SMS Filter‪+‬ 4+

I’ve been using this app for close to a year and it does exactly what it says it does, and it does it well. It can block spam texts from both phone numbers and email addresses because the filters are completely custom & can be set to check both the sender and message content, just the message content, or just the sender. The keyword matching is much more robust if you understand how regex works, so you should consider googling a tutorial/cheat sheet if you don’t know what that is (you're not forced to use regex, but it lets you make more complex filters so it’s worth trying to learn it). I highly recommend this app.

So far this app seems to be working great and is is exactly what I was looking for to filter SMS messages based on individual keywords or more complicated regular expressions, which are great for power users. Two things that could make this app even better: iCloud support to sync rules between devices and the ability to name/describe each filter so they don’t only appear as complicated regular expressions and you can tell what each one does.

I’d been thinking about some sort of regex based message filter the likes of this app for a long time, I had no idea it already existed!

Thanks so much for solving one of my longest time problems- my phone number having been assigned to me with thousands of spam senders already having ahold of it, being able to write short matches or regexes has made being anything but do not disturb possible again.
