Needs improvements

I like your app a lot and I’m hoping to see some great updates in the near future. I’ve tried many different 3rd part light app and yours is the only one that can run my new Nanoleaf light bulbs. I’m using your beta HomeKit setting and it need a lot of work. It’s a good start and it does what I’m looking for. Just wish that this app could run in the background of my phone instead of having to be in the app and music syncing problems. Like I said I’m liking what I’m seeing. But for now this app will have to be at 2 stars for now. I’m hoping to give this a more than 2 stars and change my review. I really want give your app 5 stars if these huge / minor problems can be fixed.

App is very unresponsive.

Only two of my four light in the scene of the lights sync “properly” to the screen. I put it into quotations because whenever you enter the app in this state the app become very unresponsive and normally unresponsive, but it is a beta feature. Sync to music, sometimes work and other times it does not. Unfortunately I can not recommend this app.

Updated review

It connected to my Apple Music and to my Hue Bridge, but the music only plays out of the ear piece of my phone and the lights don’t do anything.

UPDATE: I ended up getting it to work, although I did encounter a bug. The lights will randomly dim and stop syncing to the music. I’ve found that either skipping the song or changing the volume down then back up will resolve it temporarily.
