I waste alot of time trying to teach customers the best way to use. You need to redesign this app asap ### 5/5 — Is easy *2023-03-15, version 1.10.3* Easy to operate ### 4/5 — App *2023-03-05, version 1.10.1* System works great! Having some issues with the new app. I was able to rename sources 1-6, but 7 - 12 won’t change? I have tried multiple times. They change in the settings and zone renaming, after applying save and go back to main screen, 7-12 still read zone 7-12 ### 5/5 — Big Improvement *2023-02-28, version 1.10.1* The new App works perfect with my WS66i and M66-EXT system , big improvement and the new GUI definitely much more easier to use, thanks Soundavo to make it happen, good job ### 2/5 — App needs upgrading *2023-02-05, version 1.9.0* The WS66i system has good power and sounds good. However the apps need to be reprogrammed . First issue is you need 2 apps to control this unit. I do not understand why. The app WS66i that power the zones does not auto refresh. The app closes and reopens that is very annoying. The other app soundova which controls the music source. That works ok, just needs a bit more tweaking. It is best to put both apps into one and fix the refresh. ### 5/5 — nice whole home system *2023-01-26, version 1.9.0* Purchased the WS66i amplifier system and follow the instructions video on YouTube, very easy to setup and the UI looks good, available to control the device for selecting input sources & zone, the built-in streamers and EQ is great function, we’re enjoying this system. ### 4/5 — Switch back to the new version! *2023-01-26, version 1.9.0* I really liked the new version and would like to see it come back! The new look version looked great and worked after I manually entered the IP address for my system. The auto IP find function was slow. Switch back to the new look version please! ### 1/5 — Updates app does not work! *2023-01-23, version 1.9.0* The Soundavo app updates today. No instructions on the new app and it wipes out everything from the old app. You must reprogram all your rooms and sources. Next the app will not connect to the amp. After many attempts I did get it to connect but it keeps disconnecting when the app is closed. Each time before you can use the app to run the system you must manually reconnect! 😡 ### 1/5 — ugh *2023-01-22, version 1.8.6* No, no, NO!! Very worse app I have ever owned. I installed this system in my home. It’s a little clumsy, difficult to learn and use, but after a year I finally had my family grudgingly using it. They just did an auto app update — 100% completely unusable. Do NOT ever buy this system or use this app. ## Frequently asked questions about WS66i ### What is WS66i used for?
