Now, with the new update, it does not think the device is on even after a successful set up. I tried everything and wasted way too much time. Never using an app for a device like this again. ### 1/5 — It doesn’t work *2026-02-20* The app it doesn’t work at all. Why is on the App Store? I check the website and it doesn’t exist neither. ### 1/5 — Won’t allow me to register *2025-09-27* Accepted terms & policy but app keeps telling me I need to accept to register ### 1/5 — QR code scan does not work app has been downhill for last year *2025-02-11* Do not buy was amazing and last year has gone downhill, no longer can track over time, QR code doesn’t scan and these are expensive and only last two years ### 1/5 — Updates have ruined what was once great *2024-04-30* This used to be amazing app not only to control your devices and check when they need filter replacements, but also to check and track air quality. Unfortunately after many updates the app no longer accurately tracks air quality and it’s no longe user friendly ### 1/5 — App says check network connection *2024-03-21* Worked fine for a week, now it says check network connection. All other devices work in my house just not this app. Terrible app. ### 1/5 — Pointless *2023-09-05* Can’t add a device. Even though it goes through all the steps it doesn’t show up ### 1/5 — Wiped info clean with latest update *2022-07-20, version 2.0.0* On a downward spiral don’t waste your money app updates wipe out device and data, filters are hard to find ### 3/5 — Where’s the ring in the app *2022-03-17* I can’t find the colored ring with the air quality score in the app. ### 1/5 — No remote access - no app registration *2021-05-17* I cannot create a log in- not with phone and not with email. No confirmation code is sent. So this does not work— at least not for USA. Any other way to control via remote access? I was going to buy two more but now not so. ☹️ ## Frequently asked questions about Zigma ### What devices can Zigma control?
