THE APP DOESNT FIND THE ALREADY CONNECTED BLUETOOTH DEVICE IT DOES NOT WORK ITS A SCAM DO NOT BUY THIS. ### 1/5 — Doesn’t work save your money! *2023-09-16, version 1.0* No sound ### 1/5 — Complete Garbage *2022-11-22, version 1.0* Just don’t burden yourself with this app. If I could rate 0 stars I would. ### 2/5 — Volume *2022-11-07, version 1.0* Works for most part but volume goes up and down by itself ### 2/5 — volume issues *2022-06-25, version 1.0* I was able to connect and play everything without any issues but out of nowhere the sound will just go down and it's so annoying ### 1/5 — Does not play music! *2022-06-16, version 1.0* $50 for not being able to play my music? Can only a play my apple bought music which I have one song, I bought this so I could use it with Spotify and YouTube not this. Very disappointed. ### 1/5 — Trash *2022-04-23, version 1.0* Dog water app ### 5/5 — Strange but amazing once you figure it out *2021-12-02, version 1.0* So I have never had a transmitter like this and when I lost my old one I saw this at autozone the next day, usually I would pay $25 tops for a transmitter but this one said it was higher tech so I bit the bullet and bought it. I had the exact same issue as everyone else where I couldn’t play any music or anything, but I figured out how to connect, with iPhone at the very least, i could connect to the device through the app but not my settings, it wouldn’t show up at all, I unplugged the transmitter, shut off my Bluetooth, everything I could but it wasn’t until I unplugged it and turned off Bluetooth at the same time that it finally popped up on my Bluetooth screen, overall despite the issues with connecting to it I am still giving this five stars, changing the frequency by app on your dashboard is way nicer than reaching for the transmitter and remembering what buttons to push to put it in that mode, once I got connected it had better audio quality than ones I have used previously and being able to connect as soon as I get into my car without doing anything is nice. Great product, software can use some tweaking ## Frequently asked questions about smartSOUND ### What is the current rating for smartSOUND? smartSOUND has a rating of 1.9 stars based on 52 user ratings.
