Sifter - Spam SMS Filter

Works great. You must enable ‘Filter Unknown Senders’ and add numbers you trust to your contacts. I use it to block incessant political campaign spam texts.

So far, I have tried to give it words to blacklist and when I have had people try texting me using those words the text still comes through. So either it isn’t working, or it isn’t user-friendly enough for me to be able to figure out how it works when it looks like I am doing everything right.

One of, if not the only app in the App Store allowing you to block those annoying, repetitive, unsolicited texts that are sent with click-bait links in hopes you’ll access a Trojan horse or other nefarious link. The “regex” area is a bit difficult if you don’t understand regex, but there are still several other ways to block these texts in bulk, the easiest being by copy and pasting +the+text+you+want+to+block in ⬅️ this format. Then all texts sent after that fit that format will be automatically blocked.
