## What is Defndr?

Defndr is an SMS firewall that stops spam before it reaches you.

On-device machine learning checks every message from unknown senders, blocks phishing and scams, and quietly sorts the rest into the right folder — without sending anything anywhere. Your messages never leave your iPhone.

### 5/5 — Unique Outstanding Design App!

*2025-04-15*

I have found that this Unique Outstanding Design App is a great access to protecting you myself and our Family! The Developer has taken a great deal of time hard work sweat and yes love into the coding of this software so that all of us can be confident that we are secure and safe! I want to thank the Developer for an outstanding 5 Star ⭐️ App. I truly appreciate your dedication and unique knowledge for creating this app! With that Mr. Developer I Tip my Hat 🎩 to you and say “Thanks “ for all of my friends who have taken the time to read this do yourself a favor and download this Unique Outstanding Design App! I don’t believe you will be disappointed! ( really ) !!! I Thank the Developer for His offer, but I can’t take Him up on the offer Why because this is a great Unique App and there are times when Apple does an update to Help us all but sometimes this doesn’t Help the Developer instead it can mess up His Software coding that suddenly needs to be corrected! Does this make the software or App Bad? Of course not and anyone who does not understand this should not make false statements! This App does not deserve a 1 Star Review it is Truly a Unique Outstanding Design App an App that is a 5 Star ⭐️ App and I again Tip my Hat 🎩 to the Developer and Say “ Thanks “

**Developer response:** Thank you for your kind words. The app is currently undergoing maintenance due to an issue with Apple message filter entitlements which is expected to be fixed in the coming days. Please send me an email and I’ll send you a free subscription code!

### 1/5 — Dark mode

*2025-04-12*

is an accessibility feature and should never be paywalled.

**Developer response:** This has been addressed in the next release which should be available for download by tomorrow. The reason for the delay is I had taken the app off the store whilst I tried to implement fixes for Apple’s consistent changing of the backend framework, I was focusing on those technical issues and as the app was not available for over one month I had not addressed the visual side of things. Please email me if you would like an annual premium code, and I would appreciate if you could re-review the app once version 2.2 is available.
