Hasn’t worked in years
I have a Bluetooth device and i haven’t been able to change its settings for a while. So fully non-functional app
firmware update doesn't work
Just got EH11 headphones and attempted to update the firmware. Firmware downloads, but then gets stuck on "preparing: 0%." I tried downloading the firmware on my desktop and moving it over to my phone using iCloud Drive, but still it gets stuck on "preparing: 0%." no other info, no help or in-app support. Nothing online. Useless app... 🙁 Now I'm wondering if I should return the headphones.

Good when It Wants to Connect
The app used to work reliably but now has issues connecting to some of my devices. It’s the BT11 and AirLink. I’m on iOS 27.0.1 and using an iPhone 17 Pro Max
Pretty good, TONS of EQ options for BTR-17
I’m using this to configure a BTR-17. Connection is seamless, interface easy to navigate. The firmware update was fast (though it changed some UI and volume settings so careful you need to manually switch these back).
There is an absolutely incredible database of source Frequency Response tables and target profiles, including a bunch from Oratory. They work well — you could easily waste a day playing with these settings.

Something breaks with EVERY update !!
When the app is the core part of your lineup of products then you need to make sure the app works properly ! Again with the latest update the app is broken. It doesn’t change the DAC filters properly and some of the items aren’t listed properly. Im praying fiio fixes this
