I’m guessing app is no longer supported?? ### 1/5 — App is out of date and useless *2025-07-13, version 2.21.4* Really annoying that the app isn’t working anymore. I would give it a 0 but the software won’t let me. ### 1/5 — WORST SETUP *2025-07-02, version 2.21.4* This app is worthless. I downloaded the app, installed on my iPhone 15 Pro Max. Pressed the LINK button on my Guardian CDAP5500BCA Purifier. I literally set my phone on top of the purifier with the blue LINK light flashing. Nothing at first, but then I got repeated “looped” “unable to setup, verify device is connected to the internet” error messages. I stopped the app, ran a Speedtest.net test to verify I had connectivity. Solid internet access on my phone. Tried again with same looped error message. Nothing. Zilch. Nada. Uninstalled, reinstalled app with same results. Worthless. ### 1/5 — Removal off AppStore *2025-06-29, version 2.21.4* I suggest you remove the app if you are not going to update it because from the looks of it was not updated since since the iPhone 7 ### 1/5 — Cannot use app *2025-06-27, version 2.21.4* The app will not open. I keep getting an error message each time I attempt to open saying check network connection. I can’t even connect my purifier to WiFi or Bluetooth ### 1/5 — Don’t bother, unless you enjoy torture. *2025-06-27, version 2.21.4* I purchased two towers that you can connect to the app and control through Alexa/Google. After the filter was replaced in both machines, WITH Brand specific filter, I can’t get a green blinking light to stop, nor connect them to my account, or do ANYTHING! ### 1/5 — Won’t even connect to network *2025-06-24, version 2.21.4* The app itself won’t connect to my WiFi network on initial start up and set up, whether on 5.0ghz or 2.4ghz. Completely useless! ### 1/5 — Useless App *2025-06-06, version 2.21.4* The app used to work but not any longer. Cannot connect to local network. ### 1/5 — No longer supported *2025-05-12, version 2.21.4* It says it works for this device but it doesn’t work at all. It doesn’t recognize internet even if just using data. Still selling devices for $170 with no app support. This was verified by the company today 5/12/25. Shame!! ### 1/5 — Unusable *2025-05-11, version 2.21.4* No longer supported ## Frequently asked questions about Guardian TE ### What does the Guardian TE app do?
