Review summary

Users appreciate the app's wireless Bluetooth audio tuning capabilities and the notable sound quality improvements it delivers. However, multiple reviews mention persistent Bluetooth connectivity problems, app crashes, and the intrusive requirement for precise GPS location access. While recent updates have improved stability for some, the app still suffers from bugs and occasional device detection failures. Additionally, the lack of English instructions makes it challenging for some users to navigate all settings.

Pros

Good Bluetooth functionality with wireless control convenience
Improves audio tuning and sound quality effectively
Interface allows on-the-fly adjustments making manual tuning unnecessary
Stable performance after recent updates for some users

Cons

Bluetooth connection issues frequently reported, including difficulty connecting and cutting out
App crashes or stops responding often, requiring re-entry to function
Requires exact GPS location permission to operate, which users find unnecessary and intrusive
Somewhat buggy user interface with occasional detection problems for connected DSP devices
No English instructions causing a learning curve

Learning on the fly since there is no directions in English.
2023-08-23	ja*****	It's a win with bluetooth functionality and the ability to adjust on the fly. The downside is it's a little noisey, sometimes it takes a few moments to load at start up or ater having toggled away from the app for a few seconds. Also, adjusting the delay results in loud damaging clicks & pops that can damage speakers. I dislike the fact that it REQUIRES YOUR EXACT GPS LOCATION or it won't function! The unit should only need to know it's bluetoothed within 15 ft & secured by PIN entry.
