While I believe this to be an incredible app for managing codecs, I would like to request a refund. I purchased this app to manage codecs for my Bluetooth headphones, but as it turns out Aftershokz only uses one codec. With nothing to manage I humbly request a refund.

Good app, bought premium, needed for specific reason - Extreme Battery Saver. I regularly switch between aptX 48/16 for dual connection and LDAC 96/24 for Hi-Res. Happy to see Aggressive Lock holds setting for Default Codec using the Saver. Problem: I create two profiles, one for aptX & LDAC each, but I can only set one master Default Codec. On Ext Saver only Default Codec sticks even if load a profile. Solution: If possible, each Profile needs to set its own Default Codec then 5-star app.

The latest update has ruined it. I can't change the codec according to headphone and file. It just defaults to the highest settings for different headphones. I don't want to lock it. Now it won't let me switch to sbc from ldac. I figured out how to change to sbc I have to make it the default codec. The answer is yes Reached out to developer. Samsung A14-5G Tried to contact developer no response Now for GREEN headphones I have to change audio quality in developer options

I tried everything for this to work to convert my Phone Only Bluetooth on my Vehicle to also enable me to play Audio from my phone, which is what this advertised to do. However, upon going through my multiple videos and instructions, nothing solved the problem, also in order to get this functionality, I had to pay to become Premium User. I paid the discounted fee, hoping it should work as advertised, but definitely false advertising and no it did not work, and I also paid for something, refund now
