analyze text in it. In case new SMS message is sent from unknown phone number to subscriber, and it is similar to known spam messages, we filter it either.

### 4/5 — great app, but subscription doesn't work

*2024-03-13*

great app and all, very small size, and i've not had a problem with it. only problem is that when you start the subscription for spam protection, the app claims to have failed to verify the apple store receipt. however the free functionality of the app works.

### 1/5 — SCAM ???

*2023-06-05*

I paid for this and it still offers a free trial or option to purchase. So the question is, is this working or not? Tried to contact the seller but no luck. Email says returned due to overflowing. 

Beware!
