### 3/5 — Works okay, instructions are confusing

*2026-07-16, version 2.2.1*

This app is good for a free app, but it could be more user friendly. For example , when you select the Blacklisting toggle, the words “Whitelisting” appear (because it’s on the other side of the toggle). For the longest time I was adding rules to the wrong place because it wasn’t clear which area I was in. 

The tutorial only tells you how to enable SpamHound on your phone, not how to use it. The FAQ section was written for those already familiar with the program. And some of its rule command are techie in nature. 

Right now I’m getting a persistent spammer coming and my blacklist time isn’t working. When I run the check, it shows it’s allowing the sender not stopping it. I can’t figure out why.

### 1/5 — Doesn’t work

*2026-04-24, version 2.2.1*

I did the test and everything and thought it worked but I’m still getting spam messages.

### 5/5 — Perfect app

*2026-03-21, version 2.2.1*

Somehow, I got on the mailing list of every senator and Congress person candidate. Few choice words and almost all of their SMS text messages (that I never signed up for) have disappeared. Great app. Thank you.

### 1/5 — It just doesn’t work

*2026-03-02, version 2.2.1*

Unnecessarily difficult to use and doesn’t work at all

### 2/5 — Seems unable to adall the new system

*2026-01-29, version 2.2.1*

This is an imperfect but excellent app that has been incredibly useful since I started using it. It filters almost everything I don't want to see and is customizable. However, since my recent upgrade to iOS 26.2, it seems incompatible with the new system. Apple has added a built-in filter, but it's difficult to use compared to SpamHound. And regardless of whether it's enabled in settings, it doesn't replace SpamHound (SH). Therefore, I think this app, which hasn't been updated in four years, probably needs an update. iOS 26.2 is very unusable, and I hope to revert to the older version if possible. I've been using SpamHound ever since. I'll revise my review after an update.

### 2/5 — Has it stopped working?

*2025-12-31, version 2.2.1*

Messages with words on the blacklist still get through.

### 5/5 — Review

*2025-10-18, version 2.2.1*

It’s a great app!

### 1/5 — Spam

*2025-10-11, version 2.2.1*

I’ve created rules, which when a text is verified against them, returns spam sms yet they still are delivered.

### 4/5 — Does block SMS, unfortunately not iMessages

*2025-08-28, version 2.2.1*

I tried blocking all messages from email addresses - they still go through. I also added a pattern “+63” but still getting spam from there. I heard that it is because those are iMessages and not SMS, and a lot of spam goes through iMessages, unfortunately.

### 1/5 — It does not work

*2025-08-25, version 2.2.1*

For some reason the app misses a lot of rules
